Cold-rolled ribbed steel structure design elements: as specified shear reinforcement. No requirements for seismic reinforcement may be used as reinforced concrete shear wall buildings and seismic intensity of 6 degrees, 7 degrees and 8 degrees (C) of reinforced concrete building frame a wall structure, frame - supported shear wall structure and some scissors power distribution muscle wall structure shear walls. But the bottom level seismic level distribution of shear reinforcement should strengthen parts of hot rolled ribbed bar. Construction Points cold-rolled ribbed steel bars: cold-rolled ribbed steel bars typically bundles wholesale supply CRB600H straight length according to project needs, their mechanical properties and process performance should be approved sampling. Each batch should be the same manufacturer, same size, same sources of raw materials, the same composition of steel rolling production process, and not more than 10t. Each batch quality certificate of steel should be manufactured, each bundle should sign. Factory direct CRB600H, CRB600H, cold-Ding Ding Ding Ding Industrial Co., Ltd. by Henan. Henan Ding Ding Industrial Co., Ltd. (www.hnddsy.com) strong, credible, Anyang, Henan Province in other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Dingding cold rolled into the brilliant and you work for a better future!
