AZ150 Galvalume Steel Coil

AZ150 galvalume steel coil has a coating thickness of 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. It also helps protect steel from trimmed edges and scratches.

AZ150 is a hot-dip aluminum-zinc alloy coated steel. The resulting coating has excellent corrosion resistance and can be used in harsh environments. This combination produces a durable and corrosion-resistant material that can be used in any application with high strength or hardness.

Once the coil 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. AZ150 aluminized zinc is a high-quality, corrosion-resistant alloy commonly used in the construction and transportation industries. It has strong anti-rust, anti-oxidation and anti-corrosion capabilities, and is an option for those who need to transport items or expose items to severe weather conditions.

Mechanical Properties

The production process of galvalume coated steels coil usually involves several stages, including:

1. Cleaning and preparation: The process begins with cleaning the raw steel coil to remove any dirt, oil or rust. The coils are then dried and pre-treated with chemicals to improve their adhesion to the coating.

2. Coating: The pretreated coils are coated with a mixture of aluminum (55%), zinc (43.5%) and silicon (1.5%) in a continuous hot-dip process. The mixture forms a galvanized coating on steels surfaces with excellent corrosion resistance.

3. Cooling: After the coating process, the coil is cooled in a controlled environment to cure the coating and improve its adhesion to the steel surface.

4. Finishing: Then the galvalume coil is trimmed, leveled and cut to size. They are also quality checked to ensure they meet the required specifications for thickness, width and surface finish.

5. Packaging and Shipping: The finished galvalume coils is then packaged and shipped to customers for various applications such as roofing, siding, and automotive manufacturing.

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.
