High-strength thermo-mechanically treated bars for superior structural integrity and earthquake resistance. Manufactured using advanced Thermex technology for the perfect combination of strength and ductility.
Precision-rolled angles and flats for structural frameworks, towers, and industrial applications.
High-quality square and round bars for construction, fabrication, and industrial manufacturing applications.
Every GR Steels bar is engineered to deliver unmatched performance across critical construction parameters.
Superior ductility and high elongation ensure structures withstand seismic forces with ease.
Withstands temperatures up to 600°C without significant loss of structural strength.
Low carbon equivalent ensures easy welding without compromising joint integrity.
Thermo-mechanical treatment creates a protective oxide layer against rust and corrosion.
Precision rib pattern ensures maximum bond with concrete for stronger reinforcement.
Higher strength-to-weight ratio means 15–20% steel savings without compromising safety.
