than can be rolled by the Hot Mill. Cold Rolling CSI''s cold reduction mill is a series of five rolling mills, or ''stands'' hence the name "5Stand". Each mill stand has two work rolls about two feet in diameter, which are driven by powerful electric motors (totaling over 25,000 horsepower) and sandwich the steel to reduce the thickness.

In cold rolling, the metal piece is not heated immediately prior to rolling but the temperature of the workpiece will rise due to the frictional effects of rolling. Steels that are cold rolled become work hardened and annealing is required in order to obtain the desired hardness. The difference between hot rolled and cold rolled steels is the
