Rolled metal as a product of the metallurgical industry is currently in wide demand in completely different fields of activity - from industrial production to construction. Rolled metal is produced by cold or hot rolling. Rolling is the most widespread type of metal forming by pressure, which consists in squeezing a workpiece with two or three rolls (rollers) rotating in different directions. The friction force pulls the workpiece into the gap between the rolls and stretches along its length, forming the profile of the finished product.
There are 3 main types of rolled metal: sheet, section and pipe.
Sheet metal is metal obtained in the form of smooth or corrugated sheets of various thicknesses. This type of rental includes sheets for various purposes: for the creation of fences and roofs, the manufacture of car body panels and ship skin.
Tubes are products in the form of pipes of various shapes, lengths and diameters. Pipes can be welded or seamless.
Long products , in turn, is divided into simple and shaped. Simple long products have a simple geometric shape in their cross-section. This type includes beams, circles, squares, construction reinforcement, wire and other products. Shaped is rolled metal, the cross-section of which forms a certain figure. The products obtained in this way are divided into general and special purpose products. General-purpose structural shapes include T-beams, I-beams, angles, channels, etc. Special shaped rental is, for example, tram and railway rails.

Rolled metal is produced by hot and cold rolling. The hot-rolled method is a type of rolling of metal heated to 1000-1300 degrees Celsius. The cold-rolled method does not provide for heat treatment of the metal.
In modern construction, rolled metal is used mainly in the form of smooth or profiled sheets (corrugated board) for the manufacture of roofs, temporary barriers, cladding of buildings, and also as reinforcement. The armature is widely used for reinforcing (strengthening) concrete products (beams, floors, staircases, etc.) and for pouring foundations for construction. Today, the most demanded in this regard are: A1 class smooth round reinforcement and A3 corrugated round reinforcement made of low-alloy carbon steel. It is these two types that make up the basis of the reinforcement mesh.
