Welded and masonry mesh: types, sizes and applications

What are welded mesh and how are they produced?

Welded mesh is a high-quality metal structure of specified geometric dimensions. Welded mesh is made using a special technology from steel rods perpendicularly connected to each other by spot contact welding. This technology ensures maximum reliability of fixation of all elements, guaranteeing strength and durability, as well as the ability of the welded mesh to withstand various harsh conditions.

Certain types of steel are used to make welded wire mesh. Most often, low-carbon steel or stainless steel is used in production, since these types of steel make the welded mesh resistant to water and corrosion. Steel is used because it is cheap and easy to bend and cut.

Making mesh from small diameter wire

For the production of welded mesh, machines are used that ensure strong welding of wire sections located at right angles to each other. The intersection points are tightly soldered by spot welding.

Subject to proper setup and quality maintenance, modern machines provide maximum productivity, precise mesh cell geometry, material savings, minimum failures and good profitability by optimizing energy consumption.

On the market you can find several modifications of equipment for the production of welded mesh. Accordingly, it will not be difficult to select units of the required power. The RL 2000 is considered one of the most popular models among manufacturers.

These machines show the best results when working together with SPO-70 broaching mills. The devices are equipped with the option of stepless electromagnetic speed control. Welding is provided by three-phase electron. The cost of the kit will be about 350 thousand rubles, and a 380 V electrical network will be required to provide it.

The raw material for the production of welding mesh is stainless, galvanized or carbon steel wire with a cross-section of 1.2-4.7 mm. At the same time, the size of the cells is dictated by consumer demand, but technologically they can be of any size.

The high productivity of the units makes it possible to carry out one-time deliveries of large volumes of products of various ranges. Loss of production capacity occurs during wire threading and material replacement processes. Today, equipment manufacturing companies are actively developing automatic raw material supply systems. The most promising lines are those with two unwinders and two wire feed channels. In other words, if the wire feed stops on one channel, the machine will automatically switch to the second. As a result, downtime is reduced. At the same time, it is still possible to program the length of the web within a range of up to 80 m, and the welding speed will be up to 100 rows per minute.

Making a mesh from a metal rod

The algorithm for producing welded mesh from steel rod is quite simple, so even a non-mechanized line will be sufficient for the production of small volumes. However, if an enterprise wants to expand its range with a product that is widely in demand among consumers, it makes sense to purchase automatic equipment. The level of automation is dictated by the diameter of the feedstock (metal rod): the smaller it is, the easier it is to mechanize the process.

To make a mesh from large-diameter reinforcement, the rods are cut into measured sections and placed in the trays of a welding machine - for longitudinal and transverse rods. Then the longitudinal rods are laid out at a given distance from each other, and the second tray, moving along them, ensures that the transverse ones are laid out. Depending on the equipment model, moving parts may vary.

When the rods touch at the place of their intersection, they are mutually fixed using a special apparatus, and then soldered using contact welding.

At the same time, the quality of the mesh - the final product - directly depends on the characteristics of the raw materials. Thus, the presence of bends, rust and other defects is fraught with poor “adhesion” of welding and, as a result, defects.

Application options for welded mesh

Welded mesh has a huge range of applications. Despite their lightness and flexibility, welded mesh has a robust design and is durable. This means that welded wire mesh systems are ideal for applications where installation with less flexible wire systems may be difficult, and where meeting the highest standards of durability is paramount. Ready-made welded mesh is much more convenient to use than bar reinforcement, which requires a bundle, which saves time and money when carrying out work. You can use welded mesh when:

1. Carrying out plastering work.
2. Screeding of floors, ceilings, foundations. When welded mesh is used in this way, it prevents cracking, shedding, and helps maintain the geometric integrity of the building element/structure.
3. Installation of brick and block masonry. Reinforcement with welded mesh can significantly increase the strength of the structure, resistance to loads and various adverse effects.
4. Road construction to strengthen foundations.
5. Laying sidewalks and paths.
6. Installation of fencing, fencing.
7. Use in agriculture. Welded mesh can be used in the manufacture of cages and pens.

Advantages of using welded mesh

1. High strength. Welded mesh is resistant to deformation, stretching, and tearing. Due to the increased diameter of the steel rod, it is able to withstand significant loads while maintaining the specified cell geometry. The strength of the welded mesh is affected by the steel core and its thickness. The strength of welded mesh is proportional to the diameter of the wire and inversely proportional to the mesh size - large cells make the mesh “weak”.
2. Resistance to various weather factors and temperature changes. These characteristics make it possible to use welded mesh outside buildings (on the street), inside wet, unheated rooms.
3. Moisture resistance. The galvanized coating protects the masonry mesh from corrosion.
4. Compatibility and excellent adhesion with any mortar mixtures, including concrete. Reliable adhesion ensures the durability of the reinforced structure, the absence of peeling and destruction.
5. Compliance with sanitary standards, environmental friendliness.

Welded mesh coating options

Welded mesh differs in cell sizes, wire diameter and metal processing method. In other words, the choice of welded mesh for different tasks is carried out based on the type of surface treatment and cell size. The presence of a protective coating extends the service life of the welded mesh and allows long-term use in open spaces.

1. Non-galvanized welded mesh is a simple and cheap option and is used where aesthetics are not required. For example, when pouring a floor, in masonry, when equipping entrances. But when used in conditions exposed to atmospheric precipitation, non-galvanized mesh requires painting, otherwise it will rust and lose its characteristics over time.
2. On the contrary, welded galvanized mesh is protected from corrosion, durable, and has a high degree of aesthetics, which is why it is often used in the construction of fences. Stainless steel is considered durable, aesthetically pleasing and reliable, even when used in damp conditions. Buying welded mesh of this type will be more expensive, but you are guaranteed to get quality and durability.

   Welded stainless steel mesh is produced using special production technologies:

   • galvanic galvanizing is the process of applying a protective layer up to 20 microns by electrochemical action on the workpiece.

   Hot-dip galvanizing is a complex technological process that allows you to achieve protection of 60 microns. This technology provides a high degree of corrosion protection even in the event of mechanical damage.

For additional protection, the mesh is not only galvanized, but also covered with an additional layer of polymer protection, which is done after welding. This not only adds aesthetics, but also extends service life, increasing the degree of corrosion protection. Welded mesh with a polymer coating is not afraid of a chemically active environment. Using this material, you can equip a fence made of welded mesh, as well as partitions in warehouses and enterprises. The production process involves dipping the mesh into a polymer solution, which creates a layer on its surface of about 0.5 m.

Product Specifications

Technical features are determined by what the welded mesh is made of. For its manufacture it is used:

• wire profile periodic material;
• wire material with a trapezoidal cross-section;
• wire with a T-shaped section;
• round shaped wire.

Welded mesh standards allow different directions of working reinforcements.

In addition, the grid can be:

• reinforcement;

Different brands of products differ in the following parameters:

• wire diameter;
• map areas;
• cell size.

Depending on the wire manufacturing technology, the mesh can be:

• galvanized;
• non-galvanized;
• with polymer coating.

The finished product is not exposed to temperature fluctuations and climatic conditions; it is practically not subject to deformation. The polymer-coated grille has water-repellent properties and is therefore not subject to corrosion. It is stronger and more durable.

Types of welded mesh

The production of welded mesh involves several options for the production of finished products. It is possible to purchase welded mesh in the following formats.

Welded mesh in roll

Welded mesh in a roll has maximum flexibility, which allows it to be rolled into rolls due to the smaller wire diameter. Due to the fact that welded mesh in rolls allows for quick installation and also meets many requirements and construction standards, this material is often used for the construction of fences.

You can view the welded mesh in rolls available for sale or compare them here.

Welded mesh in cards

With this option, the welded mesh is made in a rectangular shape. The diameter of the wire used here is larger, so the rigidity is higher.

The grid in maps is often used at various stages of construction:

When pouring the floor. In order to prepare rough and finishing bases in the form of a floor screed, reinforcement is necessary; this is where welded mesh is used, which is an inexpensive and durable material. When laying building blocks and bricks. We are talking about building houses. Here it is customary to reinforce every fourth row using 8 mm reinforcement or masonry mesh, which is selected according to the thickness of the block. It is easier to work with masonry mesh, the wire diameter of which is 1.6-1.8 mm, since it is equally suitable for both glue and cement mortar. During road construction. The use of welded mesh allows you to increase the strength of concrete and paths on the territory of private houses.

Masonry nets

Reinforced mesh for masonry walls or masonry mesh is used in construction as a reinforcing element when creating reinforced concrete structures, erecting walls, pouring floors and foundations to strengthen the structure. The use of masonry mesh allows you to increase the strength of the wall without increasing its thickness. The reinforced mesh with high tensile strength can be bent without damage, and also has anti-corrosion properties and a long service life.

Expanded metal mesh TsPVS

All-metal expanded metal mesh (TSPVS) is a metal sheet, evenly cut and stretched into diamond-shaped, staggered cells. Cold-rolled sheet metal with a zinc coating is used for the manufacture of CPVA. TsPVS mesh is a relatively new material on the market, but has already established itself as a cheaper analogue of chain-link mesh and welded wire mesh. The TsPVS mesh is easy to cut, has a lower specific gravity, and is visually aesthetic. TsPVS meshes are used for:

1. Reinforcement when performing plastering work.
2. Reinforcement when laying tiles, stone and similar building materials.
3. Reinforcement during facade work and application of thermal insulation coatings.
4. Fencing garden plots, making cages for pets.
5. Production of screens for heating radiators and ventilation grilles.
6. Manufacture of fencing for electromechanical devices, thermal insulation of pipes.
7. Guards for bins, trailers, conveyors, etc.
8. Cutting off concrete at the stage of roof installation.
9. In interior design.

The special shape of the TsPVS mesh gives it rigidity, and the absence of welds eliminates the presence of vulnerable areas in which the process of structural destruction begins. Due to its shape, moisture and foreign contaminants do not accumulate in the mesh fabric, which eliminates the appearance of pockets of corrosion.

Welded mesh with PVC coating

PVC coated welded mesh with plastic coating is made of high quality galvanized iron wire. A smooth plastic coating is attached to the anti-corrosion coating using strong adhesive, which increases the service life of the wire. Welded mesh with PVC coating is used for fencing residential and public buildings, such as gardens, parks, and other buildings. You can buy PVC-coated welded mesh in the form of rolls and panels, as well as in various colors.

Galvanized Welded Mesh

Galvanized Welded Mesh
Galvanizing can occur either before or after the fabrication of wire mesh in either woven or welded form. After welding or weaving is completed, the mesh is immersed in a bath of molten zinc. The zinc bonds to the surface of the wire, thoroughly sealing it and protecting it from rust and corrosion. This can be done using electroplating, which uses electricity to bond the zinc to the underlying metal wire, or hot-dip, which involves immersing the product in a galvanizing tank full of molten zinc at a temperature of around 450 C.

One of the main advantages of galvanized wire mesh is that it offers a wide range of hole sizes and wire diameters. It is used on wire mesh for various applications of the finished product. From landscaping a fence to a heavy industrial area

Welded Stainless Steel Mesh
