Such popularity of metal rolling is explained by several reasons at once:
Despite the emergence of new materials, ferrous steel remains the most demanded product, while maintaining the perfect balance of cost and quality. Ferrous metal in a wide range is presented here.
Varieties of rolled metal
There is such a huge number of types of black rolled products that it is impossible to list them all. All diversity can be divided into several large groups:
It is also possible to single out stainless steel products as a separate group.
Rolled metal products are especially popular in the construction industry. Most often it is used for reinforcing reinforced concrete products and for mounting monolithic structures. The most popular types: corner, rod fittings, channels, pipes, etc.
rolled stainless steel.
Ferrous metal is produced from steel, cast iron, and their alloys. It is used in production where reliability and durability are required. Non-ferrous rolled metal is produced from aluminum, copper, tin, zinc, lead, brass, chromium, magnesium, nickel, etc.; as well as rare and precious metals. CJSC "Metallotorg" sells ferrous metal. Black rolled products are cheaper, but have greater strength and wear resistance than non-ferrous rolled products. Color is used in areas where its specific properties are required: in medicine, aviation, instrumentation, electronics or the space industry.
Ferrous rolled metal is used in the construction of buildings and structures, in mechanical engineering, aircraft construction, energy, and the chemical industry. Black steel is indispensable in instrumentation, carriage, transport and shipbuilding, in the laying of sewers, oil and gas pipelines. It is also used in building decoration, roofing, in the military industry, in the construction of mines, in the production of furniture, metal structures, concrete floors, panels, machine tools and much more. Not without metal rolling and the device of private, suburban facilities.
A person who is faced with rolled metal products, with construction or production, needs to know such terms as assortment and profile. The assortment of rolled metal is a set of rolled profiles that differ in shape and size. Rolled metal profile - the cross-sectional shape of the product.
Steel rolling is carried out in the following ways:
Ingots are used, which are heated and rolled on squeezing machines. All defects are removed from the metal surface, and then it is reheated and rolled.
In special machines, continuous casting is used, and then the metal is rolled, as in the first method.
Features of rolled metal
The material is becoming more and more in demand in the construction market. There are many production methods, for which non-ferrous metals and alloys are used. All manufacturing options are divided into cold-drawn and hot-rolled. It is on the choice of method that the future application depends.
The finished material has a number of advantages:
increased strength;
resistance to corrosion processes due to galvanized coating;
protection against mechanical impact;
long service life.
The main advantage of rolled metal products is the possibility of manufacturing structures that will have a long service life. They can be used together with concrete elements, and over time they do not have to be replaced with new ones.
How to choose quality material
Rolled metal is important to choose in accordance with the requirements of GOSTs and technical regulations. Finished products are subject to certification for the following parameters:
chemical composition of alloys and steel;
length, size and assortment;
compliance with technical conditions in the production process.
The production of metal products occurs due to a change in temperature. As a result, high strength and reliability of various items are ensured, including angles, channels, steel sheets.
Selection of steel sheets
The most requested steel sheets are as follows:
Smooth. The range is always in demand. The choice depends on the wall thickness.
Stainless. They are distinguished by resistance to ultraviolet radiation, elevated temperatures, and corrosion processes.
Perforated. Products receive holes of various shapes - square, rectangular, oval or round.
Galvanized. Among the positive properties, resistance to corrosion processes, ultraviolet radiation, and temperature extremes are distinguished. Sheets are distinguished by a relatively low cost, a long period of use. The material is indispensable if roofing work is required. It is also indispensable withoutsphere of industry and mechanical engineering.
Decorative. To date, you can choose options for different shapes, including mirror, corrugated, polished. It is also possible to give different textures.
Corrugated. This is a special product that is characterized by increased thickness. It is used for the construction of internal fences or sheathing the surface of walls.
The areas of application are different. They can be used in construction, economic and industrial activities. Coiled steel is used in the construction of industrial complexes, multi-storey buildings or during the start-up of machines. Steel products are required when certain types of furniture, automobiles and aircraft are produced.
Recently, decorative elements have become popular. They are indispensable if you need to make furniture, decorate a building or create a non-standard composition. Elements of non-ferrous and ferrous metal are in demand. Some models are used for fixing rails.
Thus, rolled metal has a wide scope of application. It is represented by a large selection of products in terms of shape, material, parameters, additional processing and purpose.
Sheet metal: features
Today, its demand has increased in the markets. There are many ways to make it. Mainly produced from alloys and non-ferrous metals. Distinguish depending on the method of production of products. It is divided into hot rolled and cold drawn. The scope of the sheet depends on how it is made. Such products are in demand in construction and industrial production. Steel plates are in the greatest demand. After all, they have a number of advantages:
strength;
long service life;
resistance to temperature extremes, mechanical influences from the outside;
due to the galvanized surface - corrosion resistance.
The product is manufactured by changing the temperature regime. The profile is deformed under the influence of cold or hot temperature. Popular types include the following:
Smooth. Always in demand. The assortment is wide, depending on the wall thickness.
Galvanized. Among the positive characteristics, it is worth highlighting the resistance to corrosion, exposure to high temperatures, ultraviolet radiation. The price of sheets is relatively low, and the service life is significant. They can be subjected to various treatments. Widely used in roofing, mechanical engineering and industry.
Perforated. They have holes of different shapes (round, square, rectangular). It can be used as a decoration for building facades or in construction.
Stainless. Products have many advantages: they are not subject to corrosion, resistant to high temperatures, plastic, durable and attractive in appearance. They are used in almost all spheres of life (railings, spans, commercial equipment).
Decorative. Today they are produced in various shapes (corrugated, mirrored, polished, textured).
Corrugated sheets. This is a special product having a good steel thickness. Used for wall cladding, for the construction of fences from the inside.

Main parameters and pipe profiles
The classification is based on several criteria. They are divided depending on the diameter, size, material of manufacture, connection method, type of insulation, profile cross section.
Kinds
Steel. The advantages of these products include a long service life (about 25 years) and reliability, the disadvantages are huge weight, lack of resistance to corrosion. They are made galvanized, welded, cold and hot rolled, cold drawn, profiled.
Galvanized. They are able to tolerate various temperature extremes. Not subject to corrosive influences. At a cost, of course, much higher than usual, but, on the other hand, they are several times better in quality.
Copper. Pluses are durability (the service life reaches 100 years), resistance to corrosion and high temperatures. Cons - high price, low strength, difficult installation.
Cast iron. Depending on the strength, there are black, gray and spheroidal graphite. Reliable, corrosion-resistant, but not so strong and costly during installation work.
Metal-plastic - made of plastic and metal. By far the most popular on the market. They have many positive characteristics: price, quality, ease of installation. The disadvantages include poor resistance to temperature extremes.
In addition, according to the method of application, the pipes can be:
