Cold rolled steel is a low-carbon steel that is finished at room temperature. Due to its processing, cold rolled steel sheets are typically more durable than hot rolled steel, and have a better-looking finish which makes it a prime metal for applications such as automotive and appliances, where finish matters in both form and function.
Mead Metals stocks ASTM A109 cold rolled strip steel in tempers 1 lb (full hard) through 5 lbs (dead soft). ASTM A109 strip steel offers tighter thickness tolerances than ASTM A1008 steel. It is highly formable, depending on temper, and is useful in a wide range of applications.
