|---|---|---|
| Product Name | Aluminum Color Coating Processing | Pre-painted / color-coated aluminum coil and sheet with decorative or functional surface treatment |
| Material Grade | 1100, 3003, 3105, 5052, 8011 (AA / EN AW equivalent) | AA 1100 ≈ EN AW-1100; AA 3003 ≈ EN AW-3003; AA 5052 ≈ EN AW-5052 |
| Standard Compliance | ASTM B209, EN 485-2, GB/T 3880, AAMA 2603/2604/2605 | Covers mechanical properties, coating performance, and dimensional tolerances for color-coated aluminum |
| Chemical Composition | Al ≥ 99.0% (1100); Mn 1.0–1.5% (3003); Mg 2.2–2.8% (5052); Si ≤ 0.6%, Fe ≤ 0.7% | Composition per ASTM B209 / GB/T 3190; low Cu content ensures corrosion resistance and coating adhesion |
| Tensile Strength | 110–290 MPa (varies by alloy and temper) | 1100-H14: ≥ 110 MPa; 3003-H16: ≥ 150 MPa; 5052-H32: ≥ 228 MPa (per ASTM B209) |
| Yield Strength | 85–215 MPa | 1100-H14: ≥ 85 MPa; 3003-H16: ≥ 130 MPa; 5052-H32: ≥ 193 MPa |
| Elongation | 3–12% | Measured on 50 mm gauge length per ASTM E8; higher elongation grades suitable for deep drawing |
| Coating Type | PVDF, Polyester (PE), SMP, HDP, Epoxy Primer | PVDF (fluorocarbon) meets AAMA 2605; PE meets AAMA 2603; primer coat 5–8 µm, top coat 18–25 µm |
| Coating Thickness | Total DFT: 25–35 µm (PE); 30–40 µm (PVDF) | Dry Film Thickness measured per ASTM D7091; back coat 8–12 µm optional |
| Gloss Level | 10–85 GU (adjustable) | Measured at 60° angle per ASTM D523; matte, semi-gloss, and high-gloss options available |
| Thickness Range | 0.15–4.0 mm | Standard coil thickness; custom gauges available upon request |
| Width Range | 100–2,650 mm | Slit coil or full-width coil; tolerance ±1 mm per EN 485-4 |
| Surface Finish | Smooth, Embossed, Brushed, Wood-grain, Stone-pattern | RAL / Pantone color matching available; salt spray resistance ≥ 1,000 h (ASTM B117) |
| Application | Building facades, roofing, ceilings, signage, automotive trim, household appliances, packaging | Widely used in ACP (Aluminum Composite Panel), roller shutters, rain gutters, and interior decoration |
| Certification | ISO 9001, SGS, CE, RoHS, REACH | AAMA 2604/2605 certification available for architectural-grade PVDF coatings |
| Packaging | Eye-to-sky or eye-to-wall coil on steel pallet; moisture-proof paper + stretch film + wooden case | Inner diameter 505 mm or 610 mm; coil weight 2–5 MT; export seaworthy packaging standard |
| MOQ | 5 MT per color / specification | Mixed colors accepted with minimum 1 MT per color; lead time 15–25 days after order confirmation |
Initial color inconsistency — resolved promptly by supplier
Our first order of 10 MT of polyester-coated 1100-H14 coil, 0.4 mm thick, in RAL 5015, showed a visible gloss variation of approximately 8 GU between the coil edges and center, which fell outside our 5 GU tolerance for appliance panel production. I raised the issue with the technical team within 24 hours of inspection. They acknowledged the deviation, issued a root cause analysis within two days, and arranged a replacement production run at no additional cost, delivered within 12 days. The replacement batch met spec fully. Responsive handling of the issue restored confidence — willing to try again on our next order.
