Cold rolled steel is hot-rolled steel that has been cleaned of iron oxide scale (pickled) and reduced to a specific thickness through a series of rolling stands (tandem mill) or passed back and forth through a reversing rolling mill. The steel can be heated to controlled temperatures (annealing) depending on mechanical property requirements, and final rolled to the desired thickness.

Rolling equipment is roughly divided into three kinds; namely, hot rolling mills, cold rolling mills, and foil mills. Usually, rolling is performed by applying a load to the materials by forcing them vertically through a pair of work rolls. The work rolls are deformed by the high load during the rolling process.

Cold-rolled sheet steel is produced from hot-rolled sheet with additional processing steps such as pickling, cold reduction, annealing and temper rolling. Cold-rolled steel is a product that has been cold reduced, as opposed to hot-rolled, in order to impart specific mechanical properties, surface finish, gauge tolerance and strip shape.
