[本刊讯]日前,住房和城乡建设部、工业和信息化部正式发布《关于加快应用高强钢筋的指导意见》(以下简称《指导意见》),要求“十二五”期间,在建筑工程中加速淘汰335MPa级螺纹钢筋,优先使用400MPa级螺纹钢筋,积极推广500MPa级螺纹钢筋。《指导意见》明确了加快应用高强钢筋的路线图,要求在2013年底,在建筑工程中淘汰335MPa级螺纹钢筋;2015年底,高强钢筋的产量占螺纹钢筋总产量的80%,在建筑工程中使用量达到建筑用钢筋总量的65%以上。
Recently, the Ministry of Housing and Urban-Rural Development and the Ministry of Industry and Information Technology formally released the Guiding Opinions on Accelerating the Application of High-Strength Reinforcing Bar (hereinafter referred to as Guiding Opinions), requiring that during the “Twelfth Five-Year Plan” In the construction project, the steel bars of 335MPa grade should be eliminated quickly, the 400MPa grade of threaded bars should be used first, and the 500MPa grade of threaded bars should be actively promoted. The Guiding Opinions set out a road map for accelerating the application of high strength steel bars and required the elimination of 335MPa grade rebar in construction work by the end of 2013. By the end of 2015, the output of high strength steel products accounted for 80% of the total output of rebar and was used in construction projects Volume reached 65% of the total amount of construction steel.
