Flat products are a separate type of metal products, used in various spheres of construction and industrial industry, they are easy to store and transport. Sheet rolled metal is suitable for the production of channels, corners, stripes and other elements.
Methods of steel production
Hot rolled sheet metal . It is obtained by rolling a heated metal billet through special equipment. This type of rolled steel is the cheapest, at the same time of high quality, resistant to rust and mechanical damage. These products are suitable for outdoor structures.
- thin, produced in the form of a roll, no more than 4 mm thick, is processed by etching;
- thick from 4 to 160 mm thick;
- low-alloyed, used in construction and in the field is made of low-alloyed alloys;
- structural, often used in mechanical engineering, made from alloyed carbon alloys.
Cold-rolled sheet products. It is made by rolling from ductile steel alloys. The scope of application of these products is not so extensive, the thickness of the product is not more than 12 mm. The main characteristics are: strength, minimum resistance, stretch. It is widely used in the automotive industry, corrugated board and other products are made from it.
Corrugated, galvanized sheet metal and corrugated sheets can be distinguished separately.
They have a surface stamped most often in the form of rhombuses on both sides or only on one side. Available in rolls. Used to increase friction as a floor covering, as well as in the form of cladding and ventilation panels.
This is a type of cold-rolled steel with a thick zinc layer applied to protect it from corrosion. The main features are:
- UV resistance;
- high temperatures;
- anti-corrosion properties;
- long service life;
- relatively low price.
Such sheets are in demand in construction (building cladding, roof installation), medicine, food industry.
Produced are manufactured by cold-rolled method in the form of a wave. They are used in construction for roofing works, wall cladding, in the form of fences, as a component of sandwich panels.
When choosing the right sheet, you need to decide on the scope. In terms of quality, galvanized sheet of cold-rolled steel wins. The hot-rolled sheet is not so even with variations in thickness, it has dross. At the same time, its cost is much lower, if the disadvantages do not affect the result of application, this type of rolled product can be safely used.
