Alloy Color Coated Aluminum Sheet - Mill Direct Supplier
Alloy color coated aluminum sheet is a premium-grade surface-treated metal product that finds extensive application across construction, transportation, home appliances, and industrial manufacturing sectors. Produced by applying high-performance organic coatings — such as PVDF, polyester (PE), or epoxy — onto alloy aluminum substrates, these sheets deliver a compelling combination of aesthetic appeal, structural integrity, and long-term durability. The coating process not only enhances visual versatility with a broad spectrum of RAL and custom colors, but also significantly improves resistance to UV radiation, moisture, and chemical exposure. As a mill-direct supplier, we offer consistent product quality backed by rigorous quality control at every production stage, ensuring that each sheet meets international standards such as ASTM B209, EN 485, and GB/T 17748. Whether you require standard stock dimensions or custom-cut panels for large-scale projects, our alloy color coated aluminum sheet solutions are engineered to meet the most demanding specifications at cost-effective mill-direct rates.

What is Alloy Color Coated Aluminum Sheet?
Alloy color coated aluminum sheet refers to an aluminum alloy substrate — commonly 1100, 3003, 3105, 5052, or 6061 series — that has been pre-treated, primed, and finished with one or more layers of organic coating. The result is a lightweight yet structurally robust panel that combines the natural corrosion resistance of aluminum with enhanced surface protection and decorative functionality, making it suitable for both interior and exterior environments.

Alloy Color Coated Aluminum Sheet Manufacturing Process
Manufacturing begins with selecting a qualified alloy substrate, followed by degreasing and chromate or chromate-free chemical pre-treatment to ensure optimal coating adhesion. A primer coat is applied first, then one or two finish coats of PVDF or polyester resin are cured in a continuous coil-coating furnace at temperatures between 200°C and 250°C. Final inspection includes adhesion cross-cut testing, pencil hardness evaluation (≥2H), and T-bend flexibility assessment to confirm coating integrity before coiling and packaging.

Alloy Color Coated Aluminum Sheet Technical Specifications
Available alloy grades include 1100-H14, 3003-H16, 3105-H24, and 5052-H32, with thickness ranging from 0.20 mm to 4.00 mm and width up to 1,600 mm. Tensile strength varies by alloy — for instance, 5052-H32 achieves a minimum of 228 MPa per ASTM B209. Coating thickness for PVDF finish is typically 25–30 µm (top coat) with a 5–7 µm primer, offering a salt spray resistance exceeding 1,000 hours per ASTM B117. Gloss level is customizable from 10 to 85 GU (60° geometry), and more than 200 standard RAL colors are available alongside custom color matching services.
