Cold-rolled coils are steel coils made from hot-rolled coils. After pickling to remove the oxide layer at room temperature, they undergo multiple rolling passes (total reduction rate 60-80%), followed by annealing and leveling. The products are characterized by high surface finish, good dimensional accuracy, and excellent mechanical properties.
