Cold-rolled ribbed steel structure design elements: as specified shear reinforcement. Seismic house height should be higher than the current maximum applicable national standard "design of concrete structures." Shear wall of reinforced configuration CRB600H, its distribution muscle of the minimum reinforcement ratio, axial compression ratio, bound edge components and set the edge member structure should be consistent with current national standard "Design of Concrete Structures" requirement. Cold-rolled ribbed steel base material: cold-rolled ribbed steel bars should give priority to high-speed control without twisting wire. Studies have shown that CRB600H manufacturers, Q235 base material in cross-sectional reduction rate the indicator 20-30% CRB600H wholesale, strength and elongation can LL550 cold-rolled ribbed steel bars. In addition to cold-rolled ribbed steel wire rod rolling ФR7 suitable Ф8 outside CRB600H company, the remaining co-sectional size of the compression rate is too large, resulting in high product strength, and elongation of less than 8%. CRB600H wholesale, Ding Ding cold-rolled (certified), CRB600H by Ding Ding Industrial Co., Ltd. of Henan Province. Henan Ding Ding Industrial Co., Ltd. (www.hnddsy.com) is Anyang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Ding Ding cold rolling in leadership with the staff warmly welcome all inquiries negotiations to create a better future for cold-Ding Ding.
