ASTM Standard HRB335 HRB500 Deformed Steel Rebar 6-90mm Diameter for Construction Projects
Rebar (reinforcing bar) is a steel bar used as a tension device in reinforced concrete and masonry structures to strengthen concrete under tension. Concrete has excellent compressive strength but low tensile strength, making rebar essential for structural integrity in construction projects.
Manufactured from carbon steel with ribbed surfaces for enhanced friction and bonding with concrete, our rebar prevents crack formation and propagation in foundations, walls, driveways, and patios.
