STRUCTURAL ROLLED PRODUCTS

Structural rolled products from carbon steel

Under to ASTM A570/A570M

Rolled sheets and coils are manufactured of carbon structural steel of grades G30, G33, G36, G40, G45, G50, G55 and are used for

metalwork fabrication.

The thickness of rolled products delivered is 1.5 till 6.0 mm. Dimension tolerances take into account the requirements of standards

А568/А568М and А749/А749М.

Steel can be produced either by BOF or by electric furnaces.

Under ASTM A607

Rolled products of high-strength low alloy steel with addition of niobium or vanadium (or combination of the same). These rolled product

are used where moderate weight and higher strength are of importance.

Rolled products are delivered in the form of coils or sheets cut to length.

Under ASTM A715

Rolled products of high-strength low alloy steel with improved stamping ability. The products are used in construction and other fields of

application where high strength, minor weight, improved stamping ability and weldability are of importance. The products are manufactured

in the form of sheets and coils.
