PVDF Brushed Surface Coated Aluminum Coil For High-rise Building Facades

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
