OREANDA-NEWS. August 17, 2011. Ba Yi iron & steel Co.,Ltd. has developed 3 level,4 level,5 level hot rolled ribbed steel bar which has good performance of anti-seismic. It is a promotion for Xin Jiang to accelerate using high strength anti-seismic steel bar, reported the press-centre of Baosteel.

Compared with normal steel bar, high strength anti-seismic steel bar not only save the steel material and reduce self weight of construction but also effectively improve the anti-seismic performance of concrete and project quality, it has a high cost performance. From First of July this year, our country introduce newconcrete structure design standard, it demand building operations should prior to use 400Mpa steel bar (4 level), actively spread 500Mpa (5 level) steel bar. At the same time, it demand use high strength steel bar for bearing structure for example girder, column etc.
 
Recently, Ba Yi iron & steel strengthen research and development of high strength anti-seismic steel bar. On the base of original normal hot rolled ribbed steel bar, add a number of micro-alloy reasonably and scientifically. The product mechanical property of stability, toughness and weldability accord with technical standard completely.
