    What is aluminium-zinc plated sheet

    Aluminium-zinc plated sheet is a steel plate plating on the basis of zinc with the addition of aluminium (passivation protection), the general composition of 55% aluminium, 43.5% zinc, 1.5% silicon, with excellent resistance to atmospheric corrosion, corrosion resistance of galvanized sheet 2-5 times, but also has the high temperature corrosion resistance of aluminium plate, smooth surface, good appearance, but the formation of its plating and resistance to welding a little worse. In foreign countries generally about 40% of aluminium zinc plating used directly, about 60% of the plate is further as a colour coated substrate.

    Uses: building roofs, walls, electrical cabinets, home appliances, automobiles, colour coated substrates, etc.

    Coating content classification

    • 55% alu-zinc steel plate: the coating consists of 55% aluminium, 43.4% zinc and 1.6% silicon, the corrosion resistance is 2-6 times of galvanised sheet, characterised by high-temperature corrosion resistance, smooth surface, good appearance, but the plating of the molding and weldability is slightly worse.

    • 5% aluminium-zinc steel plate: plated with 5% aluminium, 0.1% mixed rare earth elements, the rest is zinc, corrosion resistance is galvanised sheet 2-3 times, characterized by the plating of the formation is very good, with good coating and welding performance, but the surface is not as bright as high alumina steel plate, fine, so rarely used bare.

    SURFACE TREATMENT

    DESCRIPTION OF USE

    CHROMATE PASSIVATION(C)

    Surface treatment for high-strength steel plates after hot-dip plating to reduce white rust during transport and storage

    Chrome-free passivation(C5)

    Surface treatments that require limiting the amount of hexavalent chromium, etc. in passivation solutions that are harmful to the environment and humans

    Anti-finger print(N)

    Surface treatment after the passivation process, which acts as a lubricant during processing, prevents fingerprints from staining during operation, and prevents premature blackening of the surface during use.

    Chrome-free and fingerprint resistant(N5)

    Surface treatment after the passivation process, in the process of lubrication, to prevent the operation of the fingerprint staining, to prevent the use of the surface of the process of premature blackening, and at the same time, the requirement to limit the fingerprint-resistant film harmful to the environment and human body, such as hexavalent chromium content

    Oiled(O)

    Surface treatment added after the passivation process to further reduce rusting during long-distance transport and long-term storage
