Cold Rolled Steel is a rolling process at temperatures that are close to normal room temperature are used to create cold rolled steel. This increases the strength of the finished product through the use of strain hardening by as much as 20 percent. High quality steel that has been processed in this manner has a gray finish that feels smooth to the touch. The cold rolled process creates a finished product that is more precise dimensionally than a hot rolled product. This is because it is already closer to the finished dimension since it has already gone through the cooling process.
