HRB400 HRB500 Carbon Steel Rebar 6-50mm Diameter Deformed Steel Bars for Construction Concrete
HRB400 and HRB500 carbon steel deformed rebar, also known as ribbed steel bars or iron rods, are essential construction materials designed for reinforced concrete structures in buildings, bridges, roads, and civil engineering projects.
Available in multiple grades including HRB335, HRBF335, HRB400, HRBF400, HRB500, and HRBF500. Seismic-grade variants (HRB400E, HRBF400E) are available for structures requiring enhanced earthquake resistance.
