3105 Painted Aluminium Coil for Standing Seam Roofing

Product Overview

3105 Painted Aluminium Coil is a premium architectural-grade prepainted aluminum product manufactured from AA3105 aluminum alloy, containing manganese and magnesium for enhanced strength, excellent corrosion resistance, and superior formability. Compared with AA3003 alloy, AA3105 provides improved mechanical properties, making it one of the preferred aluminum materials for standing seam roofing, concealed fixing roof systems, architectural wall cladding, rainwater goods, fascia panels, soffit systems, and modern commercial buildings.

Available with PE, SMP, HDP, and PVDF coating systems, 3105 painted aluminium coil offers exceptional color retention, UV resistance, weather durability, and long-term exterior performance. Its excellent flexibility allows continuous roll forming without paint cracking, making it ideal for high-speed roofing panel production.

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