Colour Coated Roofing Sheet

July 3, 2023

Colour coated roofing sheet grade 3003 3004 aluminum magnesium manganese alloy is produced by adding manganese and magnesium to ordinary aluminum materials, making the aluminum alloy have better tensile strength, yield strength, and elongation compared to ordinary aluminum sheet. Its tensile and yield strength is doubled compared to ordinary aluminum, and its resistance to oxidation and corrosion is further enhanced. It is known as rust-resistant aluminum in the metal industry, making 3003/3004 aluminum-magnesium alloy widely used due to its rust-resistant and high-strength characteristics.

The surface of the aluminum-magnesium alloy color coated aluminum roofing sheet is treated with degreasing, cleaning, and passivation, and then coated with the most advanced KANAR500 series fluorocarbon (PVDF) resin produced coating at the international level, which has a quality guarantee of more than 20 years of weather resistance. In the production of fluorocarbon coatings, it needs to be baked at a temperature above 270 degrees Celsius to satisfy the consistency of physical properties and color difference between batches.

 

Due to the advantages of the raw materials, the aluminum-magnesium alloy colour coated roofing sheet has high strength, corrosion resistance, and high weather resistance. It has been widely used in roofing and cladding systems of steel structure factories, exhibition halls, stadiums, airports, train stations, etc. After cutting, pressing, punching, and bending, it can be used as a whole roof and wall decoration board for large-span and large-area buildings. The color coated roofing sheet shape can adapt to the diverse and complex facade requirements of modern architecture, such as single-curved, double-curved, fan-shaped, spherical, etc., to achieve the perfect integration of the roof into the entire building, following the design concept of architects.
