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.

Rosenfeld Kidson, as timber merchants acknowledge the importance of conserving the world’s greatest renewable resource.

We are pleased to advise that we carry Chain-of-Custody (CoC) certification that enables us to sell timber that carries either FSC certification (SGS-COC-006703) or PEFC certification (SGS-PEFC/COC-0993).

FSC certified timber and PEFC certified timber undergo independent, third-party audited certification procedures at every step of the supply chain. This provides designers, specifiers, architects and consumers absolute assurance that those forest and wood products labelled as FSC certified or PEFC certified originate from legal sources, which are managed to prescribed social, economic and environmental standards.

As a New Zealand timber supplier offering the country’s largest range and quantity of specialist certified timbers we believe that stocking FSC & PEFC certified timber is essential for our continued growth. A major part of our timber range has FSC or PEFC certification and we are continually striving to increase this.
