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
a) Brushing Process:
Mechanical abrasion creates directional grain patterns (straight/cross/random)
with controlled roughness (Ra 0.4-1.6μm)
b) Coating System
Multi-layer protection comprising:
① Conversion coating (chromate/chromium-free)
② Primer (epoxy/polyester)
③ Topcoat (70% PVDF fluoropolymer)
Key Advantages
1. Superior Durability
a) Long-lasting finish – Highly resistant to fading, chalking, and weathering, even in harsh
environments.
b) Strong protection – Resists scratches, chemicals, and corrosion, maintaining appearance
over time.
2. Premium Aesthetic Quality
a) Elegant brushed texture – Offers a sophisticated metallic look with customizable patterns.
b) Rich color options – Available in a variety of metallic and matte finishes to suit different design styles.
3. Lightweight & Easy to Install
a) Reduces structural load – Much lighter than stainless steel or solid metal panels.
b) 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
