ASTM Z275 Galvanized Steel Coil Sheet Blasting Hot Dip 2000mm
The passivation treatment of galvanized layer can reduce the folding rust (white rust) under the condition of tide temperature storage and transportation. But the corrosion resistance of this chemical treatment is limited and, moreover, hinders the adhesion of most coatings. This treatment is generally not used in zinc-iron alloy coating, in addition to the finish surface, as a routine, the manufacturer of other types of galvanized layer are passivation treatment.The oil layer should be able to be removed with a degreaser that does not damage the zinc layer.
