Anodising Overview

When any new aluminium surface is exposed to air, it immediately combines with oxygen in the air to form Aluminium Oxide. Although this protective layer is only one five thousandths of a micron thick, it provides good protection against corrosion.

The anodising process uses aluminium’s affinity towards oxygen to create a thicker oxide layer in a controlled manner on the mill finish metal.  Anodising therefore provides greater protection.

We recommend anodising as soon as possible after manufacture of an extruded section. If this isn't possible, materials must be stored in a clean, dry environment. Any change in the surface of an extruded section, even if you can't see it, may affect the metal’s response to anodising or its final appearance.

For long term durability, use only gentle cleaning products and soft brushes.
