British Standard BS1615 anodic coatings on aluminium.

Anodic coating is widely used for the treatment of aluminium and aluminium alloys. It provides an attractive decorative and protective finish.

Anodic coating ranges from 5 to 25 microns. It is recommended that for the best possible protection for exterior use an application of 25 microns be used.

After anodising, articles can be dyed to various colours.
