The skin-pass or temper rolling of galvanized steel is a cold deforming process that takes place after the galvanizing and before painting processes. Deforming during the skin pass is low (0.5-4%). The "skin-pass" process aims are: a) to improve the surface appearance by eliminating the flower feature of hot-dip zinc coatings, b) to reduce the yield stress and
