It is described that cold rolling changes the mechanical properties of steel by reducing the thickness of steel. 
Cold-rolled steel must be further processed, otherwise it will react with water in the air to form rust. 
In most cases, it is covered with a thin layer of oil to prevent oxygen from reacting to the surface. 
The steel coil is annealed (heated atmosphere) to deform the steel (cold-rolled annealing) or for further processing, galvanized or aluminized. 
Cold rolling is widely used, and each performance has different applications.
