55% Al-Zn Coated Steel Coil

Description:
Galvalume metal coil is an essential alloy cloth frequently used in each day life. Galvalume metal 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 complete shape is composed of aluminum-iron-silicon-zinc, forming a dense quaternary structure.

Passivation
The passivation treatment of the galvanized layer can avert the incidence of folding rust (white rust) beneath humid temperature storage and transportation conditions. But the anti-corrosion ordinary universal overall performance of this chemical therapy is limited, and it hinders the adhesion of most coatings. This remedy is normally no longer used on zinc iron alloy coatings. Except for easy surfaces, as a routine, the manufacturing plant passivates one-of-a-kind kinds of galvanized coatings.

Oiling
Applying oil can limit the corrosion of metal plates under humid storage and transportation conditions. After passivation treatment, the metal plates and strips can be in addition diminished with the useful resource of making use of oil under humid storage conditions. The oil layer have to be succesful to be eradicated with a degreaser that does now now no longer injury the zinc layer.

Lacquer sealing
By making use of an pretty skinny layer of obvious natural coating film, an larger anti-corrosion effect, specifically fingerprint resistance, can be provided. It can adorn lubrication all via molding and serve as an adhesive layer for subsequent coatings.
