55% Hot Dipped Al-Zn/ Galvalume Roofing Sheets

1. Thermal reflectivity: Aluminium-zinc steel plate has a high thermal reflectivity, twice that of galvanized steel plate, and is often used as an insulating material. 2. Heat resistance: Aluminum zinc alloy steel plate has good heat resistance, can withstand the high temperature of more than 300 degrees Celsius, and aluminum plated steel plate high temperature oxidation resistance is very similar, often used in chimney tubes, ovens, illuminators and solar lampshades. Corrosion resistance: The corrosion resistance of aluminium-zinc steel coil is mainly due to aluminum, aluminum protection function. As the zinc wears away, the aluminum forms a dense layer of aluminum oxide that prevents corrosion resistance from further corroding the interior. 3. Economy: Because the density of 55% Al-Zn is lower than that of Zn, the area of aluminized zinc plate is more than 3% larger than that of galvanized steel plate under the condition of the same weight and the same thickness of gold plating. 4. Easy to paint on The aluminized zinc plate has excellent adhesion to the paint and can be painted without pretreatment and weathering. The coating adhesion of the gold layer of aluminum zinc plate is excellent, so it can be directly coated on advertising board or general use board without pretreatment. 5. Aluminium-zinc plated steel plate has an ornate silver-white surface. 6. Aluminized zinc steel plate and galvanized steel plate have similar processing performance and spraying performance.
