The cold rolled steel plates, following the cold rolling process, undergoes annealing and temper rolling to obtain consistency in thickness, flatness, and smooth surface. In addition, these treatments provide cold-rolled sheets and coils with superior mechanical properties. As a result, cold-rolled sheets and coils are highly workable and are suitable for metallic coating, painting, or other such treatments.
