3003 Color Coated Aluminium Coil for Corrugated Roofing

Product Overview

3003 Color Coated Aluminium Coil is a premium architectural-grade prepainted aluminum product manufactured from AA3003 aluminum alloy, one of the most widely used manganese alloy aluminum materials for roofing and building applications. Combining excellent corrosion resistance, superior formability, lightweight performance, and high-quality PE, HDP or PVDF coating systems, this product is specifically designed for corrugated roofing sheets, trapezoidal roofing panels, standing seam roofing systems, wall cladding, rainwater systems, and prefabricated steel buildings.

Compared with galvanized steel roofing materials, 3003 color coated aluminum coil offers outstanding corrosion resistance, significantly lighter weight, excellent roll-forming performance, and a much longer service life. The addition of manganese improves the alloy's mechanical strength while maintaining excellent ductility, making it the preferred material for continuous roll-forming production.

As a professional Color Coated Aluminium Coil Manufacturer in China, we provide customized alloy tempers, coating systems, colors, embossing, protective films, and OEM & ODM manufacturing services for roofing sheet manufacturers, distributors, building material suppliers, and construction companies worldwide.
