Aluminium Zinc Coils Roofing Sheet Az150 ASTM A792m Building Material Anti-Finger Gl Dx51d+Az Zincalume Alu-Zinc Coated Az150 Galvalume Steel Sheets

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

Performance and major applications:
Excellent weather resistance allows for over 20 years of service without maintenance. Early test results of the roof and wall system indicate that it has survived in decades of intense sun exposure, erosion from industrial waste, and temperature and pressure without requiring any maintenance. Aluminium-zinc plate is the choice of architects and homeowners of all ages, and its excellent resistance to erosion is the reason why this type of roof and wall surfaces are widely used. Studies have shown that such roofing systems can be expected to last 30 years or more in most cases.
