AZ150 Galvalume Steel Coil Aluzinc Steel Coil

Description:
Galvalume steel coil is an critical alloy material regularly used in every day life. Galvalume metallic coil is composed of aluminum-zinc alloy structure, which is composed of 55% aluminum, 43% zinc and 2% silicon solidified at a excessive temperature of 600°C. Its entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary structure.

Passivation
The passivation cure of the galvanized layer can prevent the incidence of folding rust (white rust) under humid temperature storage and transportation conditions. But the anti-corrosion normal commonplace standard overall performance of this chemical therapy is limited, and it hinders the adhesion of most coatings. This treatment is usually no longer used on zinc iron alloy coatings. Except for effortless surfaces, as a routine, the manufacturing plant passivates one-of-a-kind sorts of galvanized coatings.

Oiling
Applying oil can restriction the corrosion of metallic plates beneath humid storage and transportation conditions. After passivation treatment, the metallic plates and strips can be in addition diminished with the beneficial aid of making use of oil beneath humid storage conditions. The oil layer have to be succesful to be eradicated with a degreaser that does now now no longer damage the zinc layer.

Lacquer sealing
By making use of an incredibly skinny layer of apparent herbal coating film, an large anti-corrosion effect, in particular fingerprint resistance, can be provided. It can embellish lubrication all with the aid of molding and serve as an adhesive layer for subsequent coatings.
