Cold Roll Coil & Sheets

Cold rolling technology refers to a process whereby steel or stainless steel metals are rolled at room temperature rather than being heated to 1100 degrees Celsius. Rolling steel at room temperature by passing it through rollers enables shaping. Furthermore, this thermal treatment can be used to produce flat sheets of metal, coiled products or sections. The raw material is thereby passed through rollers below its recrystallization temperature of the relevant type of steel or stainless steel.

The crystalline structure is also deformed. Additionally, the grain size is reduced resulting in increased strengthening. The steel must be passed through the rollers several times to obtain the level of thickness or the shape required, this can take longer than the hot rolling process.
