Surface treatment

Five finishes, all in our own workshop, so colour and quality stay under one roof.

Anodizing grows a hard oxide layer into the metal; electrophoresis adds a clear or tinted acrylic layer on top; powder coating gives any RAL colour; PVDF (fluorocarbon) coating keeps its colour longest outdoors; and wood grain transfer prints a timber pattern into a powder-coated base. All five are done in-house.

Which finish for which job?

Questions

Which finish lasts longest outdoors?

PVDF (fluorocarbon) coating holds colour and gloss longest under UV and coastal exposure, which is why it is specified for curtain walls. Powder coating is the most common choice for windows and doors.

Can you match a RAL colour?

Yes. Powder and PVDF coatings are available in RAL colours in gloss, semi-gloss or matte.

Anodizing or powder coating?

Anodizing keeps the metallic look and is very hard; powder coating offers any colour and a thicker protective layer. Industrial and solar profiles are usually anodised; windows and doors are usually powder coated.
