"

The sheet of steel is divided into:

according to the method of production

hot-rolled sheet (GC)
cold-rolled sheet (ХК)
in thickness

from 0.35 to 3.99 mm - sheet steel
from 4 to 160 mm - thick sheet steel
by rolling strength(//tractor-service.com)
of increased accuracy — A,
normal accuracy - B
by flatness
especially high flatness — PO
high flatness — PV;
of normal flatness — PN
according to the nature of the edge
with an uncut edge - NO;
with a cut edge — O).
In the case of a hot-rolled steel sheet, the metal is heated, and then deformed with the help of special presses and rolled. In order to achieve a uniform thickness of the product, it is subsequently subjected to cold rolling, which significantly increases its properties.
Steel sheet is widely used in mechanical engineering, construction and other industries.
