    Passivation

    Passivation treatment of the galvanized layer can reduce folding rust (white rust) under moisture storage and transportation conditions. However, the anti-corrosion performance of this chemical treatment is limited, and it hinders the adhesion of most coatings. This kind of treatment is generally not used on the zinc-iron alloy coating. In addition to the smooth surface, as a rule, the manufacturer will passivate other types of zinc coatings.

    Oiling

    Oiling can reduce the corrosion of steel plates under humid storage and transportation conditions. After passivation treatment of steel plates and steel strips, repainting oil will further reduce the corrosion under humid storage conditions. The oil layer should be able to be removed with a degreaser that does not damage the zinc layer.

    Paint seal

    By coating a very thin transparent organic coating film, it can provide an additional anti-corrosion effect, especially fingerprint resistance. It can improve lubricity during molding and act as an adhesion base layer for subsequent coatings.

    Phosphating

    Through phosphating treatment, galvanized steel sheets of various coating types can be coated without further treatment except for normal cleaning. This treatment can improve the adhesion and corrosion resistance of the coating, and reduce the risk of corrosion during storage and transportation. After phosphating, it can be used with a suitable lubricant to improve the molding performance.

    No processing

    Only when the orderer has requested and is responsible for the non-treatment, the steel plates and steel strips supplied in accordance with this standard can be without passivation, oiling, paint sealing or phosphating and other surface treatments.

    ♦ Application

    Galvanized coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry and fishery and commerce industries. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grilles, etc.; the light industry uses it to manufacture household appliance shells, civil chimneys, kitchen utensils, etc., and the automobile industry is mainly used to manufacture corrosion-resistant parts for cars, etc. ; Agriculture, animal husbandry and fishery are mainly used as food storage and transportation, meat and aquatic products refrigeration processing tools, etc.; commercial mainly used as material storage and transportation, packaging tools, etc.
