Surface Finish Options

You’ve thought about the colour you’re after, now you just need to consider the surface to really get the finish you’re after.


Powdercoating is a popular finish because of the wide colour range available and proven hard-wearing finish. Their wide use also is enhanced by the availability of high and premium-grade powders with advanced weathering abilities. 

A popular colour range is available, which offers a more economical choice because of volume efficiencies. Matt finishes rather than satin finishes have been introduced for most popular colours because of their better resistance to marking and scratching. 

A wide choice of powdercoat colours is available—see the colour chart below, noting that the colour palettes shown in the chart are a printed representation of the powder coat finish and therefore may vary somewhat to the actual extrusion colour. 

Note that light colours will retain their appearance better than dark or bright colours. Over the long term, powdercoatings will slowly degrade with a loss of gloss level apparent more so on external north-facing surfaces with darker or brighter coatings as these tend to absorb more heat and UV radiation. When judging colour consistency and integrity of finish, the accepted industry standard is inspection from a distance of two metres.

Frost Ultra Anodised

surface finish frost ultra andonised

Frost Ultra Anodised is an electrochemical process that builds up a protective layer on the surface of aluminium profiles. The metallic finish that is created does not peel, chip or flake and achieves good protection against heat, moisture, sunlight and atmospheric corrosion.

Silver (natural) is the main colour supplied, though black, bronze and champagne are also available.

Variability of colour, and visible aluminium grain are common features of Frost Ultra Anodised surfaces. These features are part of Frost Ultra Anodised and are not defects in the surface finish.

Frost Ultra Anodised gives a very durable and colour-fast surface finish that has been proven over many decades of use. A 10 year warranty is available on a job specific basis for 25 microns.

When judging colour consistency and integrity of finish, the accepted industry standard is inspection from a distance of two metres.
