Galvalume Steel nominally contains 55% aluminium, 43.5% zinc and 1.5% silicon alloys by weight. Applied by the traditional hot-dipping process, the product is ideal for applications that require superior corrosion resistance and heat reflectivity. The product’s shiny spangled appearance is attractive enough to be used without painting. It has better resistance towards oxidation and can withstand temperatures up to 315°C without dis-colouration. .
