The process can also be used to reduce the steel sheet to a very small thickness. Cold rolling may be done using a single pass through a multiplestand mill, or via several passes through a singlestand mill. Beyond a certain level of hardness, the metal may crack if it is rolled again, requiring annealing before further rolling.

The purpose of the continuous galvanizing line (CGL) is to apply a coating of zinc or zinc/aluminium onto the surface of steel strip to improve corrosion resistance. Galvannealing is optionally performed to alloy the coating into the steel substrate. This requires accurate temperature monitoring at the exit of the galvanneal section.
