Cold Rolled Steel Coils 0.3-6mm Thickness 1219mm x 2438mm Size SPCC St12 DC01 Carbon Steel
Zhengde Metal cold rolled steel coils are manufactured using hot-rolled coils as the primary material. These coils undergo bell-type annealing before cold rolling to eliminate work hardening and internal stress, resulting in reduced yield strength comparable to pre-rolled conditions.

Cold rolled steel coils offer superior thickness precision, smooth surfaces, and excellent mechanical properties with enhanced processing capabilities. All coils undergo annealing, pickling, and surface leveling processes to ensure optimal performance.
These coils are widely used in automotive manufacturing, home appliances (refrigerators, washing machines), industrial equipment, and construction materials. Cold rolled hard coils also serve as raw materials for hot dip galvanizing plants.
Manufacturing follows rigorous procedures: hot rolled sheet coils undergo acid washing, cold rolling, degreasing, annealing, leveling, and shearing to ensure consistent quality and performance.
Our advanced slitting equipment processes coils into custom widths for transformers, motors, and specialized industrial applications.
