Cold rolled ribbed steel theoretical weight, Ding Ding Industry (certified), Jiangsu cold rolled ribbed steel provided by Ding Ding Industrial Co., Ltd., Henan Province. Ding Ding Industrial Co., Ltd., Henan Province (www.hnddsy.com) is a professional enterprise, "cold-rolled ribbed steel CRB550", the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Liu. The new cold-finished production line equipment went into operation in 2008 in Anyang, the corresponding national standard GB13788-2008 also released at this time. Unlike the new cold-rolled ribbed steel cold-rolled ribbed steel cold rolling past ribbed steel, the new production line has tempered steel cold rolled ribbed steel production, product strength, ductility and yield point have increased. The new production line factory steel cold rolling ribbed steel production line, its strength has reached 550MPa. Cold-rolled ribbed steel installation: site should be strongly avoided protective layer pads and steel bracket installed cold-rolled ribbed steel bars artificially hit stampede and mechanical pressure, because of the deformation capacity is limited, once the damage ribbed steel cold rolling mill , even if the surface restoration, will reduce its physical properties and durability. On-site storage, processing and installation of lashing and other construction process should take rain, snow measures to prevent cold-rolled ribbed steel bars by washout.
