24 Gauge G90 Hot DIP Galvanized Steel Coil Aluzinc Steel Plate Az275 Anti Finger Print Roof

24 Gauge G90 Hot DIP Galvanized Steel Coil Aluzinc Steel Plate/Sheet Galvalume Steel Coils Az275 Anti Finger Print Roof

Galvalume steel coil has good corrosion resistance. It can balance the protective and repair effects of zinc with the anti-corrosion effect of aluminum, extending the service life of steel sheets.

The substrate composition of aluminium-zinc silicon steel plate is composed of 55%aluminum,43.5%zinc
and 1.5%siicon which combines the physical protection and high durablity of aluminum with theelectrochemical protection properties of zinc.Under the same conditions,its corrosion resistance is 4-6 timesof galvanized sheet.It's an ideal material used for the roof and outer walls.

Galvalume Steel Coil Aluminum-zinc plated steel sheets have a characteristic smooth, flat and ornate starburst surface with a silvery-white base color. The coating composition consists of 55% aluminum, 43.4% zinc and 1.6% silicon by weight. AFP galvalume coil is a composite coated coil obtained by performing fingerprint-resistant treatment on the surface of galvalume sheet., The production process of Al-Zinc plated steel sheet is similar to that of galvanized and aluminized steel sheet, which is a continuous melt coating process. 55% Al-Zinc alloy coated Al-Zinc plated steel sheet has superior corrosion resistance compared to galvanized steel sheet of the same thickness when exposed to the same environment on both sides. 55% Al-Zinc alloy coated Al-Zinc plated steel sheet not only has good corrosion resistance, but also has excellent adhesion and flexibility.
