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.
2 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.
3 Lacquer 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 serve as an adhesion base layer for subsequent coatings.
4 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.
5 No processing
Only when the orderer requests for non-treatment and is responsible for it, the steel plates and strips supplied in accordance with this standard can be without passivation or oiling or paint sealing or phosphating and other surface treatments.We could also provide the product life length lasts for decades as customers required.
Suitable for many industry
Construction industry: outdoor applications: roofs, roof structures, roller shutter doors, kiosks, shutters, guard doors, street waiting rooms, ventilation ducts, etc.
Electrical appliances: refrigerators, air conditioners, electronic stoves, washing machine shells, oil stoves, etc.
Transportation industry: car ceilings, back panels, hoardings, car shells, tractors, ship bulkheads, etc.
Widely used in steel structure workshops, composite board workshops, and color steel tile factories are most used.
