Ribbed cold drawn steel production line _ Ding Ding Industry (certified) _ Shandong cold drawn steel ribbed 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. Cold-rolled ribbed steel intensity level roughly the same countries, both in the upper and lower 550Mpa cold drawn steel ribbed construction specifications 4─9mm. For ordinary reinforced concrete structures, such as pouring the slab, foundation slab of ribs and distribution muscle force, shear distribution ribbed steel cold drawn bars, stirrups and other beams. Mechanical properties of reinforced international standards ISO10544─1992 (E) provides as follows: yield strength 500Mpa, tensile strength 550Mpa, elongation (gauge 5 times the diameter) of 12% (Note: My elongation set δ10≥ 8% instead δ5≥12%). The biggest advantage is the high-strength cold-rolled ribbed steel cold drawn steel ribbed wholesale, and with the concrete has a high strength adhesive anchor, anchor member ends to reduce the length of only about 1/3 of smooth steel, so smooth steel Some quality problems due to poor performance bond anchoring produced radically improved. Compared with the traditional forms of steel, after use can save a lot of reinforcement. Cold-rolled ribbed steel suitable for large-scale use in cast concrete panels.
