Cold-rolled steel is produced in cold reduction mills where the material is cooled at near room temperature, followed by annealing and/or tempers rolling. This process produces steel that has a wide range of surface finishes and is superior in tolerance, concentricity, and straightness compared to hot-rolled steel.
