Decking wood species appearance

Our decking hardwoods range in colour from pale cream (Vitex and Yellow Cedar), honey-brown to medium brown (Garapa and Tonka) through to dark red-brown (Massa, Jarrah and Kwila).

All hardwood decking timber will weather to a silver grey if left to do so. The timber of some decking woods, like Kwila, will leach a dark coloured stain when wet.

All decking is available with an optional coat of FactoryOil on all four faces prior to delivery. This is available as either a clear coat or with a naturally coloured pigment to allow the timber colour to be maintained.

Decking timber lengths

Spread of lengths available and all supplied in random lengths (excl. finger-jointed). Lengths can vary, with most averaging between 2.7 to 3.0m, and up to 5.7m for finger-jointed kwila.

Decking timber sourcing

Species such as Garapa, Jarrah, Massa, Tonka, Saligna and Alaskan Yellow Cedar are from well managed and legal resources, most of which are independently certified as such. All imported Kwila carries third-party independently audited VLO (Verified Legal Origin) certification. See our Sourcing Policy.
