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. 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.

1.The corrosion of the cutting surface of 55% Al-Zn alloy coated Al-Zn steel sheet is the biggest concern of the users since the commercialization of Al-Zn steel sheet. However, after more than 15 months of experience in various environments, it has been proven that the corrosion resistance of zinc-aluminum coated steel sheets is excellent even at the section level, thus completely eliminating the user's concerns.
2.The long-term corrosion resistance of metal plating products mainly depends on the melting rate of the plated material and the thickness of the plating, the melting rate of the galvanized layer of galvanized steel sheet is higher than that of the 55% Al-Zn alloy plated Al-Zn steel sheet. Therefore, the service life of the 55% Al-Zn alloy coated Al-Zn steel sheet is longer than that of the galvanized steel sheet. Based on the weight loss of Al-Zn coated steel sheets exposed to the atmosphere for a long period of time, Bethlehem Steel has concluded that Al-Zn coated steel sheets with 55% Al-Zn alloy are 2 to 4 times more corrosion-resistant than G-90 galvanized steel sheets, which is widely accepted in the industry.

corrosion resistance
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.
heat resistance
Galvalume steel coil has relatively good heat resistance and will not change color when exposed to temperatures of around 316 degrees for a long time. It still has good antioxidant properties at a temperature of 677 degrees.
BOMIS is a Chinese galvalume steel coil manufacturer. We have the ability to supply AZ165 galvalume to meet customers' requirements for use in highly corrosive areas. We ensure that the weight of the metallic coating does not cut corners, and we have the equipment to detect it.
We mainly sell AZ50, AZ55galvalume steel coils. AZ50 and AZ55 are ASTM A792 standard coating designations, meaning weights of 0.50 ounces/square foot and 0.55 ounces/square foot. AZ150 is a coating designation according to EN 10346 standard, which means the weight is 150g per square meter.
AZ50 is equivalent to AZ150;
AZ55 is equivalent to AZ165;
In addition we can also produce galvalume with lower coating weight, please contact sales.
