GB50010-2010《混凝土结构设计规范》中，HRB 500 （Hot -rolled Ribbed -Steel Bar）中文名是热轧带肋钢筋，旧称四级螺纹钢筋，屈服强度不小于500Mpa，横截面通常为圆形，且表面带肋的混凝土结构用钢材。 GB/T 1499.2-2018《钢筋混凝土用热轧带肋钢筋》中，钢筋按屈服强度等级分为400、500、600Mpa级，按生产控制状态分为 热轧钢筋 和控轧细晶粒钢筋两个牌号系列 …

2024年4月18日 · Anti-seismic hot-rolled steel bars, specifically HRB500, represent a class of engineered reinforcement materials designed to fortify structures against seismic shocks.

2020年4月30日 · In this research, extensive testing results of the specimens of HRB500 high-strength steel rebars joined by flash butt welding were demonstrated, including metallographic and micro-hardness tests, monotonic tensile tests, …

This brochure explains how using high performance concrete (HPC) together with high strength HRB500 rebar can significantly reduce the carbon footprint of new buildings. This approach provides urban planners and construction companies with a solution to meet the demand for greener buildings, as countries aim to reach net zero targets.

Explore the key features and specifications of HRB335, HRB400, and HRB500 steel bars, essential for concrete reinforcement in large buildings, bridges, and tunnels. Learn about their diameter range, standard lengths, allowable deviations, and common spec.

HRB500 steel reinforcement refers to a commonly used steel material in concrete structures, which has certain strength and toughness, and can effectively enhance the bearing capacity and tensile performance of concrete.

The common brands of hot rolled ribbed steel bars are HRB400, HRBF400, HRB400E, HRBF400E, HRB500, HRBF500, HRB500E and HRB600. HPB300 (Grade I) is a common steel bar with a diameter of 6-12mm. Commonly used in the production of stirrup, wall reinforcement, etc. HRB335 (Grade II) is a threaded steel with a diameter of 12-25mm.

HRB500 deformed bar . Product Description. Reinforcing steel bar is produced by hot rolling process with subsequent superficial hardening by heat treatment. Commonly, it is supplied in length of 6 m to 12 m. According to the surface treatment, it can be classified into plain bar and deformed bar. Plain bar is often used in situations where the ...

HRB500 deformed steel bar is commonly used for beams, columns, shear walls in large and medium-sized concrete structures. HRB500 deformed steel bar can also be used for small-scale construction projects such as housing, bridges, roads.
