High-Grade Protective Coating:

Equipped with top-tier PE polyester and PVDF fluorocarbon coating systems, with professional color fixation and anti-aging treatment, supporting 15-20 years of outdoor service warranty.

Professional Architectural Application:

Custom-developed for modern building facades, curtain wall cladding, metal roofing and architectural trim projects, meeting high-standard commercial and industrial building decoration needs.

Why Choose Our Prepainted Aluminum Coils?

Our 3003/3105 prepainted aluminum coils are engineered exclusively for high-end architectural exterior decoration, solving the core pain points of traditional building materials such as easy fading, poor corrosion resistance and difficult processing. With advanced continuous color coating production technology and high-purity aluminum substrates, our products deliver stable physical properties and superior outdoor weather resistance. Meanwhile, the materials are 100% recyclable, complying with global green building and sustainable development standards, helping construction enterprises obtain green building certifications and reduce project carbon footprints. Whether for coastal high-humidity and salt-spray environments or high-temperature and strong UV radiation areas, our color-coated aluminum coils can maintain stable appearance and structural performance for a long time.

Performance & Advantages

Superior Weather Resistance:

The professional PE/PVDF coating forms a dense protective film on the aluminum surface, effectively resisting UV radiation, high temperature oxidation, rain erosion and salt spray corrosion. It avoids common problems such as surface fading, chalking, peeling and rusting, ensuring long-term outdoor service stability.

Excellent Workability:

The 3003 and 3105 aluminum alloy substrates have excellent bending, rolling and shearing performance. They can be freely processed into various curved panels, flat panels and special-shaped decorative parts without coating cracking, falling off or substrate deformation, supporting personalized architectural design.

Eco-Friendly & Sustainable:

The whole product is made of pure aluminum material, which can be 100% recycled and reused without generating harmful substances. The production process adopts environmentally friendly coating technology with low VOC emission, fully meeting international environmental protection standards and supporting LEED and other green building certification requirements.

Vibrant & Durable Aesthetics:

Adopts precise RAL color matching technology, providing classic RAL green and RAL white mainstream architectural colors. The surface coating is uniform, smooth, flat and free of color difference, scratches and bubbles, maintaining a neat and high-grade architectural appearance for decades.
