To enhance and subtly change the appearance of the finish prior to anodising, the aluminium may be Mechanically Textured or Chemically Pre-treated.

Mechanical Textures.

Beadblasting
A textured finish. The appearance can be varied to produce a very fine texture through to a coarse 'industrial look' finish. Can be used in conjunction with brightening to produce a subtle lustre.

Brushing
A popular textured finish particularly suitable for facias and enclosures. Can be used in conjunction with beading, etching and brightening to vary the appearance of the finish.
Note ! A very coarse brushed finish does not give a good key for printed legends.

Polishing
A shiny finish achieved by mechanical hand polishing Not all alloys give a good gloss when polished - please seek advice before selecting your alloy.

Chemical Pre-treatments.

Etching
Produces a matt finish

Brightening
Produces a bright finish. Can be used in conjunction with mechanical textures to vary the appearance of the component. Not all alloys brighten well.

Please refer to our alloy information data sheet for details of suitable alloys.
