为落实国务院节能减排工作部署,近日,住房和城乡建设部、工业和信息化部联合出台了《关于加快应用高强钢筋的指导意见》(以下简称《指导意见》),明确提出了在“十二五”期间加快应用高强钢筋的主要目标: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。到2013年底,在建筑工程中淘汰335MPa级螺纹钢筋;到2015年底,高强钢筋的产量要占螺纹钢筋总产量的80%,在建筑工程中使用量要达到建筑用钢筋总量的65%以上。
In order to implement the deployment of the State Council’s energy-saving emission reduction work, recently, the Ministry of Housing and Urban-Rural Development and the Ministry of Industry and Information Technology jointly promulgated the Guiding Opinions on Accelerating the Application of High Strength Reinforcing Bar Steel (hereinafter referred to as Guiding Opinions) Twelfth Five-Year "to speed up the application of high-strength steel The main goal: to speed up the elimination of 335MPa grade rebar, priority use of 400MPa grade rebar, and actively promote the 500MPa grade rebar. By the end of 2013, 335MPa grade screwed steel bars will be eliminated in construction projects; by the end of 2015, the output of high-strength steel bars will account for 80% of the total output of screwed steel bars and the usage in construction projects will reach more than 65% of the total amount of steel bars for construction use.
