Aluminum Surface Finishing
For certain applications, aluminum extrusions require no more protection than its oxide film. If additional surface protection is desired, Otalum can assist. Our knowledge of alloys, properties and end-use enables us to help you match the correct finish to your project.

There is a variety of surface finish you can apply to your extruded profiles depending on the end-use of extrusions. Some of these surface treatments improve color, hardness, surface appearance and wear resistance.

Following are the most common-used surface finishes of aluminium extrusions in Otalum.

Aluminum Anodizing
Anodizing aluminium is an electro-chemical process that provides a stronger, corrosion resistant surface and preserves a “brand-new” appearance.

Aluminum Powder Coating
Powder coating is a surface treatment process used to give the surface corrosion resistance while providing a decorative appearance.

Aluminum PVDF Coating
A resin-based coating provides protection against weathering, ageing and pollution.

Aluminum Wood Grain Finish
Wood grain finish starts with powder coating and laminates a wood film in the surface of aluminium extrusion to provide a wood-look appearance.
