🛠️ Product Description
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.
Excellent weather resistance allows for over 20 years of service without maintenance. Early test results indicate that it has survived decades of intense sun exposure, erosion from industrial waste, and temperature variations without requiring maintenance. Aluminium-zinc plate is the choice of architects and homeowners globally for its excellent resistance to erosion.
