Production Process

Aluminum coil raw material feeding → Multi-cycle degreasing and alkali cleaning → Chromium-free environmental passivation treatment → Constant temperature hot air drying → PVDF primer roller coating & high temperature curing → PVDF top coat coating & secondary baking → PVDF clear coat coating & third curing → Natural cooling → Surface quality inspection → Protective film lamination → Precision slitting → Fixed-length cutting → Stacking & dust-proof export packaging.

Each batch will undergo gloss test, color difference test and coating adhesion test before delivery to guarantee stable outdoor weather resistance.

FAQ

Q1: What is the difference between PVDF and PE coated aluminum strip?

A: PE coating is suitable for indoor use with 5-8 years service life; PVDF fluorocarbon coating has super weather resistance, UV resistance and corrosion resistance, 20+ years outdoor service life, specially designed for high-end building exterior projects.

Q2: Is PVDF aluminum strip suitable for coastal areas?

A: Yes. PVDF coating has excellent salt spray resistance and anti-corrosion performance, can resist marine humid and salt fog environment, is the first choice for coastal building window and curtain wall systems.

Q3: Can you customize special width and color?

A: Fully supported. We can slit any width from 10mm to 300mm according to customer requirements, and customize all RAL colors, metallic colors and wood grain finishes.

Q4: Will bending affect the weather resistance of PVDF coating?

A: No. The PVDF coating has excellent flexibility, conventional bending and profiling will not damage the paint film, and the weather resistance remains stable after forming.
