Aluminium coating
We run all three lines in-house — vertical (PVDF), powder and heat-transfer. Centred on high-weatherability PVDF coating, the standard for high-rise exterior windows, we finish the surface treatment each job calls for on our own lines.
Three independent lines,
surface treatment to suit the purpose
We run all three lines in-house — vertical (PVDF), powder and heat-transfer. Centred on high-weatherability PVDF coating, the standard for high-rise exterior windows, we finish the surface treatment each job calls for on our own lines.
All three lines share the same backbone — pre-treatment → coating → drying and curing → inspection — and differ in the paint and the curing method. Heat-transfer sublimates a wood grain into a powder base coat.
- 02-A Vertical (PVDF) coating — high-weatherability fluoropolymer coating on a vertical hanger line · 50 t/day
- 02-B Powder coating — integrated pre-treatment, electrostatic coating and baking line · 10–12 t/day
- 02-C Heat-transfer (wood grain) — wood-grain surface finish pigmented into the coating film · 4–5 t/day
Three independent lines
Vertical (PVDF) coating
High-weatherability fluoropolymer coating on a vertical hanger line. For residential and high-rise exterior windows — colour and gloss that last.
Powder coating
Integrated pre-treatment, electrostatic coating and baking line. High weather and corrosion resistance, with wide freedom in colour and texture.
Heat-transfer (wood grain)
Wood-grain surface finish pigmented into the coating film. Related patent history supports the wood-grain finishing process.

Not a film —
grain set into the coating
A surface finish that pigments the wood grain directly into the coating film with paint. Contact us to select specifications suited to the application and exposure conditions.
The wood grain is rendered directly on the aluminium profile surface with paint. The pattern is pigmented into the coating film. Specifications depend on the intended application and environment.
Our own technology, based on related patent history, is applied to windows, doors, louvres and exterior panels through to interior finishes.
