Product Description
PVDF Brushed Surface Coated Aluminum Coil for High-rise Building Facades
PVDF Brushed Aluminum Coil refers to a high-performance decorative aluminum material featuring a mechanically brushed surface texture and polyvinylidene fluoride (PVDF) coating. The product combines three essential technical dimensions:
Base Material
Utilizes aluminum alloy coils (typically 3003/5005 grades) with 0.2-3.0mm thickness
Surface Treatment
- Brushing Process: Mechanical abrasion creates directional grain patterns (straight/cross/random) with controlled roughness (Ra 0.4-1.6μm)
- Coating System: Multi-layer protection comprising:
- Conversion coating (chromate/chromium-free)
- Primer (epoxy/polyester)
- Topcoat (70% PVDF fluoropolymer)
Key Advantages
1. Superior Durability
- Long-lasting finish - Highly resistant to fading, chalking, and weathering, even in harsh environments
- Strong protection - Resists scratches, chemicals, and corrosion, maintaining appearance over time
2. Premium Aesthetic Quality
- Elegant brushed texture - Offers a sophisticated metallic look with customizable patterns
- Rich color options - Available in a variety of metallic and matte finishes to suit different design styles
3. Lightweight & Easy to Install
- Reduces structural load - Much lighter than stainless steel or solid metal panels
- Simplifies fabrication - Can be easily cut, bent, and formed for various architectural applications
4. Low Maintenance
Stays cleaner longer - Resists fingerprints, stains, and dirt buildup
Perfect for:
- ✔ Modern building facades
- ✔ Luxury interiors & furniture
- ✔ High-end appliances & transportation
