我国是钢铁大国,去年钢产量达到7亿多吨,实际产能10亿多吨,可是用于建筑的钢结构却不到5%。钢结构具有抗震性能好、建设速度快、钢材可回收利用的特点,这也符合当前绿色建筑的要求,但在民用建筑中却得不到很好应用,造价较高是其直接原因。钢结构住宅的难点在墙板,对此很多企业都不愿意去接触,不去研究开发或与板厂进行战略合作,从质 China is a big steel country. Last year, its steel output reached 700 million tons and the actual production capacity was over 1 billion tons. However, the steel structure used for construction was less than 5%. Steel structure with good seismic performance, construction speed, steel recyclable features, which is also in line with the current requirements of green building, but not well used in civil construction, high cost is the direct cause. Steel housing difficulties in the wall, which many companies are reluctant to contact, not to research and development or strategic cooperation with the MILL, from quality
