A practical guide to architectural aluminium finishes

Choose the process for the application

Anodising becomes part of the aluminium surface, while powder coating adds a cured coating in a broad colour range. Decorative brushed, steel-look and wood-effect options support specific visual directions but still need appropriate care and specification.

Approve a physical reference

Colour names and digital images are not reliable final references. Review a physical sample under relevant lighting and agree acceptable variation before ordering production quantities.

• Record colour, gloss and texture.
• Use one approved control sample.
• Keep visible batches coordinated where practical.

Design for cleaning and drainage

Even durable finishes need sensible detailing. Avoid water traps, isolate incompatible materials and establish a cleaning regime suited to the exposure and finish supplier’s recommendations.
