The galvalume coating is an alloy consisting of approximately 55% aluminum, 43.4% zinc and 1.5% silicon by weight, which is applied to steel by the continuous hot dip process.
Galvalume steel sheet offers the best qualities of aluminum coated (aluminized) and zinc coated steel sheet (galvanized).
The aluminum/zinc coating has barrier corrosion resistance and heat resistance similar to aluminum coated steel. It also has good bare edge galvanic protection and forming qualities similar to continuously annealed commercial quality galvanized.
The appearance of Galvalume coating is quite distinctive. Its smooth, flat and fine spangle and a silvery metallic appearance make it attractive in unpainted applications.
Galvalume steel coil is high in strength, good in rain and corrosion resistance,suitable to continuous rolling, convenient in installation and disassemble, time saving and low cost, widely used in construction industry, such as modern courtyard design, large-sized industrial buildings, prefabricated thermal insulation sandwich board, etc. Along with the development of light industry, transportation and ship building, the application of galvalume steel coil has been expanded form building materials to automobile manufacturing, watercraft interior decoration. Household electrical appliance, furniture, container and cooker, etc., and become a new material substituting to spray coating steel sheet.
Good performance, high precise, high straightness, high evenness and surface finishing, uniform thickness, easy for coating process, high tensile strength, high pressing property and low yield point.
Steel structure, building exterior application, building material, roofing household, application, tube making, etc…
