The steel supplied in coils is not subject to twisted or wrinkled ends.

In some places, curved edges under the cut of a little more than 90 degrees are allowed.

Curved edges under the cut of more than 90° are allowed in certain places.

The lower mass fraction of carbon should not be separated. For rolled steel with grade numbers 3, 4, 5 (all stages of deoxidation), a reduction in the mass fraction of manganese by 0.10% is allowed.

When acidifying steel with aluminum, titanium or other deoxidizing agents, do not replace silicon, as well as with any deoxidizing agents (ferrosilicium and aluminum, ferrosilicium and titanium etc.) the mass fraction of silicon in steel is allowed less than 0.05%.

  • sheet steel - in 6 categories: 1-5 for hot-rolled mills, 6 for hard-rolled mills.
  • thin sheet - into 5 categories.

For rolling accuracy: A - advanced accuracy;

B – normal accuracy.

By flatness: - especially high flatness, PV - high flatness, PN - normal flatness. For finishing the surface on the group: III - advanced exacerbation, IV

- Primary training. A sheet of low-grade hot-rolling is prepared quickly and easily..

4-60mm Depending on the type of metal products and materials, hot-rolled low-alloy sheets are produced from steel grades:.

09G2, 09G2S, 09G2S-12, 17G1S, 17G1SU, 10HSND

Vikorist is used for welded, riveted or bolted structures in buildings, especially without additional thermal treatment.

Hot-rolled structural aluminum sheet is supplied in the form of sheets, rolls, and is divided into:

Chemical steel warehouse confirms: Complies with standard characteristics hot rolling sheet prepare 3
