Etching

Etching produces a matt finish which will cover most extrusion lines, surface scratches and give an even coverage. If etching does not cover the extrusion lines, on your aluminium extrusions, we can also offer polishing which will blend in the surface prior to etching.

Semi-Bright

This produces a matt finish to the aluminium but with a brighter appearance when compared to just etching.

Chemical Brightening

This produces a bright decorative finish to the work and is often used to create a high degree of reflectivity often required for the lighting industry.

Please note that not all aluminium alloys are ideally suited to chemical brightening.  If you require any further advise on this matter please feel free to contact us on 0121 622 1850.
