Cold rolled coils
Cold rolled coilshave received an additional treatment after it has beenhot rolled, pickled and oiled. The coils are moved into a series of rollers to lower its thicknesses and to have uniform surface smoothness. The process is done at room temperature. Cold rolled coils can then be further annealed to soften the steel. These characteristics, depending on the end-use, change with the intensity of the annealing.
