Hot rolled steel as raw material has been processed through pickling to remove the oxide scale then cold rolling. The production of cold rolled steel strips include the picking, cold rolling, degeasing, annealing, leveling, finishing, polishing, etc, It not only achieves to the highest production efficiency and the most perfect automation control in the steel field by the production department, but also representing the outstanding and greatest level of steel rolling technology. Our cold-rolled steel coils must be under further processes after annealing, including cutting head & tail, trimming, straightening, leveling, recoiling or slitting.etc
