Frequently Asked Questions
What is the difference between PE and PVDF coating?
PE (polyester) is economical and ideal for interior and short-to-medium exterior use (10–18 years). PVDF (Kynar 500) offers superior UV and chemical resistance for premium facades and coastal projects (15–25 years).
Can you match a specific RAL or Pantone colour?
Yes. We match any RAL colour and most Pantone references, including metallic finishes, and send physical samples for approval before production.
What thickness is used for ACP?
ACP skins typically use 0.21–0.50 mm PVDF colour coated aluminium; we slit to the exact ACP panel width you require.
What is your MOQ and lead time?
MOQ is 3–5 tons per colour/spec. Lead time is generally 20–30 days. See current colour coated aluminium coil options.
