| Specification Category | Detailed Parameters | Typical Applications | Quality Control Requirements |
| Substrate Thickness | Thin: 0.15mm - 0.3mm | Home appliance panels (refrigerator side panels, washing machine covers), thin signage | Thickness deviation ≤ ±0.02mm, good flexibility |
| Medium: 0.3mm - 1.2mm | Architectural decoration (ceiling panels, wall cladding, door panels), advertising light boxes | Thickness deviation ≤ ±0.03mm, flat surface without waves | |
| Thick: 1.2mm - 3.0mm | Transportation parts (automotive trim, trailer panels), outdoor billboards, cabinet frames | Tensile strength ≥ 150MPa, good stamping performance | |
| Coating Parameters | Thin Coating: Total thickness 20-30μm (primer 5-8μm, topcoat 15-22μm) | Indoor decoration (interior wall panels, furniture panels), small home appliances | Adhesion ≥ 4B, pencil hardness ≥ 2H |
| Standard Coating: Total thickness 30-40μm (primer 8-10μm, topcoat 22-25μm) | Outdoor architectural decoration, medium-sized home appliances, signage | Color difference ΔE ≤ 1.5, neutral salt spray test ≥ 500h | |
| Thick Coating: Total thickness 40-50μm (primer 10μm, topcoat 25-30μm, backcoat 5-10μm) | Harsh environment applications (coastal architectural cladding, industrial workshop walls) | Neutral salt spray test ≥ 1000h, weather resistance test ≥ 2000h | |
| Width & Length | Standard Width: 1000mm, 1220mm, 1500mm, 1600mm | Batch production of architectural materials, home appliances, and signage | Width deviation ≤ ±0.5mm, no edge warping |
| Custom Width: 500mm - 1600mm; Length: 50-3000kg/roll | Special-sized architectural projects, customized home appliances, and transportation parts | Uniform coil tension, no creases or scratches | |
| Alloy Types | 1050/1060 Alloy (≥ 99.5% Al) | Indoor decoration, home appliances, and low-stress applications | Excellent ductility, easy to process into complex shapes |
| 3003 Alloy (with Mn 1.0-1.5%) / 5052 Alloy (with Mg 2.2-2.8%) | Outdoor decoration, transportation parts, and high-stress applications | Enhanced corrosion resistance and tensile strength |
| Alternative Material | Advantages of Polyester-Coated Color Aluminum Coil | Key Reason |
| Galvanized Steel Plate | Lighter weight (1/3 of steel), better corrosion resistance, richer colors, and no rust | Galvanized steel is prone to rust after the zinc layer is damaged; aluminum substrate has natural corrosion resistance, and the polyester coating enhances protection. |
| Solid Wood | No deformation, no moth-eaten, water-resistant, fire-resistant, and longer service life (15-20 years vs. 5-10 years of wood) | Wood is easily affected by moisture and temperature, leading to deformation and moth-eaten; polyester-coated aluminum is stable in physical properties and not affected by the environment. |
| Ceramic Tile | Lighter weight (reduces building load), easier to install (no need for cement bonding), and better formability (can be bent) | Ceramic tile is heavy and brittle, easy to break during transportation and installation; it cannot be processed into curved shapes. |
| PVDF-Coated Aluminum Coil | Lower cost (about 30-50% of PVDF), sufficient performance for general applications, and more color options | PVDF coating has better weather resistance but higher cost; polyester coating meets the needs of most non-harsh environment applications at a lower cost. |
They are widely used in home appliance panels (like refrigerators and washing machines), indoor and outdoor architectural decorations (including ceilings, wall cladding, and door panels), advertising signage, light boxes, and transportation parts.
Polyester coating (PE) is highly cost-effective, costing about 30% to 50% less than PVDF. It offers excellent color options and sufficient durability for indoor use and standard outdoor environments, while PVDF is typically reserved for extremely harsh outdoor conditions due to its higher cost.
Polyester-coated aluminum coils are significantly lighter (about 1/3 the weight of steel), offer superior natural corrosion resistance, will not rust even if the coating layer is scratched, and provide a wider variety of vibrant finish options.
Standard coating thickness ranges from 30-40μm (with an 8-10μm primer and 22-25μm topcoat) which is suitable for standard architectural decoration. Thin coatings (20-30μm) are ideal for indoor use, while thick coatings (40-50μm) are optimized for demanding industrial environments.
Yes. Standard widths include 1000mm, 1220mm, 1500mm, and 1600mm. However, custom widths ranging from 500mm to 1600mm and substrate thicknesses from 0.15mm to 3.0mm can be supplied according to specific project demands.
