Color Coated Aluminum Coil9

Premium-grade aluminum coils with durable PVDF or polyester coatings in 200+ RAL colors, engineered for exceptional weather resistance.

Galvalume Steel: It adopts a 55% aluminum-zinc-silicon alloy coating and forms a dense protective layer through the hot-dip galvanizing process. Its corrosion resistance is 3 to 6 times higher than that of ordinary galvanized steel and can withstand a 1000-hour salt spray test. It features a high-temperature stability of 315℃ and is suitable for highly corrosive and high-temperature scenarios such as industrial plant roofs and photovoltaic brackets.

Galvanized Steel: The hot-dip galvanizing process forms sacrificial anode protection, with a conventional zinc coating thickness of 80-275g/m², meeting the requirements of moderately corrosive environments such as indoor structures and civil buildings. Good weldability and formability make it an economical choice for standardized manufacturing of light steel keels, home appliance shells, etc.

Aluminum Coil/Pipe/Plate: Through alloying with 6061, 7075, etc., and heat treatment, a balance between high strength and lightweight is achieved. The tensile strength of 7075-T6 alloy reaches 572MPa, and its weight is only 1/3 of that of steel. After anodic oxidation treatment, a wear-resistant protective layer is formed, which is widely used in aerospace structural components and lightweight design of new energy vehicles.

Stainless Steel: 316L contains 2% molybdenum and has excellent resistance to chloride ion corrosion. It is suitable for Marine engineering and food processing equipment. 904L super stainless steel is resistant to strong acids and alkalis and is often used in chemical reaction vessels. Medical-grade grades ensure the biocompatibility of implantable devices.

Aluzinc Steel: The same material system as Galvalume, 100% recyclable, the coating has self-healing function and can automatically form a protective film after minor damage. In fields such as prefabricated buildings and logistics turnover boxes, modular application and reuse are achieved.

Prepainted Steel: The PVDF fluorocarbon coating contains over 70% fluorine and has a color retention period of up to 30 years, making it suitable for high-end building curtain walls. The HDP high-weather-resistant polyester coating offers outstanding cost performance and meets the appearance requirements of industrial plants. Supports full-color gamut customization and functional processing such as anti-fingerprint and easy cleaning.

The selection of materials for the project should take into account the environmental corrosion grade, design service life, processing technology and budget cost comprehensively. The six major metal materials complement each other, providing professional and efficient solutions for industries such as construction, manufacturing, and energy.
