Hot Rolled Reinforced Steel Rebars HRB400 HRB500 6-50mm Deformed Bar for Construction
Rebar (reinforcing bar) is a steel bar used as a tension device in reinforced concrete and masonry structures. Concrete has excellent compressive strength but low tensile strength, making steel reinforcement essential for structural integrity in buildings, bridges, roads, and foundations.

Fine-grain hot-rolled steel bars (HRBF series) provide enhanced mechanical properties. Seismic-grade reinforcement (HRB400E, HRBF400E) meets higher structural requirements for earthquake-resistant construction.
Comprehensive stock of rebar in diameters 6mm to 50mm. Orders up to 10,000 tons can be packaged and shipped within 3 days. Export standard lengths of 6-12 meters available.
Strict surface quality standards: straight-cut ends, free from cracks, scars, and folds. Maximum bending tolerance of 0.4% of total length ensures optimal performance in concrete structures.
Highest demand for 8mm, 10mm, and 12mm diameters in general construction. Increasing demand for 14mm and 16mm diameters in large-scale infrastructure projects.
