A wide range of durable colours and styles are available for aluminium extrusions & fabricated components.

G.James offers a number of surface finishes including powder coating, anodising, and Effecta® finishes in a range of colours.

G.James recommend arranging to view physical colour samples of aluminium colours. Samples should be viewed under both natural and artifical lighting conditions before finalising your selection.

Powder Coating

Powder coating is an electrostatic process whereby electrically charged paint particles in the form of a powder are sprayed onto the surface of pre-treated aluminium to achieve a highly durable finish.

View our range of powder coated colours below, or arrange to view a physical sample of colours.

Aluminium Effecta

Effecta® is a patented surface finishing process that replicates the colour and appearance of timber onto aluminium, while still offering all the benefits of low maintenance aluminium.

View our range of Effecta® styles below, or arrange to view a physical sample of aluminium styles.

Anodised Aluminium

Anodising enhances the natural metallic lustre of aluminium while applying durable and vibrant colour through an electrochemical process.

View our range of anodised colours below, or arrange to view a physical sample of aluminium colours.
