Aluminum and zinc plating steel coils


Product Category:

The corrosion resistance of 55% aluminized zinc coated steel coils is 2 to 6 times that of galvanized steel sheets. Due to its superior corrosion resistance and processing performance, they can be directly used as building roof panels, civil and home appliance backplates, and are also widely used as color coated substrates. The smooth production of aluminum zinc plated plates not only enriches the company's product range, but also provides more flexible options for future market layout and strategic planning.

    Heroes of aluminized zinc coated steel coils:

    55% aluminized zinc coated steel coils have barrier layer protection functions from aluminum and sacrificial protection functions from zinc. When zinc is cut or scratched, aluminum will form an insoluble oxide layer to play a protective role. In addition, the density of aluminum and zinc plating is low, and the coating thickness of the same weight is much thicker than that of zinc plating. In addition to corrosion resistance and high temperature resistance, 55% aluminum zinc plated plate has good reflectivity and good adhesion of the paint coating. There are also 55% aluminum plated zinc plates in various zinc flake states, with a beautiful surface and suitable for external use.

    1. Overview of aluminum and zinc plating steel coils

    There are unique smooth, flat and magnificent stars on the surface of aluminized zinc. The primary color is silver. The plating consists of 55% aluminum, 43.4% zinc and 1.6% silicon. The production process of aluminized zinc is similar to that of galvanized steel plates and aluminized steel plates, i.e., the continuous melting plating process.

    When both sides of the aluminized zinc cladding of 55% aluminum-zinc alloy and the same thickness of galvanized steel sheets are exposed to the same environment, the corrosion resistance performance of the former is better. Except for the excellent corrosion resistance performance, coated products are characterized by excellent adhesion and flexibility.

    4. Advantages of aluminum zinc plated steel coils

    (1) Thermal Reflectivity. Aluminum zinc plated steel plate has a high thermal reflectivity, which is twice as high as galvanized steel plate. It is often used as a thermal insulation material.

    (2) Heat resistance. Aluminum zinc alloy steel plate has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It has similar high temperature oxidation resistance to aluminum plated steel plate, and is often used in chimney tubes, ovens, lighting fixtures, and fluorescent lampshades. (3) Corrosion resistance. The corrosion resistance of aluminum coated zinc steel coils is mainly due to the protective function of aluminum. When zinc is abraded, aluminum forms a dense layer of aluminum oxide, preventing corrosion resistant substances from further corroding the interior. (4) Economy. Because the density of 55% AL-Zn is smaller than that of Zn, the area of aluminum zinc plated steel plate is more than 3% larger than that of galvanized steel plate with the same weight and the same thickness of the gold plating layer. (5) Easy to paint. The aluminum zinc plated plate has excellent adhesion to the paint and can be painted without pre-treatment and weathering treatment. Because the density of 55% AL-Zn is smaller than that of Zn, the area of aluminum zinc plated steel plate is more than 3% larger than that of galvanized steel plate with the same weight and the same thickness of the gold plating layer. (6) Aluminized zinc plated steel plate has a gorgeous silver white surface. (7) Aluminum zinc plated steel plate and galvanized steel plate have similar processing and spraying properties.

    Characteristics of aluminum zinc plated steel coils

    1. Thermal reflectance of aluminized zinc coated steel coils:

    "The thermal reflectivity of aluminum zinc coated steel coils is very high, twice that of galvanized steel plates. People often use them as heat insulation materials.".

    2. Heat resistance of aluminum zinc plated steel coil:

    Aluminum zinc alloy steel plate has good heat resistance and can withstand high temperatures of over 300 degrees Celsius, which is similar to the high-temperature oxidation resistance of aluminum zinc coated steel coils. Aluminum zinc coated steel coils are often used for chimney tubes, ovens, lighting fixtures, and fluorescent lampshades. Corrosion resistance:

    The corrosion resistance of aluminum coated zinc steel coils is mainly due to the protective function of aluminum. When zinc is abraded, aluminum forms a dense layer of aluminum oxide, preventing corrosion resistant substances from further corroding the interior.

    3. Economy of aluminized zinc coated steel coils:

    Because the density of 55% AL-Zn is smaller than that of Zn, the area of aluminum zinc plated steel plate is more than 3% larger than that of galvanized steel plate with the same weight and the same thickness of the gold plating layer.
