ZD-HRR High Strength Steel Rebar HRB335/400/500 Grade 8-50mm Diameter for Construction Applications
Rebar (hot-rolled ribbed steel bar) features surface ribs that significantly improve bonding capacity with concrete, making it ideal for reinforced concrete structures. The grade designation HRB indicates Hot-rolled Ribbed Bars followed by the minimum yield point.
- Available in multiple grades: HRB335, HRB400, HRB500, and seismic variants (HRB400E)
- Nominal diameters: 8-50mm (standard sizes: 8, 12, 16, 20, 25, 32, 40mm)
- Transverse rib patterns: spiral, herringbone, or crescent
- Superior tensile strength for reinforced concrete applications
