02 · System anatomy
The material is not a single surface.
An engineered aluminium frame or component protected by an alloy-compatible pretreatment and cured powder-coat system. Alloy, welds, drainage, isolation and coating form one exposure-specific build.
01Decorative top surface
Layer function
Polish, patina, plating, PVD, clear coat or powder establishes colour, gloss and touch response.
How to verify
Name the exact finish route, product/layer build and brushing direction.
02Pretreatment / undercoat
Layer function
Cleaning, conversion coating, strike layers or primers create adhesion and corrosion resistance.
How to verify
Require process declaration and adhesion/corrosion evidence for the exposure.
03Base metal
Layer function
Stainless, mild steel, brass, bronze, copper or aluminium determines strength, corrosion and repair.
How to verify
Mill/material certificate or explicit alloy/substrate declaration.
04Fabrication / joint
Layer function
Tube/plate thickness, welds, braze, fasteners, drains and isolators control structural and corrosion performance.
How to verify
Shop drawings and first-off expose welds, inside returns, edges and dissimilar-metal interfaces.

Material specimen detail
Powder-Coated Aluminium as a physical material sample.
This specimen view focuses on the surface, edge and construction of Powder-Coated Aluminium. No furniture product is presented here; the approved physical sample remains the reference for final colour, texture and finish.
Project notes
From sample to production.
01
What to specify
Specify both the base metal and decorative finish. “Brass finish” may mean solid brass, brass-plated steel, PVD stainless or paint; performance and cost differ substantially.
02
Fabrication & detailing
Coordinate weld locations, wall thickness, drainage, concealed fixings and dissimilar-metal isolation. Complete grinding and polishing before the final decorative coating.
03
Colour & finish approval
A signed metal control sample defines tone, texture, gloss and brushing direction. Large fabricated pieces can read differently from small chips, so full-size samples may be requested.
04
Care & maintenance
Clean with a soft cloth and mild neutral detergent, then dry. Avoid abrasives, chloride cleaners and aggressive polish; coastal pieces require more frequent fresh-water cleaning.
Specification note
This page is a preliminary material-specification guide. Current product data, test reports, the physical material sample and the intended application system must be approved for each project before ordering or manufacture.
