Cold-rolled ribbed steel craft, Ding Ding Industry (certified), Shandong, cold-rolled ribbed steel bars supplied 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 hot-rolled plate, as amended, with multi-channel cold-rolled ribbed steel reducing size, a pressure ribs and internal stress by eliminating the formation of a post with two or three sides of the crescent-shaped surface reinforcement. Cold-rolled ribbed steel in prestressed concrete components in cold-rolled ribbed steel bars, cold drawn carbon steel wire is replacement products, in-situ concrete structures in cold-rolled ribbed steel use, you can substitute Ⅰ grade steel to save steel, are similar in a good kind of cold steel. Mechanical properties of cold-rolled ribbed steel bars, largely depends on the chemical composition and mechanical properties of the base metal, cold-rolled ribbed steel cold-rolled ribbed steel weight, should give priority to high-speed control without twisting the wire, because it's chemical composition and mechanical properties is relatively stable, cross-sectional dimensions of consistency is also very good, as between the mechanical properties of the base material after the compression ratio to determine the cross-section and cold-rolled ribbed steel bar exists a good correlation, ie the greater the compression ratio, finished higher the intensity, and lower elongation.
