Industrial Structural Steel Shapes | ASTM A6/AISC Certified

Structural Steel

Hot-rolled structural steel shapes—such as channels, I-beams, H-sections, equal and unequal angles, flat bars, square bars, round bars, hexagonal bars, and heavy girders—are fundamental components in modern construction and industrial engineering. Manufactured from high-quality carbon and low-alloy steels (e.g., Q235B, Q355B, S355JR, A36), these profiles offer excellent mechanical strength, dimensional stability, and weldability.
