Rebar into hot-rolled ribbed steel bars and cold-rolled ribbed steel. Cold-rolled strip straight through experiments twisted steel from the yield strength, tensile strength, elongation, cold conditions, and other mechanical properties of the standard description of the twisted steel cold-rolled, cold-drawn and twisted steel and mechanical properties were compared, results cold rolled rebar has high strength, good ductility, good anchorage performance and mechanical properties of strong cold-rolled ribbed steel bars, etc. Applications: admission test cold-rolled ribbed steel rebar spot straight through inspection after before use. For visual quality inspection before cold rolling straight rebar prices, cold-rolled ribbed steel test surface shall not damage or other defects affect the use of; then rolled flat measuring its thickness, pitch, weight bias; finally each Batch cold-rolled ribbed steel bars randomly selected three, with two tensile test, a cold bending test. Through experiments, cold-rolled ribbed steel bars, batch tests are in line with regulatory requirements. Cold rolled straight twisted steel factory | Dingding cold rolled | Jiangxi cold rolled straight twisted steel provided by Ding Ding Industrial Co., Ltd., Henan Province. Ding Ding Industrial Co., Ltd., Henan Province (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.
