What is Galvalume Steel Coil？
Galvalume Steel Coil is also called Al-Zn alloy coated steel coil,Aluminum Zinc steel Coil.Galvalume is an effective method of metal anti-corrosion.Galvalume steel coils are processed by hot-dip plating from cold-rolled steel coils. The coating composition is 55% aluminum, 43.4% zinc and 1.6% silicon. It forms a protective coating that isolates the metal from the surrounding environment. The Aluminum zinc layer can prevent water, humidity and other elements in the air from corroding the steel.
this steel coil is gradually replacing galvanized coil due to its excellent corrosion resistance and is widely used all over the world
