Canopies for gates and wickets: how to weld correctly

Garage doors are most often made of metal structures. You can buy them ready-made or make them yourself. Such structures are subject to special reliability requirements. In addition to the gates themselves, the fittings used for their installation must also have high strength and resistance to damage. It is best to install metal doors on reinforced hinges or forged gate hinges.

This is what classic gate hinges look like

A self-made structure will last for many years if you first draw up a competent drawing of the product and select the right materials and fasteners for it. It is the hinges for garage doors, if the installation rules are followed, that ensure the durability of the doors installed on them. You can buy suitable fasteners at any construction shopping center at an affordable price. Return to contents

Welding the ears

The order of work here will look like this (for convenience, let’s imagine that the hinges need to be welded onto an ordinary metal gate).

First, thick metal plates are welded to the hinges - they are called plates or ears. This is done like this:

• two plates are laid horizontally so that there is a gap of about 2-3 millimeters between them;
• a loop is placed in the gap;
• These same plates are welded to the loop with a continuous seam - one to the top of the loop, the second to the bottom.

The presence of lugs greatly facilitates further work and increases the service life of the gate. They do not allow the fabric to “tear” even with the heavy mass of the entire structure.

How to set up hidden hinges

Like any similar mechanisms, hidden hinges are divided according to the weight they can support. Lightweight models are used on furniture and frame doors, and reinforced ones are used on massive wooden doors. First, let's look at setting up light awnings.

Fine-tuning reinforced hidden awnings is a little more complicated than the previous option, but it is quite within the capabilities of a home craftsman.

Loop welding technology

Before we talk about how to weld hinges on gates, it is worth taking a closer look at the conditions necessary for their normal operation.

Even if the load is calculated correctly, the hinges may not be able to cope with it if their position deviates even slightly from the vertical. They will quickly fail. And the second point: there should be a small gap of 1-2 mm between the hinge body and the support post so that the metal parts of the post and the mating part of the canopy do not touch or rub against each other. The same gap should be left on the side of the sash.

The nuances of installation on supports of different sections

The supporting posts on which the sashes are hung can be round, square or, less commonly, rectangular in cross-section. There is a difference between how to properly weld gate hinges to round posts or supports made of profile pipes.

If the profile pipe has smooth edges without bends or distortions, then it will be easy to cope with the task of how to properly weld gate hinges to square posts. They are installed on the outer plane of the support.

In the case of a round support, you must first decide in which direction the doors will open. Then they find the most protruding line (the middle of the pillar relative to the opening) and step back from it a few millimeters outward - in the direction of plowing. 5-6 mm is enough for the wicket or gate leaf to move smoothly and without jerking around the axis of the canopy. Since it is more difficult to weld hinges on gates to round posts than to square ones, here you need to be especially careful and attentive, maintaining the same indentation size for all hinges.

Installation and welding work

Experienced welders recommend first welding the canopies to the sashes, laying them on a flat horizontal surface. A half in the form of a hollow cylinder is welded to them, and a mating part with a pin (pin up) is subsequently welded to the supports. They retreat approximately 15 cm from the top and bottom edges.

Then the sash with welded canopies is installed in the opening on stands that provide the required distance to the ground, and is rigidly fixed with clamps, pliers and other devices. They do this so that it stands strictly vertically, and there is a gap of 5 mm or so between it and the support. To do this, use a laser level or a plumb line, and spacers of the required thickness are inserted between the elements.

Other craftsmen prefer to first install the gate, and then weld the hinges to both it and the post. There is no big difference, everyone does what is convenient for them.

Another option is to make the upper and lower ribs of the frame whole when making the sashes and cut them after hanging them on the hinges. Source sqezo.ru

Now let’s talk about how to properly weld canopies on gates. The sequence of work looks like this:

• 1.5-2.5 mm thick wire is wrapped and twisted around the loops at the top and bottom to form a gap between it and the welding plane. You can place matches or other objects of suitable thickness, but they fall out, move or break, which is very inconvenient;
• The places where the canopies are attached are marked on the supports and an even long block or profile pipe is applied to them. Fix it level, ensuring a vertical position.

How to install on supports of different sections

The specifics of welding hinges onto poles made of different materials and with different configurations may vary. There are corresponding rules for round, square and profile supports.

We recommend reading: How to cut metal edges for welding

Round post

Welding curtains onto round posts allows for errors in calculating the width of the door leaf. You can allow a gap between the sashes during installation. The design can work properly even with possible sagging.

A column with a round cross-section is conventionally divided into 4/4. Installation is carried out in the area of ​​the quarter, which is located on the side of the planned opening of the gate.

Square post

If the support is square, the installation process requires some skill. The hinges are welded to the corner of the post that is located on the opening side of swing doors or gates.

Profile sheet

Initially, it is worth fixing 2 jumpers, aligning them correctly and fixing them from below and from above. The distance between the parts will ensure free installation of 3 elements. Loops are welded to the jumpers. The corrugated sheet is fixed above the hinges, since during welding it can burn out and lose its original appearance. For supports made of profile sheets, it is better to use garage hinges.

See how it looks in this video:

loops with twisted wire are pressed against the block and the post and are also fixed in a vertical position;

the loops are welded to the supports at 2-3 points;

in the same way, they grab the second (upper) part of the hinges to the frame or leaf of the doors;

when the tacks have hardened, the gate is checked for opening - it should swing open 180 degrees without jamming or warping;

if everything is in order, the sashes are closed again, fixed and the hinges are welded onto the finishing surface with a continuous seam from the bottom up;

cooled seams are cleaned of scale with a hammer and sanded with a grinder to give a more aesthetic appearance

But this work must be done carefully so as not to damage the joint. After painting, the sanded joints will become almost invisible Source i.ytimg.com

Do not open the gate until the welds have completely cooled and gained strength.

Metal gates can also be hung on other awnings, which are secured with screws or nuts. But the welded method is more reliable and durable, especially if you know how to properly weld hinges on gates and strictly follow all the requirements regarding their installation technology.

Briefly about the main thing

There are 6 types of hinges, which differ in the type of fastener and maximum permissible weight, as well as division into specific needs. For example, a mechanism in the shape of an arrow or a cylinder can be used for gates. And through or hidden for the gate.

They are also distinguished by shape, each of which also has different properties. When purchasing mechanisms, you need to find out whether it can withstand a certain weight.

They are attached in two ways: welding and self-tapping screws. Both methods are easy if you know how to use the tools.

It is also necessary to carefully ensure that the hinges do not deteriorate, otherwise they will not last long.

Installing plates

Many inexperienced welders have certain doubts about the possibility of welding cylindrical hinges to a flat surface. There is no doubt that this procedure with round loops is much easier to perform than with square and hexagonal ones.

In order to properly weld round hinges, you need to take care of installing the plates - they are welded to the hinges themselves using a welding machine. It is necessary to do this with an even seam. By welding the plates to the hinges, a convenient platform is created for installing the hinges on the gate itself. These irreplaceable elements are selected in accordance with the weight of the gate and the strength of the material from which the plates are made.

Reinforcing loops with plaits

Some craftsmen weld hinges without using plates. This option is also possible, but thanks to their use the fastening is more reliable.

Installing gates

Before welding the hinges on the gate, the gate leaves must be correctly positioned in the opening of the garage or fence. The complexity of the procedure lies in the fact that the gate should be placed in the opening before the hinges are welded, that is, virtually by eye. To position the gate as accurately as possible, you need to use a building level and a lot of patience. Adjustment of the gate position should be carried out as many times as necessary until the gates are in a level position. Only after precise placement can welding be carried out.

Gate hinges with welded plates

We weld the hinges to the gate

Now let's figure out how to properly weld the hinges on the gate. Despite the apparent complexity of this procedure, it is quite possible to perform it with the proper skill and patience. Welding hinges on garage doors is carried out in several sequential steps listed below:

1. Lubricate garage hinges with welded plates with grease to ensure their smooth movement after installation. Also prepare thin linings for the hinges - their thickness should not exceed 5 mm. They are necessary primarily for round hinges.
2. Make the correct markings of the fabric for the loops. So, it is necessary to mark indentations from the edges of 25-30 cm. The markings are applied with a construction pencil.

Prepared plates

1. Weld the hinges to the door leaf. To do this, first weld the bayonet parts of the hinges, at first only slightly grabbing them by welding, then weld the metal from the bottom to the top, while ensuring the most even seam.
2. After welding the first seam on all hinges, you need to use a level (it is better to use a construction level for these purposes) to check the correct opening and closing of the gate. If no defects are found, you can continue.

Iron loop welded to the gate

1. After the installation of hinges on the gate by welding is completed, you need to carefully process all welds with a grinding machine. The last stage is painting the gates and hinges in any color you like. That's all!

As you can see, attaching the gate hinges yourself is not such a difficult task, impossible to do at home. It is enough to have the necessary equipment at hand and strictly follow the recommendations for action specified in this manual.

If you are installing garage door hinges, weld them in such a way that the doors open outward. Otherwise, big problems will arise after the snowfall.

Loop welding technology

To install the hinges correctly with your own hands, you need to familiarize yourself with the technology of welding them.

Installing plates

Experienced experts advise using small metal sheets called plates. They must be welded when installing round hinges. To install them, you do not need special, hard-to-reach tools.

It is enough to use a welding machine that reliably connects metal elements.

The plates must be welded with an even seam so that they are securely attached to the surface of the loops. Hinges can be installed on the gate only after the plates have been welded.

We install gates

Before installing the garage hinges, they install the gate leaves in the opening. This procedure is quite complicated, since it is not easy to install the sashes yourself. Experienced builders advise using a building level to ensure everything is installed level. It is contraindicated to perform such work by eye, since it will not be possible to install the sashes evenly without a level.

Attaching hinges to supports

Many people who do not know anything about welding equipment and welding believe that welding eyelets to supports is very difficult. However, if you become familiar with the installation features of such products, the work will seem less complicated.

The fastening process is carried out in several successive stages:

• Lubrication of hinges. First, the products are treated with machine oil, and they are lubricated in such a way that it does not flow down the hinges.
• Marking. Marks for welding are made on the fabric to which the loops will be welded.
• Welding to the canvas. To ensure that the structure is securely fastened, the bayonet parts are first welded, after which everything else is secured.
• Welding check. To check the evenness of the installation of the hinges, use a building level.

Selection of loops and their number

Please note that welded hinges most often have a round cross-section and, when assembled, will resemble a cylinder. But their cross-section is teardrop-shaped, with a point along the walls

The configuration will not affect the performance characteristics of the product in any way, and it is also selected solely for ease of installation - for some it is more convenient to attach some, and for others the rest. But in fact, it is not enough to know exactly how to weld the hinges to the gate - first you need to calculate the load on them and decide on the number. This is not so difficult to do if you know about the weight of the sashes.

Hinges that do not have plates can withstand a maximum of 4 quintals depending on their length and diameter, as well as the thickness of the metal. And the loops with plates that take on all the loads that are designed for heavier weights - they can withstand up to 6 centners. Knowing the design type of load on the hinges, as well as the structural weight, you can determine their required number. Naturally, less than two pieces per sash will not work. And if the gate is heavy, then the number of canopies should be 3-4. The additional loop needs to be installed slightly lower than the top one, which will bear the main load. By the way, you can even strengthen simple hinges yourself by welding to them plates cut from thick metal of the required size. The weld seam should be continuous.

What should gate hinges be like?

Metal gates are most often installed on garages and fences that protect the perimeter of the area. First of all, they perform security and protective functions, and only then decorative ones. Products in this category can weigh from 200 to 1500 kg. Therefore, in order for the structure to serve well for many years, it is necessary to select only fittings that are suitable in terms of strength.

Drawing with dimensions of hinges for gates
Buying hinges today is not a problem.
The construction markets offer a wide range of different components at affordable prices. For those who like to do everything with their own hands, it will not be difficult to make a drawing of the gate and, having decided on the parameters, buy reinforced fastenings for the gate. If components that can be fastened with self-tapping screws and bolts are suitable for wooden structures, then welded hinges are preferable for metal products. Poor quality hinges or hinges that do not fit the gate lead to the following problems:

• cannot withstand the applied load and become deformed;
• the gate begins to sag;
• The doors no longer open easily and close tightly.

Properly selected fasteners will help to avoid such problems. The most inexpensive and simplest hinges consist of a pin and a cap on it. This fitting is recommended exclusively for fixing light sashes.

If the gates are heavy, then the hinges for them should be purchased with a more complex device. Components such as bearings in hinges help redistribute the weight of the sash, which allows the hinges to last longer without any defects in operation. Such fastenings are often supplemented with non-removable pins.

Buying high-quality hinges that best fit the gate means:

• provide the gate with all conditions for long-term service;
• forget about creaking and grinding noises when operating the sashes;
• provide the entrance to the yard or garage with maximum protection against burglary.

Modern fittings for garage structures function perfectly in any weather. Permissible temperature range:

• from – 400;
• up to +1200.

Welding

Next, you need to prepare the hinges - clean them of rust and fatty deposits, lubricate them with grease or other similar compound. This will prevent so-called hinge sintering when you start welding.

Now you need to use the welding machine: first, the fittings are welded to the gate leaf, and only then to the support pillars. In this case, it is necessary to constantly monitor the quality of the resulting seams.

When all welding work is completed, it is advisable to process the new seams with a grinder.

You can weld hinges on a gate, garage door and on a metal door according to the same scheme as described above.

However, it should be noted that the craftsman usually has the opportunity to weld the fittings onto the door at the moment when it is in a horizontal position on a flat area, which greatly facilitates the process.

This does not work out with gates: the support pillars, as a rule, are installed much earlier than the actual installation of the curtains begins.

Attaching the hinges

Gate hinges are fastened in several ways, however, the most popular method of fastening remains welding. Proper welding is available only to those who have already held a welding machine in their hands more than once. Therefore, if you have no experience, you should practice before you start attaching the gate. If the gate is secured in accordance with existing building regulations, then it:

• will not sag over time;
• will open/close easily even after many years.

Basic truths

The process of installing hinges can be considered using the example of a metal gate. In order for it to properly perform its main functions, a number of conditions must be met when welding hinges:

1. Provide a gap between the support post and the gate frame, which should be 3-5 mm.
2. Provide a gap of several millimeters between the hinge and the gate frame by welding plates - metal plates of the required thickness - to the hinge. In total, for each loop you need two strips, the length of each of them is 2 mm less than the length of half.
3. The optimal distance from the edge of the gate to the loop is 15-20 cm. If you need a middle loop, then it is located exactly in the middle between the outer loops.

First, the lower part of the fastener (with the pin) is welded to the post, then the upper part (with the groove) is welded to the sash.

A properly assembled structure should have the following parts:

• a loop;
• plate; wicket frame;
• support pillar;
• lower part (with pin);
• upper part (with groove).

All loops must be coaxial, that is, their centers must be on the same straight line. The alignment requirement is extremely important. It is on its compliance that it depends on how evenly the weight of the gate will be distributed on the fastenings and, accordingly, how long they will last.

To work, the master will need:

• welding machine;
• metal plate for making plates;
• Bulgarian;
• hammer;
• plumb line;
• oil for lubricating hinges;
• protective equipment - mask, gloves, overalls.

At the preparatory stage, you should mark the gate frame and sash, determining the places where the hinges will be welded. Clean them from dust, dirt, and rust. To do this, you can use a wire brush and solvents. Next, a similar treatment is performed on the surface of the hinges, and lubricant is applied to their inner part.

The traditional welding method involves the installation of plates at this stage, for which it is recommended:

1. Take 2 identical plates of the required thickness and length. Place them so that there is a gap of 2-3 mm between them.
2. Place the bottom part of the loop on them.
3. Weld the loop to one of the plates (in this case, to the right one).
4. Do the same for the top of the hinge and weld it to the left plate.
5. Then you need to install the shutters in the working position and fix them.
6. The plates with the lower part of each hinge are spot welded to the post, then the upper hinge elements are inserted into the lower parts and spot welded to the sash. After checking the alignment of the hinges and the operation of the gate, final welding is carried out along the contour of the plates.

Installation on garage doors and gates

The hinges are attached in two ways: welding and screws. They are similar to each other; in both cases, the fasteners go to the post and the front of the sashes. Let's first consider how to properly weld hinges onto a gate or garage door:

1. The structure must be placed on a flat surface and the places where the elements are expected to be attached must be marked.
2. The hinges must be lubricated with oil.
3. The canvas is installed vertically along its plumb line and both parts of the loop are tacked by spot welding.
4. Afterwards, the location of the hinge axes is checked and the top one is tacked. Next, you need to check that there are no gaps, cracks and that the sashes move well. When everything is in order, it is necessary to finally weld.
5. All welding areas are cleaned with an angle grinder and then painted.

When welding moving parts, you should remember safety precautions and monitor the flow of current. It is best to make a connection using cross welding so that the seam is stronger and the errors that were made during fastening are less noticeable.

Welded fastening Source yandex.net

The method of connecting hinges for a wicket gate using screws can be compared with installing an interior door, only the mechanism will be wicket:

1. First, you need to attach the wicket loop to the front of the leaf using wood screws (2-3 pieces).
2. Afterwards, the gate is laid together with the support pillars on a level place and the places for mounting the second part are marked.
3. If a recess is needed on the canvas for the mechanism, then it can be made with a stomp.
4. The gate is attached with self-tapping screws to the support posts.

You can attach hinges for swing gates in the same way. The steps are the same, only on both sides.

Types of loops

Taking into account the GOST classification, gate curtains are divided into the following categories:

1. Cylindrical.
2. Through.
3. Hidden.
4. Articulated.
5. Decorative forged.
6. Teardrop-shaped.
7. Adjustable.

Cylindrical (regular and reinforced)

Mechanisms with a cylindrical configuration have a support bearing. They are used on small gates with permissible loads of up to 400 kg. Models with reinforcement have special plates that help distribute the load evenly over the surface of the post or fittings. The modification is in demand for products made from profile pipes. They are usually welded to garage doors using an ordinary welding machine or secured with a screw connection.

Depending on the side of placement, reinforced models are available on the right and left. The standard diameter of the product is 50 mm, and the permissible load is 600 kg.

The permissible load on hinges with a support bearing is 400 kg, on reinforced ones - 500 kg.

End-to-end

If it is not possible to secure the curtains by welding or screwing, a through option can be used as an alternative. To install the mechanism, you will need to drill mounting columns along the length of the frame and place part of the retainer in them. The final fastening of the product with your own hands is done with nuts of the appropriate size. Such fasteners can handle loads of up to 200 kg.

The permissible load on through hinges is 200 kg.

Hidden

Unlike previous varieties, hidden loops are well camouflaged, because they are installed in a sash frame and welded to the frame and the transverse surface of the pillars from the inside. It is quite difficult to detect the placement of such fittings, which increases its resistance to burglary. Such loops are used at those facilities where valuable property is stored. The products are distinguished by their durability because they are isolated from harmful influences.

Installation diagram for hidden hinges.

Articulated

This group includes reinforced and semi-hinged elements. In the first type, the axial rod is attached to 2 halves of the card. This provides a cylindrical joint that rotates easily. The half-hinged option involves placing the axis rod in only one half of the card. The design is not particularly reliable.

Decorative forged

They are considered an outdated type of gate hinge, which does not lose popularity despite the availability of more effective solutions. Most often, forged curtains are found on wooden fences and are used as a decorative element. At the same time, there are mechanisms on sale that are not inferior in strength to modern analogues.

Decorative loops.

teardrop-shaped

Teardrop-shaped fasteners are equally effective on metal and wood structures. Their popularity is due to their increased strength and resistance to mechanical loads. In addition, the fittings look original.

Adjustable

This option is suitable for any garages, warehouses and other similar facilities. Due to the design features, the mechanisms allow you to adjust the position of the sashes in height. Such hinges are in demand when there is a possibility of deformation of the support posts. They can handle loads up to 200 kg.

Adjustable hinges, permissible load - 200 kg.

Selection by form

Hinges for swing gates have their advantages and disadvantages, and this factor requires attention.

Fastening to the gate

1. In some cases, it is necessary to weld the lugs separately to ensure secure fastening.
2. If the gate is three meters high and covered with corrugated sheets, then cylindrical structures can be installed, including forged hinges.
3. By using support hinges with teardrop-shaped bearings, the welding seam is uniform, so the installation process is simple.
4. The arrow hinge is used on gates made of no matter what materials, be it wood or metal. Moreover, the gates are given additional strength and special elasticity.
5. If the hinges are cylindrical, then installation of the door leaf will be difficult. This structural element is considered the most reliable.
6. Overhead hinges should be selected after calculating the effective load. The gate is successfully attached to a mechanism with an eccentric. If the gate weighs more than 200 kg, then hinges with wings are used.
7. Automated systems use induction loops based on a magnet.

Types of hinges and their installation

Loops can be divided into several types:

Cylindrical with bearing for support.

Used for mounting standard gates that are not too heavy in weight. It is not recommended to load such systems with a load of more than 0.4 tons since this is their maximum permissible weight. This information should be asked before purchasing because it may vary for each model and brand.

They look like a cylinder that is divided into 2 parts. One of them has an end in the form of a rod, which, during installation, enters the second part with an empty core and a ball at the bottom. This bearing makes the mechanism smoother during movement if too much load is applied. On one of its sides there is a special place for installing a plug, which can be removed.

Cylindrical hinges for gatesSource vorota-goroda.ru

Reinforced structures in shape.

They cope with loads of up to 0.6 tons and differ from the first ones only in the fastening plate, which makes it possible to correctly distribute the mass over the surface. Such a mechanism can be installed using welding or, as in interroom passages, with self-tapping screws, and the opening of doors when using such a hinge can be in both directions.

This fastener is made of durable steel, which increases the maximum permissible load weight and durability of the product. Before purchasing, it is recommended to check the bearing for special markings.

Through.

Used when welding or other fasteners cannot be used. To install them, the gate support is drilled through and secured with nuts on the other side. Such loops can only withstand small weights, their maximum is 200 kg. They are made right-handed or left-handed, and can also be equipped with canopies.

Hidden.

They have a special design that can be easily hidden if the gate is closed. They are attached to the side of the post, which acts as a support, and to the inside of the frame. The advantage of this design is that these hinges can only be dismantled with special tools.

Hidden mechanismSource www.travelnews24.ru

Three-section overhead (magnetic).

They are made as hinged or semi-hinged, and can be used for gates with a large weight. There are three types: decorative, standard and removable.

There is also a difference in the shape of the loops:

1. Cylindrical. They are tightly fixed on the surface of the gate, as well as smooth and easy rotation of the mechanism.
2. Square. When installing, you need to step back a little from the frame. The fixation is more reliable than the previous ones.
3. Hexagonal. Universal hinges that can be fixed both cylindrical and square.
4. Teardrop-shaped. They are used for various structures and have high strength and resistance to loosening.

When choosing gate awnings, it is important to ensure that they match the material. If the hinge doesn't fit metal or wood, it won't last long. . Drop-shaped loopsSource news2.ru

Classification according to GOST

Today on the market you can find a huge number of all kinds of hinges from different manufacturers, shapes, types of fastening, and external design. High-quality hinges for country gates and gates are divided into certain groups according to current GOSTs so that the average person does not get confused when choosing them. This makes it much easier for customers to select the necessary components and navigate their types and prices. Knowing the features of each type, the client can easily choose the right part for fastening the doors.

The main types of hinges for modern gates are the following:

• cylindrical type with support bearing;
• secret type for hidden installation;
• through-type curtains;
• models with a reinforced structure for mounting on gates;
• three-section type for installation in industrial facilities.

Now, let's take a closer look at each of these types in order to evaluate the features of each of them.

When choosing fasteners, it is important to know the advantages and disadvantages of each type, this will allow you to choose exactly the model that is most suitable in a particular situation.

Cylindrical with support bearing

This type is made in a standard form and is not particularly different. Outwardly, they look like a cylinder of two halves. In the first part, which is the top, there is a pin, and in the second, which is the bottom, there is a hole into which the first part is inserted. Some models have a ball-type bearing inside to facilitate movement.

Such curtains are used in structures whose weight does not exceed 400 kilograms. For heavier systems, reinforced special cylindrical hinges are used. The connectors are fastened by welding. The ball bearing is installed in the hole in the lower curtain. Often, on the back side of the bearing there is a hole with a plug that makes it easy to lubricate and clean it. This small revision will improve the performance.

Up to four cylindrical hinges are installed in such structures to ensure the best movement and reduce the load on each. In some models, the bearing is not installed in the lower part, but between two moving elements. This modification greatly simplifies the opening and closing process. However, such a mechanism is difficult to lubricate, since to do this you need to lift one of the flaps.

Secret hinges

The main advantage of this type is hidden installation, because the design reliably hides them inside when the system is closed. A special feature of the design is that the hinge itself is hidden in the sash frame and attached to the side of the support. The advantage of such a fastening system is that it reduces the chances of hacking, because the loop is difficult to find and almost impossible to dismantle without the necessary tools.

Through-type hinges

The design feature of this type is that the two curtains are connected by a rod that enters the upper part and protrudes slightly from the lower part. The simplest design consists of two halves and a pin. This type is widespread on the market and is used mainly for office doors; the design can withstand a weight of up to 200 kilograms.

Assembling elements is somewhat reminiscent of a construction set, because each element has several ears. It is important to note that there can be several such elements on the door, which significantly increases reliability. Sometimes, bearings are installed between the hinge elements, allowing movement to occur more smoothly, with less effort.

To prevent the possibility of hacking by removing the pin, there is a special plug on the bottom. Basically, it is welded, less often screwed.

If the plug is not provided for by the design, then a special limiter is installed on the top part, which does not allow the pin to be removed. This prevents hacking without special tools.

Reinforced gate models

Special reinforced models of cylindrical hinges allow them to withstand greater loads than conventional ones. They are made of metal of greater strength, as a result of which the walls and rods are thicker. This allows you to increase the load-bearing capacity of each loop.

This type has modifications in which bearings are added. They have special markings that indicate increased wear resistance and maximum pressure on them. This makes it easy to open and close heavy gates.

Three-section industrial

This type is in great demand in structures with significant weight of the connected web. Structurally, they are similar to through models, however, they are more reminiscent of cylindrical ones. Their design consists of two oppositely directed pins onto which cylinders are placed and welded to the posts.

It is impossible to disassemble such a structure without using a grinder or other special tool.

Materials and tools

To do the job well, you will need professional tools

In addition to the welding machine, you will need the following tools and consumables:

• welder's protective mask;
• measuring instrument: ruler, tape measure, building level;
• lubricant for hinges - grease or a composition similar in properties to it;
• An angle grinder will be needed to clean up welding seams and dismantle an incorrectly installed hinge group.

Support pillars are best made from a profile pipe of square or rectangular cross-section. This will ensure the reliability of the structure and facilitate the installation process of the canvas.

Tools for work

Welding tools

It should be noted that even specialists, let alone inexperienced welders, cannot always perform this work correctly. They may encounter many difficulties. A beginner will read these lines and may give up. Well, is it possible to do it yourself? It turns out that it’s quite possible, even for people who have no experience. All you need to do is know how to cook at least a little and be attentive. Worth a try. To work you will need the following tools:

• protective mask and gloves.

Beginning of work

The cylindrical shape of the hinges often makes inexperienced welders wonder: “Does this even weld?” It's cooking. Loops made from a hexagon or tetrahedron are actually more difficult to weld. Using the correct technology, the loops are first welded to special plates. It is advisable to do this on a flat horizontal surface, for example, on an anvil (at the same time, you can attach the “minus” of the welding machine to it). An essential requirement: the plates must be welded to the hinges with a continuous seam.

It is not difficult to choose a suitable size dress. We take into account the weight of the gate and the strength of the material from which they are made and determine by eye what length of welding seam can withstand the weight and not allow the door structure to deform. The plates provide a convenient working “platform” for welding work, and they also serve as distribution plates for the door leaf, which prevents the latter from “breaking” even with the overall heavy weight of the door structure.

Gate installation

Welding of hinges with already welded plates must be done permanently, having previously placed the gate in the “native window”. That is, the gate will have to be fixed “idle” and reach its required position even before the start of welding work. The position of the doors must be checked and double-checked as many times as the average first-grader knows the numbers - at least ten.

Welding work

After a thorough check of the location of the gates and the pre-measured and marked fields for the plates has been made, welding work can begin with the lower hinges on the posts. Vertical welds are the most difficult job for a welder. But thanks to the plates, even an inexperienced welder can handle them. Once one bayonet part of the hinge on the sash is welded, you can use a laser level to verify the correct location of its axis and to determine the exact location of the second bayonet hinge.

Completion

After carefully welding the bayonet parts of the loops on the pole, you will need to attach the inserted upper parts of the loops to them immediately with the balls. Then press the baited part against the door leaf as tightly as possible and continue welding work.

At the end of the welding work, the seams can be processed with a grinder.

This technology has been successfully used by all door installation services for a long time. It will not be difficult to do this yourself if you have welding skills and the necessary equipment with consumables:

• Metal door hinges;
• Plates/plates;
• Welding machine;
• Electrodes;
• Bench hammer;
• Welding mask, gloves and overalls;
• Bulgarian.

Please note that the gates must open outward, because if the gate opens inward during heavy snowfall in winter, this can become a big problem!

Installation nuances

To ensure that after attaching the hinges they do not fall off after a few days, you need to know the main installation points:

1. To begin with, it is recommended to prepare the tools necessary for installation, for example, a hammer and welding or screws and a drill. Also during the installation process you should use a level and a tape measure (or ruler) for more accurate measurements.
2. Before starting work, you need to make a sketch of what the finished result will look like. During all stages, you must carefully monitor safety.
3. When welding individual plates, it is necessary to give a uniform load on them.
4. First you need to make markings for fastening the hinges to the gate posts and the shutters themselves.

Useful tips for welding gate hinges

Incorrect fastening of iron hinges to gates leads to poor operation of the gates. Over time, they will have difficulty moving or may not be able to function at all.

To prevent such troubles, experienced professionals give several useful recommendations.

1. When working with straight hinges, it is better to weld on a horizontally lying gate (the leaf can be placed on the ground).
2. Before welding, it is recommended to make a backing 1/2 loop long. The part should be placed under the bottom of the loop, and the top should be grabbed from the end side.
3. When attaching hinges to a round post, make an external allowance of 5 mm. When working with a rectangular support, fixation is carried out flush.
4. Before final fastening, a rectangular block is placed along the hinges and the devices are corrected if they are crooked.
5. It is better to weld with small tacks. Actions are performed twice and from all sides.
6. Before fixing the hinges from the inside, it is necessary to check the ease of movement of the gate in weight. Incorrect operation is corrected by welding, soldering several points on the outside.
7. To avoid sagging of the sashes, before the final welding of the hinges of the fabric, the stand should be closed and placed in the center.

While the hinges are hot, the gate does not open. The structure can be used as soon as the devices have cooled down.

Operating instructions

After installation, you need to know a few rules for caring for hinges:

• it is necessary to monitor emerging defects;
• service after a certain time specified in the instructions (often 3 months);
• it is undesirable to keep them in one position for a long time, since the hinges begin to rust when idle, which leads to unpleasant consequences;
• to reduce the load on the fastenings, you can install a support under each blade, then the service life will be extended;
• Periodically, the mechanism must be cleaned of grease and old oil.

If corrosion occurs, it is necessary to dismantle the removable hinge elements and clean them from dirt and rust using fine sandpaper. Rub the rotating mechanism with paste, and then lubricate it with grease. To avoid freezing, it is better to do this when it is warm outside. If you use these tips, your gate canopies will last a long time.

Preparatory work

They start by welding the plates to the hinges. This step can be skipped if you are using ready-made canopies with mounting plates or when mounting them on round poles of small cross-section. The plates are cut from sheet steel using a grinder, choosing sheets with a thickness of at least 5 mm.

Before assembling the hinge, its internal part (the place where the bearing is located) is carefully treated with lubricant, and the area allocated for welding is cleaned of dust and rust. Cook on a horizontal surface. Two plates are laid side by side along the long side with a gap of 2–3 mm. Half of the canopy is placed on top, welded to one of the plates with a continuous seam. A similar operation is performed with the second half. The resulting seams are carefully cleaned.

Important: according to fire safety rules, welding work is carried out either on unpainted or fully painted, dry parts. Paint that is not completely dry can ignite from a spark.

Work safety

Remember that the organization of welding work, no matter what class, will always require the contractor to comply with some important rules that relate to safety precautions. After all, this is an important condition, which means you must never forget about it; first of all, you need to prepare the appropriate protective equipment.

It is necessary to carry out welding work exclusively in a well-ventilated area; this can also be done in the open air, but do not forget that flammable and combustible materials must be kept at a sufficient distance from the work you are doing.

Look carefully at the photo before purchasing, because you now have instructions. Decide which hinge option is right for you and then you can make a purchase.

Additional recommendations

Failure to comply with the requirements when performing welding activities can jeopardize the final result. To avoid this, just consider the following recommendations:

1. Before assembling the hinges, you need to prepare and analyze a diagram showing the placement of the fittings. This minimizes the likelihood of redoing the work.
2. Hinges with a straight configuration are best attached to gates placed on a flat surface.
3. The gate may only be opened after the seams have cooled completely.
4. On round posts the curtain is extended 5 mm outwards, on rectangular posts it is welded flush.
5. The seam is made from bottom to top.

Metal gate hinges

Garage doors are typically heavy metal doors that are used on a daily basis.

Drawing with dimensions of gate hinges
Most often, such doors are characterized by a large mass.
For wooden and metal gates, various components are used, which can be purchased both in stores and on the Internet. Those who like to do everything with their own hands, before making a purchase, need to know for sure what kind of gate hinges they need. Metal structures can differ greatly from each other in appearance, type, weight, method of functioning and purpose. Before you go to the store for hinges, you need to draw up a drawing of the product and make calculations. The expected load on metal garage doors must be taken into account.

Hinges for swing garage doors, like the gates themselves, can be different. The more complex and heavier the doors, the more complex the design of the gate hinges that correspond to them. The most popular are cylindrical hinges with bearings, booms, products with several sections, etc.

Example of installed hinges for a garage door
Heavy metal gates can be attached either to posts or directly to the frame itself. Special fittings provide even large structures with perfect rotation relative to the mounting axis. Only high-quality components from a reliable manufacturer will allow the doors to constantly open and close with smooth movements and without grinding. Buying products of dubious quality means jeopardizing all the work done on the manufacture of the gate. Return to contents

Varieties

Hinges allow you to smoothly open and close the gate without making a single sound

All types of loops can be divided into three groups:

• classic;
• decorative;
• hidden.

The first ones have a normal appearance, because the consumer encounters them quite often, since they are installed on entrance and interior doors. Even though we are talking about gate hinges, they are not particularly different. In this case, there is one aspect that plays an important role, this is the special treatment of the material, thanks to which the hinges will withstand any weather conditions.

Increased reliability is one of the most important characteristics during hinge production. This element must withstand heavy loads, because the gate is heavy and is also used regularly. Therefore, additional bearings are often installed to improve the data. You can often find hinges without ears on sale, since the consumer can independently weld them to the product, depending on the structure of the system.

Articulated

Hinges are in great demand and this can be reasonably explained. They allow you to easily and smoothly guide the gate and are resistant to breakage, which is an important indicator. Some of the hinges of this device are designed for installation on large gates, as they can withstand heavy loads. Spontaneous opening and closing is excluded if the structure itself is installed correctly and this fitting option is selected.

For the manufacture of hinges, durable and reliable metal is used, which has excellent performance. Heavy gates will last a long time with this installation.

Hidden

They resemble classic ones, but the main advantage is their increased burglary resistance, and for many this is the main indicator. Removing such gates will be problematic and will also take a lot of time.

Decorative

According to the principle of operation, they do not differ from the classic ones, but they look more aesthetically pleasing and can emphasize the design of the gate installation. Hinges can be antique, forged, or in a certain style. Welded structures are strong, reliable and provide safety.

teardrop-shaped

They take their name from the shape of the bearings, which are an integral part of the structure. Such hinges are in demand during the installation of garage and entrance gates, steel doors and even safes. Thanks to the teardrop shape, the problem of uneven movement is solved, so if you have heavy swing gates, this option will be one of the best. When opening, you will not hear creaking or noise, the structure will move smoothly.

Cylindrical

They are suitable for a massive frame where strength and resistance to heavy loads are required. They have support bearings that do their job for a long time. In such hinges the crown will be hidden in the body.

Adjustable

This type of hinge is distinguished by its ability to be adjusted, which is an indispensable advantage in certain situations. Thanks to them, you don’t have to worry about the sashes jamming. As for the cost, it all depends on the variety you have chosen, as well as the manufacturer, because everyone sets their own prices.

Pros of hidden awnings

Hidden hinges for doors are now in quite high demand and the reason for this is a number of undeniable advantages of these mechanisms.

• Hidden canopies are anti-vandal fittings; these mechanisms are not visible, which means they cannot be affected in any way, for example, by cutting them off;
• The range of hidden awnings is impressive in its diversity; there are awnings in furniture design, for light cabinets, and at the same time, powerful metal hinges for doors and a quarter are produced;
• Door canopies for hidden installation are especially valued in furniture production; such fittings do not spoil the appearance of the products;
• The amplitude or opening angle of a hidden canopy is often greater than that of its traditional counterpart;
• Hidden hinges are made of either stainless steel or high-strength alloys and can withstand quite heavy loads.

How to properly weld hinges on gates - procedure

Garage doors are an indispensable element of any garage, which performs both a protective and decorative function. When installing gates for a garage or other purposes (for example, for a yard), the question almost always arises of how to weld the hinges onto the gate so that it serves you as long as possible.

Correct welding is of decisive importance, because incorrect formation of the weld and various other defects can significantly reduce the strength and reliability of the entire structure, and also affect the reduction in the service life of the gate. How to ensure the security of property in your garage (you can install a lock for this) and ensure the correct installation of door hinges? This detailed guide to action will definitely help you.

How to choose the right hinges

Gate hinges are a mechanism that consists of at least two parts. When they are connected, a hinge is formed that moves and helps to rotate along the axis without difficulty. Such a mechanism, depending on its type, will allow the gate or wicket to open 90 or 180 degrees. If desired, you can make them open in one direction or both, which allows you to determine the required functionality. But when choosing, you need to look at several criteria:

• the mechanism must be strong;
• it is necessary to look at the maximum weight they can withstand;
• the largest opening angle must be selected depending on what they are purchased for;
• how they will be installed;
• the raw materials from which the hinges are made;
• design features.

If you carefully study this issue and select gate hinges that are suitable for a specific purpose, you can get an excellent result. In this way, you can make a product that will last a long time and will not lose its qualities over time.

Loop selection

The correct choice of hinges for metal gates. gates and doors should be based on several factors:

• determining and selecting the type of loop;
• determining the number and overall dimensions of the loop.

Types of loops

First of all, welded hinges differ in shape. They can be:

• cylindrical. A variation of this group is the welded drop-shaped loop;
• square. They are used extremely rarely. Currently practically not produced;
• hexagonal.

The main types of welded loops, differing in shape

Experts recommend choosing cylindrical or teardrop-shaped hinges, since this type is the easiest to install.

All welded hinges can be additionally equipped with a ball that acts as a bearing. The ball makes it easier to open the door and reduces friction, which negatively affects the life of the fittings.

Welded hinge equipped with a ball bearing

Also on sale you can find reinforced welded hinges, which are used for installation on a metal door of large size or weight. Additional plates allow you to evenly distribute the load on the hinge, which increases the service life of the product.

Welded loop complemented by metal strips

The most optimal option for a welded loop is a cylindrical ball loop, supplemented with strips. It is this kind of fittings that will serve for a long time without unnecessary problems.

Types of gate hinges

Before installing opening elements for gates, you need to understand the main types of hinges. Varieties of loop products differ in the material from which they are made and in shape. Distinctive features also include service life and appearance.

There are four types of hinges that are most often used when installing garage doors:

• Cylindrical. This type is attached to gate leaves and posts. It is cylindrical hinges that are most often attached to gates, as they ensure their smooth opening. The design consists of a pin and a metal cylinder that is put on it.
• Reinforced models. The products have durable metal bearings, as well as additional iron plates that make the hinges much stronger.
• Through. They are installed in racks and attached to them with bolts and nuts. Experts advise using through structures to hide the hinges in the supports. The main disadvantage of through-type products is the complexity of installation.
• Three-section. They are considered the most expensive and reliable hinges, which are installed to additionally protect the gate from burglary.
