Severstal Develops Reinforcing Bars of A800R Class

Russian steel maker Severstal, a Metal-Expo regular exhibitor, has developed and mastered the technology for the production of reinforcing bars of the A800R class with requirements for stress relaxation.

The fittings have successfully passed the certification according to GOST 34028-2016 at the Research Center Construction. Now, Severstal's product portfolio includes both standard reinforcing bars, A240, A400 and A500, and reinforcing bars with exceptional characteristics: A500SNU, reinforcement with increased ductility, enduring multiple cyclic loads; Armanorma, reinforcement of A600C class of increased strength, its properties up to minus 100 degrees as well as a new class A800P with requirements for stress relaxation.

A800R-class rolled steel is produced on mill 250 in the section rolling production of the Cherepovets Metallurgical Plant. Such reinforcement has high strength and bending resistance. Due to these characteristics, the product is suitable as a component of complex, including dimensional, structures that are subjected to heavy loads, as well as for the manufacture of prestressed reinforced concrete structures. The corrugated surface of reinforcing bars is made in the form of a sickle-shaped profile, which ensures excellent adhesion and connection with hardening concrete, and, consequently, high strength and solidity of structures.

Rebar A800P can be used for reinforcing prestressed reinforced concrete structures in industrial, special, hydraulic engineering and civil construction. For example, in the construction of bridges with wide spans, pressure pipelines, dams, watertight containers.

Severstal welcomes all steel industry professionals to visit its stand at Metal-Expo'2020, the 26th International Exhibition, November 10-13, Hall 57, VDNHa, Moscow, Russia. Stand N 2D10.
