Galvalume Steel

• A flat rolled steel sheet coated with alloy of aluminium and zinc, which has been researched for 20 years
• Galvalume is an aluminum-zinc alloy coated steel; produced by a continous hot dip process that has an attractive appearance.It has the same characteristics with galvanised steel in workability and formability, hence having excellent durability
• The alloy coating comprises about 55% aluminium, 43.4% zinc and 1.6% silicon. This coating combines the superior surface corrosion resistance of aluminium with the cut edge protection of zinc
• It has been well accepted as a prefered alternative to both galvanised steel sheets and aluminum coated steel sheets in such areas as roofing and siding, gutters, automotive components, and home appliances
