Pre Painted Aluminum Sheet Metal

The coating selection of pre painted aluminum sheet metal can be considered according to the application field and project cost requirements. According to the weather resistance and anti-corrosion performance of the coating, the coatings of pre painted aluminum sheet are followed by PVDF fluorocarbon (polyvinylidene fluoride), HDP high weather resistance polyester, PE polyester and other coatings.

6 advantages of pre painted aluminum sheet metal

1, Good durability, pre painted aluminum sheets comes with anti-corrosion function

Aluminum molecules combine with oxygen in the air to form an aluminum oxide film that covers the surface of the aluminum plate to prevent further oxidation of the aluminum plate and form a natural protective film with its own anti-corrosion function.

2, Light weight, reduce the load of supporting structure

The density of alloy aluminum is 2.73, which is one-third of that of steel plate. It is light in weight and greatly reduces the load of supporting structures. So pre painted aluminum sheet roofing system is widely used in long-span construction fields such as airports, stations, and stadiums.

3, High strength, strong rigidity

Due to the addition of metal components such as magnesium and manganese to the 3003 pre painted aluminium sheet metal, the strength and rigidity of the painted aluminum coil are greatly enhanced through the composition configuration, and its load-bearing performance is improved.

4, Good plasticity and easy processing

It can be bent into straight boards, inner arcs, outer arcs, fan-shaped, and can adapt to various shapes of the roof - spherical, arc, fan-shaped, etc., to meet the designer's design concept to the greatest extent.

5, Coating types and colors can be selected on demand

The surface of the pre painted aluminum sheet can be painted with different colors and coating types according to the architectural style and design requirements, which solves the problem of cost and design life, and can fully display the artistic effect of the building.

6, Recyclable, high value

After the ordinary color steel plate is corroded, it can only be sold for a few cents per kilogram. When the prepainted aluminum sheet is recycled, the price can reach between 8.5-9.5% of the aluminum plate, and the recycling value is significantly higher than that of the ordinary color steel plate.

Application range of pre painted aluminum sheet metal:

Due to its good durability, light weight and high lightness, pre painted aluminum sheet is suitable for large venues, airports, high-speed rail stations, theaters and other public buildings and power plants, steel mills, and chemical industry, aquaculture and other industries that have high requirements for anti-corrosion performance.
