Product Description

AZ stands for aluminum-zinc alloy, which is the material of the steel coating. AZ50 refers to the total weight of both sides of the aluminum-zinc alloy coating in the three-point test in ASTM a972 standard is 0.50 ounces/square foot, which is equivalent to 150 grams/square meter. As the surface coating of AZ50 galvalume steel sheet 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. The mixed structure of hot dip aluminum zinc silicon coating has its unique advantages in corrosion resistance. AZ50 aluminized zinc is a high quality corrosion resistant steel. It is made of a combination of aluminum and zinc, with an aluminum content of at least 50%. AZ50 aluminized zinc is not only suitable for the exterior of your house, but also for structural purposes and industrial applications. This alloy has many advantages, including excellent strength, impact resistance and excellent weldability. Construction industry: such as roof, internal and external wall panels, sound insulation walls, pipes, garages, etc. Automotive industry: such as mufflers, exhaust pipes, wiper accessories, fuel tanks, truck containers, etc. Household appliances: such as refrigerator backplane, air conditioner, microwave oven, LED backlight, electric cabinet, etc Agricultural use: such as greenhouse, granary, pig farm, chicken coop, etc Other industries: such as heat exchangers, dryers, etc.
