Cold-rolled ribbed steel Technical requirements: Grades and chemical composition. Manufacture of steel wire rod should be consistent with GB / T 701, GB / T 4354 or other relevant standards. Delivery Status: reinforced by cold state of delivery. Cryogenic tempering process allows cold rolling. Mechanical properties and process performance: When bending test, by the curved parts of the surface shall cracks. Cold-rolled ribbed steel Application: cold-rolled ribbed steel bars admission test, after inspection before use. First for visual quality inspection Buying 5.5mm cold rolled steel, cold-rolled ribbed steel surface inspection should not damage or other defects affect the use of; then rolled flat measuring its thickness, pitch, weight deviation; last in every Batch cold-rolled ribbed steel bars randomly selected three 5.5mm cold-rolled steel prices, with two cold-rolled steel tensile test, a cold bending test. Through experiments, cold-rolled ribbed steel bars, batch tests are in line with regulatory requirements.
