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…
