• Coldrolled nonferrous sheet may be produced from hotrolled strip, or in the case of certain copper alloys it is coldrolled directly from the cast state. Cold rolled strips Cold rolled metals are rated as 'temper' • Skin rolled : Metal undergoes the least rolling ~ % harden, still more workable.

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.

The starting point is usually hot rolled or cold rolled steel, annealed, pickled and skin passed. Then, finer grit belts and brushes give the steel a satin polish. The 1K – 2K finish provides a smooth reflective surface with an average roughness of micrometers or lower, with some manufacturers getting as low as micrometers.
