HPB500 is a Chinese national standard hot-rolled plain round reinforcement rebar with a specified yield strength of 500MPa, the top-grade plain round rebar in the HPB series. It surpasses HPB400 in tensile and yield strength by a large margin, while retaining excellent plasticity, ductility and reliable bonding performance with concrete. It features workable weldability and cold workability for on-site processing, with a full range of standard diameters, stable mechanical properties and high structural safety. It’s a high-cost-performance high-strength core material for high-load and large-scale construction engineering.
