    Aluminium Zinc Galvalume Steel Coil


    Galvalume Steel Coil(55% Aluminium-Zinc Alloy Coated Steel Coil)

    Hot-dip aluminium-zinc-plated steel sheet is based on cold-rolled steel sheets of various strengths and thickness specifications, and aluminium-zinc alloy has excellent corrosion resistance.

    Galvalume is developed on the basis of hot-dip aluminium plating and hot-dip galvanising technology, which has both the excellent atmospheric corrosion resistance and heat and oxidation resistance of aluminium plating products and the excellent electrochemical protection of galvanised steel sheet products, so that the cuts and scratches are not easy to corrode and rust.

    Corrosion resistance: The corrosion resistance of "aluminized zinc steel coil" is mainly due to aluminum, aluminum's protective function. When the zinc wears down, the aluminum forms a dense layer of aluminum oxide, preventing the resistance from further corroding the interior.
    Heat resistance: Aluminum zinc alloy steel coil has good heat resistance, can withstand the high temperature of 300 degrees Celsius, and aluminum plated steel plate high temperature oxidation resistance is very similar, often used in chimney tubes, ovens, illuminators and daylight lampshades.
    Thermal reflectivity: Aluminized zinc steel coil has a high thermal reflectivity, twice that of galvanized steel, and is often used as insulation material.
    Economy: Because the density of 55%AL-Zn is less than that of Zn, the area of the aluminum-zinc coil is more than 3% larger than that of the steel coil, given the same weight and the same thickness of the gold coating.

    Main advantages:
    1) The coating can be applied to both sides of the metal, giving a high quality finish to the pre-treated metal, with uniformity of colour, thickness, texture and performance.

    2) PPGI not only makes the manufacturing plant more environmentally friendly, it also solves the problem of oil and residual oil.

    3) Manufacturing versatility: any company involved in the production of metal roofing, appliances, wall panels, beverage cans, automotive parts, office equipment and other utility products uses prepainted metal in the manufacturing process.


    The coating consists of 55% aluminum, 43.5% zinc, and 1.5% silicon in weight ratio, respectively. The production process of aluminum zinc steel sheet is similar to that of galvanized steel plate and aluminum plated plate, and it is a continuous melting coating process. 55% aluminum zinc alloy coated aluminum zinc steel plate has superior corrosion resistance compared to galvanized steel plate of the same thickness when exposed to the same environment on both sides. 55% aluminum zinc alloy coated aluminum zinc steel ( 55% Alu-zinc Steel) plate not only has good corrosion resistance, but also color coated products have excellent adhesion and flexibility.
