HRB335 HRB400 HRB500 Hot Rolled Deformed Steel Rebar 6-50mm Diameter for Construction and Infrastructure Projects
Rebar (reinforcing bar) is a steel bar used as a tension device in reinforced concrete and masonry structures to strengthen and support concrete under tension. Concrete has excellent compression strength but low tensile strength, making rebar essential for structural integrity.
