Hot Dip Galvalume Steel Coil
Hot-dip aluminum-zinc plated steel plate is also called aluminum-zinc plated plate, aluminum-zinc plated natural color plate, aluminum-zinc plated fingerprint resistant plate and aluminum-zinc plated light plate. As the surface coating of the plate is an alloy composed of aluminum, zinc and other trace elements, it has outstanding corrosion resistance and gradually replaces galvanized plate. Aluminum-zinc plated plate is mainly used for steel structure roof, wall surface, switch cabinet body and household appliance board.
AZ50 Galvalume Steel Coil
AZ55 Galvalume Steel Coil
AZ55 aluminum zinc plated steel coil is coated with 55% aluminum zinc alloy by hot dip plating process. It has excellent corrosion resistance and can be used in various applications, such as the automotive industry, shipbuilding industry, construction industry, etc. In addition to being an excellent outdoor material, AZ55 aluminized zinc steel coil also has many other advantages. For example, it can be used for electrical equipment manufacturing or decoration, such as fences. In addition to these uses, this steel can also be used in various industrial applications because of its good mechanical properties and corrosion resistance.
AZ150 Galvalume Steel Coil
The thickness of AZ150 coating is 18 microns on one side and 36 microns on both sides. The coating alloy of the steel consists of 55% aluminium, 43.4 zinc and 1.6 silica. This coating of steel acts as a passive barrier to general corrosion. Once the sheet is exposed to electrolyte or moisture, another coating may form a galvanic cell. This exposure results in spillage of zinc ions and corrosion protection of the exposed steel. It also helps protect steel from trimmed edges and scratches.
Galvalume steel coil (also known as aluminum-zinc alloy coated steel coil) is produced from a cold-rolled steel substrate, which is coated by immersion in a molten bath of approximately 55% aluminum, 43.4% zinc, and 1.6% silicon at around 600°C. It uniquely combines the physical barrier protection and high durability of aluminum with the electrochemical (sacrificial) protection of zinc.
