Finishes

• Anodised aluminium finishes – an electro-chemical process that thickens the natural oxide layer for outstanding UV and abrasion resistance. Variants include natural anodised aluminium finish, bronze tones and coloured options.
• Brushed finishes – mechanical brushing creates a directional grain ideal for architectural highlights and appliance fronts. Search for an aluminium brushed finish when you want subtle texture without glare.
• Mill finish – straight from the extruder, mill aluminium is economical but needs sealing in harsh environments.
• Wood-finish aluminium – powder-coat sublimation technology produces realistic timber patterns, perfect for wood finish aluminium windows that never need staining.
• Mirror polish – a multi-stage mechanical polish delivers a near-reflective surface. Knowing how to get a mirror finish polish on aluminium is specialist work, so source from trusted fabricators.

On ArchiPro you can filter by more than colour chips. Key data points include:

• Marine rating – essential for projects within 500 m of breaking surf.
• Micron thickness – anodising ≥25 µm meets premium exterior specifications.
• Warranty length – leading suppliers back finishes for 15–30 years.
• Coating supplier accreditation – Qualicoat or ISO certifications signal tighter process control.

Exterior aluminium components must satisfy Building Code clause B2 Durability. Specifying an anodised coating of the correct thickness or a certified powder coat system helps demonstrate that 15-year requirement for claddings and joinery.

Thanks to its versatility, aluminium appears across multiple finish categories. Explore complementary products in our Products hub, or dive directly into:

• Flooring finishes – aluminium nosings and trims.
• Tiles & Stones – edging profiles and recessed skirtings.
• Wall & Ceiling Finishes – batten systems and feature panels.
• Paints – primers designed to bond to aluminium substrates.
• Acoustic finishes – perforated aluminium panels with specialist backings.
• Stains & Treatments – clear coats and protective sealers.
• Solid surface – hybrid panels pairing aluminium skins with composite cores.

1. Match alloy and finish. Not every alloy accepts every treatment. 5000-series marine aluminium, for example, cannot achieve a bright clear anodise.

2. Request test reports. Ask suppliers for salt-spray and UV fade results to back up claims.

3. Consider after-cut protection. Even the best aluminium surface finish leaves raw edges when profiles are drilled or mitred. Specify onsite touch-up kits.

4. Factor in differential weathering. Dark colours absorb more heat and may age faster on north-facing elevations.

Anodised surfaces are low-maintenance: rinse twice yearly with fresh water. Powder-coated facades need gentle detergent cleaning to prevent chalking, especially in industrial zones. Never use steel wool on a delicate brushed aluminium finish-micro-fibre cloths are safer.
