Shaped rolled products and their use in construction

What is shaped steel

First of all, shaped rolled products are products of the metallurgical industry, produced at large metallurgical enterprises.

Machines for the production of shaped metal products are called rolling mills. They are quite impressive in size and the products produced on them are of impressive length. Commercial rolled products are cut into lengths from 6 to 12 meters.

Secondly, there is a complex spatial definition of shaped metal products, with tangents to the surface that intersect at points, etc. In real life, it is very easy to distinguish shaped steel from other metal products. In cross-section, it has a complex geometric shape different from a circle and a square, without a closed perimeter.

Types of long products

Long products can be simple or shaped.

Simple bars

This rolled metal is divided into several categories depending on the quality of the surface:

• Ready for use without processing.
• Designed for heat treatment under pressure.
• For processing by mechanical means.

Simple rolled products include metal elements that have an elementary cross-sectional shape without a cavity.

Assortment of simple long products:

• Steel square. A rod with a square cross-section. Used to create various precise designs. Carbon or alloy steel is used for production. Sizes vary from 6 to 200 mm.
• Steel circle. The most popular product of this line. The rods have a round cross-section, the diameter of which ranges from 5 to 200 mm. Rolled products are made from low-alloy and carbon steel, less often from high-alloy steel. Products are used in various industries: heavy engineering, construction, shipbuilding, in the production of fences, nets, fittings, for forging.
• Steel hexagon. A rod of hexagonal cross-section with equal sides. Made from carbon or alloy steel. Serves as a semi-finished product for the manufacture of fasteners, hardware, and screws. It is also used in construction, for the manufacture of household and industrial equipment, machine tools, in the food, automotive, and engineering industries.
• Steel strip. Rental of all sizes with a rectangular cross-section. Produced using hot rolling or cold deformation technology. The product is used to produce various parts; it can act as a blank for the production of tools, and as a basis for complex structures.
• Wire. Produced using hot or cold drawing methods. The cross-section can be round, square or oval. Raw materials for production: cast iron, nickel, low-carbon steel, titanium, aluminum, copper, zinc, nickel. Spring types are used for the manufacture of shock absorbers, springs, fasteners, and nails. Knitting - for fastening parts, blanks, reinforcing reinforced concrete structures.

What is classified as shaped steel?

You can view shaped and long products in the catalog on the website https://www.maxima-metall.dp.ua/. The following metal products are classified as shaped rolled products:

Corner: a product made in the form of a real corner with shelves of different widths. In the construction of a house it is used everywhere, from tying the foundation to grounding;

Channel: the cross-section of the product is similar to the letter “P”. In the construction of a house it is used as a supporting element in ceilings, door and window openings;

I-beam: This product is somewhat similar in cross-section to the letter “H” or an exact copy of the Roman unit. Due to its cross-section, the I-beam is tens of times stronger than square long-rolled pipes. The disadvantage of the I-beam is its low resistance to torsion, which does not prevent it from being widely used for beams of buildings and structures.

Taurus: a product with a profile in the shape of the letter “T”.

Rail: A product from the second group of shaped products, NOT general, but for special purposes. I hope the purpose of the rail does not require any comments.

Zet rolled: a profile in the cross section of which we see the letter “Z”. Used for the production of complex beams, such as the center beam of a carriage frame.

Application of simple long products

Rolled steel products are used in all areas of human activity. Without it, many technological processes and productions are impossible. It is used to produce shafts, gears, axles, fasteners and other types of parts and mechanisms. It is used to make blanks for other metallurgical products and forgings.

Shaped products

This type includes long hollow metal elements. They are in demand in civil and industrial construction, as well as in almost all areas of industry and production. The cross section of the products has a solid non-convex geometric figure.

Assortment of shaped rolled products:

Corner profile. L-shaped steel profiles with equal or different sides. They are used in construction for the construction of various structures, as well as strengthening walls and ceilings. The material is also used in the engineering industry, in the construction of carriages and ships.

Steel channel. Rolled products with U-shaped profile. Its main side is longer than the sides. Used to create frames and structures, for covering roof purlins. It is often combined with concrete to create durable structures.

I-beam Beam profile with H-shape. Available in standard, wide-shelf and column versions. The edges of the shelves can be parallel or inclined. Characterized by high strength. I-beams can withstand very high vertical and horizontal loads. Carbon, low-alloy steels are used for manufacturing. It is used in the construction and installation of overhead tracks, shafts, bridges, balconies. The products bind and strengthen structures and are used as a basis for door and window openings.

What is rolled metal made of?

Various types of steel and alloys can be used in its production. These include:

• carbon steel or so-called ferrous metal;
• alloy steel, the strength and performance characteristics of which are improved by adding various chemical components;
• stainless steel;
• aluminum;
• copper;
• tin.

This is not a complete list of materials used in the manufacture of rolled metal. A huge selection of metals and forms of manufactured products allows them to be used in a wide variety of industries. Parts of any shape can be made from this material, ensuring their resistance to any loads and temperature conditions.

Both long and shaped metal products are used in almost all industries. However, their difference lies in the fact that the high-quality type is used as blanks, including for the production of shaped types.

Distinctive features

Rolled metal is made from various steel alloys. It is divided into two main types:

• shaped;
• long products.

How are they different? In simple terms, the shaped type includes hollow metal elements. This means that in cross section they have a solid non-convex geometric figure. Prominent representatives of this variety are corners, channels and profiles. The varietal type includes metal elements that do not have a cavity. That is, they are convex in cross section. You can imagine rolled metal products by looking at a metal rod.

Shaped metal products and their use

Rolled steel is a concept that is often used in metallurgy. In the general sense of the word, these are products that are obtained using cold, warm or hot rolling. Rental products are divided into types depending on their characteristics. According to the profile - cross-sectional shape, sheet, long, pipe and shaped products are distinguished.

Rolled metal products are those metal products that are made by rolling a heated metal billet, and heating occurs to a certain, predetermined temperature, depending on the type of metal used.

By definition, shaped products are those where the tangent to at least one point of the perimeter will intersect the cross section.

As a rule, shaped steel has more complex profiles, in particular, angles, channels, beams, special-purpose profiles used in the automotive industry and in the creation of roads are classified as shaped steel.

According to their purpose, shaped metal products are divided into two types:

• mass-use - channels, corner profiles, I-beams, etc.;
• special purpose - railway rails, tram rails, profiles for mechanical engineering, electrical and oil industries, for shipbuilding.

Shaped metal products are essentially one of the types of rolled steel. For its manufacture, three different types of steel can be used - standard steel, low-alloy steel or carbon steel. In particular, popular options are ST3SP, ST3PS-5, 09G2S, as well as low-alloy steel grades 10KHSND and 15KHSND.

Overall dimensions are determined by the length of the rolled product and the volume of the bundle or pack into which the individual elements are combined (as a rule, everything is determined by their weight, which can be 5-8 tons).

These types of products are mainly used in construction and the automotive industry. They are used for laying tram and railway tracks and for decorative purposes.

Shaped products can be divided into large, medium and small sizes. At the same time, large and medium sizes are used for the construction of large industrial and commercial buildings, roads, overpasses and bridges that require higher strength of the load-bearing parts of the structure.

Small shaped rolled products are used for the same purposes in low-rise construction and to create metal structures for industrial and commercial, as well as domestic purposes (for example, doors, hangars, shelving, etc.). The demand for rolled products of this type is determined by the fact that in design and construction it is often necessary to have stiffeners in the material itself. This allows you to significantly simplify the design while maintaining its margin of safety. Often such structures are used as supporting or load-bearing

Shaped metal products include channels, angle steel and I-beams. A channel is a final rolled product made of metal. These products can be bent or hot-rolled, depending on the method of their manufacture. Hot-rolled shaped steel is made from regular and high-quality carbon steel, and from low-alloy steel. Bent steel products - from hot-rolled or cold-rolled steel, of ordinary production, or from low-alloy or structural carbon steel.

Hot-rolled channels are made from hot billets on special section machines. They are marked accordingly in shape and size: U - with slanted internal edges, P - with parallel edges, E - economical, L - lightweight and S - special, intended for specific purposes, used in the automotive industry and carriage building.

Bent channels are made using profile bending machines. They differ from hot-rolled ones in that their outer corner is slightly rounded. Channels marked A - high accuracy, B - increased accuracy, C - normal accuracy. The channel number is equal to its height. The production of this type of shaped metal products is strictly controlled. Tests of mechanical and technological type, and chemical analysis are used as control methods.

Metal corner (angular steel) is used for the manufacture of building structures, as a strength or decorative element. It is also used in mechanical engineering, in home life, and in construction. Manufactured in lengths from 4 to 12 meters or upon special order. There are equal and unequal angles.

An I-beam is a special product that is used for the manufacture of racks, columns, bridges, supports, frames of buildings and structures, and overhead tracks. The size of the beam is determined by the distance between the outer edges of the shelves.

Rails are products made from shaped metal products, which are used for the manufacture of link and continuous railway tracks, as well as turnouts. Produced strictly in accordance with government standards.
