HRB400 HRB500 Hrb500e Deformed Steel Rebar 6-50mm Diameter for Construction Reinforcement
Rebar (reinforcing bar) is a steel bar used as a tension device in reinforced concrete and masonry structures to strengthen concrete under tension. Concrete exhibits strong compression resistance but low tensile strength, making steel reinforcement essential for structural integrity.
