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 straight 7.5mm cold-rolled steel prices, Q235 base metal in the cross-sectional reduction rate of 20-30%, the strength and elongation index requirements can LL550 cold-rolled ribbed steel bars. In addition to cold-rolled ribbed steel wire rod rolling ФR7 Ф8 appropriate, the remaining section meet the specifications of the compression rate is too large wholesale 7.5mm cold-rolled steel straight, resulting in high product strength, and elongation of less than 8%. Construction Points rolled ribbed steel bar: cold-rolled ribbed steel processing. After straightening machine Straightening 7.5mm cold-rolled steel rebar straight purchase, no obvious scratches the surface; after bar straightening should not have local bending, bending of straight bars per meter and the total length should not exceed four thousandths. Tolerance of cold-rolled ribbed steel processing: the length of the reinforced ± 10mm, inner hoop net size is ± 5mm. 7.5mm cold-rolled straight rebar suppliers _ _ Jiangsu Dingding cold rolled steel cold-rolled straight by Ding Ding Industrial Co., Ltd., Henan Province.
