    ASTM A792 SS50 Structural Steel AZ120 AFP 55% Aluminum-zinc steel Galvalume Pure used for Frame

    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.

    The surface of the Galvalume / Aluzinc steel sheet presents a unique smooth, flat, and gorgeous spangle looking, with a silver white base color. The special coating structure gives it excellent corrosion resistance. The normal service life of Galvalume / Aluzinc Steel Sheet and Coils can reach 25 years, and they have good heat resistance and can be used in high-temperature environments at 315 ℃; The adhesion between the coating and the paint film is good, and it has good processing performance, which can be used for stamping, shearing, welding, etc; The surface conductivity is very good.


    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.

    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.
