Characteristic
Excellent corrosion resistance: the coating consists of 55% aluminum, 43.4% zinc and 1.6% silicon, and the dense oxidized film on the surface can resist the erosion of the atmosphere, rain, humidity, mild acid and alkali. Its rust resistance is 2-6 times higher than ordinary galvanized sheet.
Self-healing of cuts: Aluminum-zinc alloy at the cutting edge will flow to cover the bare metal, reducing the risk of local corrosion.
High-temperature stability: the melting point of aluminum (660 ℃) is much higher than zinc (419.5 ℃), so that the aluminum-zinc coated sheet can withstand temperatures of about 250 ℃, short-term up to 300 ℃ or less, high-temperature environment to maintain structural stability.
Formability: DX51D grade cold rolled steel base, both certain strength and toughness. Can be stamping, bending, stretching and other cold processing, adapted to the manufacture of complex structures.
Weldability: The silicon element in the plating improves the weldability, and by adjusting the process parameters, it can be realized to weld with ordinary steel plate.
Painting performance: the surface oxide film has strong adhesion to the paint, and it is not easy to appear peeling and shedding after painting, and it is easy to adjust the appearance color according to the demand.

Beautiful surface: the surface is silver gray metallic luster, flat and smooth, no need for additional treatment to maintain a good appearance; can be painted, laminating, printing and other secondary processing, and the coating is not easy to fall off.
Economy: Although the initial cost is higher than ordinary galvanized sheet, compared with stainless steel or pure aluminum sheet, aluminized zinc steel maintains high performance while costing less, and is easy to maintain and does not need to be replaced frequently, resulting in a higher overall cost-effectiveness.
Application Areas
Construction field
Roof and wall: can be used for the construction of roofs and walls of industrial plants, warehouses, commercial buildings, and residential buildings.
Steel structure protection: anti-corrosion coatings for bridges and elevated steel structures to reduce maintenance costs and extend life.
Partitions and decoration: used for indoor partitions, ceilings or exterior wall decoration, sound insulation walls, etc.
Home appliance manufacturing
Shell and components: used to make refrigerator, washing machine, air conditioner shell, back panel, or internal structural parts, also used for LCD frame, CRT explosion-proof belt, LED backlight, and other components. Thanks to its good formability.
Kitchen appliances: used for external protection of high-temperature resistant home appliances such as ovens and microwave ovens, using the heat resistance of aluminum elements in the coating.
