Sulphuric anodising is an electrolytic treatment for aluminium that produces a coating of aluminium oxide. This coating exhibits excellent corrosion resistance and can be dyed in a variety of colours. (Clear/natural anodising is available at the present. We will update our website as soon as more colours become available.)
The coating is available up to around 25 microns in thickness (beyond this thickness, hard anodising is required). Clear / natural colour coatings are typically 5 to 15 microns and coloured coatings are typically 10 to 25 microns.
