The alloy-coated product contains 55% aluminum, 43.5% zinc and 1.5% silicon by weight. Applied by the traditional hot-dipping process, Galvalume is perfect for applications that call for high corrosion resistance and heat reflectivity. It is typically used in construction.Galvalume can be used even without a layer of paint over it. It has better resistance to oxidation and can withstand temperatures up to 315°C without discoloration.


  • Increased load carrying capacity higher than Knurled Sections
