Reinforcement steel grade, Steel Rebar, B500B & Bar Rolling Mill Process

Rebar

Weldable, sustainable reinforcing steel featuring improved bonding and high ductility, low carbon contents, packaged in bars, available in the range of diameters 8-32 mm, hot rolled and Water Cooled or Air Cooled (for Grade 40 and 60 ASTM 615).

Product characteristics

High bonding;
No axial torsion;
Reduced surface oxidation, giving greater weight yield and enhanced cleanliness.

Distinctive elements

Optimisation of production parameters in view of obtaining all products in class C - high ductility, guaranteeing:

Optimal mechanical properties for seismic and other applications;
Improved packaging for subsequent operations;
ICMQ ECO Gold sustainability label;
LEED credits;
Recycled content certification.

Chemical composition

The weldability of our rebars is guaranteed by the chemical analysis of the heats and the equivalent carbon content.
