Cold rolled steel is hot-rolled steel that has been cleaned of iron oxide scale (pickled) and reduced to a specific thickness through a series of rolling stands (tandem mill) or passed back and forth through a reversing rolling mill. The steel can be heated to controlled temperatures (annealing) depending on mechanical property requirements, and final rolled to the desired thickness.
This produces steel with precision dimensional tolerances and a wide range of controlled surface finishes. Use Cold-rolled steel where thickness tolerance, surface condition, and uniform mechanical properties are of the utmost importance.
