Cold rolled steel is a sheet metal product formed by passing a steel strip through a series of "stands". Each stand is a set of rolls which exert force on the top and bottom of the strip which reduces the thickness of the steel. The final step in cold-rolling is annealing. In a continuous cold mill, the annealing is handled in-line.

Cold Rolling. In the cold rolling process, a hot-rolled coil is made thinner by passing it between two rolls at room temperature. Not only is the thickness of the material made uniform, but the internal structure is made homogeneous at a microscopic level, and the surface of the roll is transferred to the material to provide a polished finish.
