AZ55 Galvalume Steel Sheet Description
AZ55 is the standard for galvanized steel sheets and coils used in a variety of applications, including roofing and siding. The AZ55 name refers to the thickness of the coating on the steel plate or coil, which is between 0.375 and 1.5mm (0.015 and 0.059 inches).
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.
Scope of Application
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.
