COLD ROLLING STEEL

Cold-rolling steel is the process of steel flattening by passing the steel through a series of rollers. It is called Cold Rolling (or Cold Rolled) because the steel is kept below its recrystallization temperature. Cold rolling steel makes it up to 20% stronger and improves the surface finish. Cold-rolled sheets and strips come in various conditions: full-hard, half-hard, quarter-hard, and skin-rolled.

At Worthington Steel, we have a three-stand tandem cold rolling mill, a reversing mill, and various one-pass mills, which primarily reduce gauge and add value by means of edging and controlling flatness. This is part of our overall cold rolled process, which includes processes such as: flat rolling steel, foil rolling, ring rolling, roll bending, roll forming, and controlled rolling steel.

This cold rolling process and equipment change the mechanical properties of the steel, producing certain useful characteristic combinations*, including (but not limited to):

Ductility
Hardness
Stiffness
Strength
