HRB500Ⅳ级是目前我国使用于建筑物的最高等级钢筋,以其强度高、延韧性好、碳当量低、屈服点高、抗拉强度高,易加工及良好的焊接性能等诸多优点,被逐渐应用于各种建筑工程,提高了建筑物的抗震性能,减少钢筋用量,起到了节约能耗、节约资源,减少排放的效果,也响应了国家节能、环保的政策具有巨大的社会效益和经济效益。
HRB500 Ⅳ level is currently the highest level of steel used in buildings in China, with its advantages of high strength, good ductility, low carbon equivalent, high yield point, high tensile strength, easy processing and good welding performance, etc., are gradually applied In a variety of construction projects to improve the seismic performance of buildings and reduce the amount of steel, played a saving energy, saving resources and reducing emissions, but also respond to the national energy saving and environmental protection policies have great social and economic benefits.
