Decking wood species appearance

Our decking hardwoods range in colour from pale cream (Vitex), honey-brown to medium brown (Garapa and Tonka) through to dark red-brown (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 factory clear deck oil on all four faces prior to delivery. This coating acts as an artificial coat to provide additional stability and slow the weathering process during the initial stages of the deck acclimatising. However, it does not prevent the silvering process as it contains no pigments.  

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

All of Rosenfeld Kidson's Garapa, Kwila and Tonka hardwood carries FSC 100% environmental certification. Our Vitex is sourced from no-controversial, community based operations, as per the rules and guidelines defined by the NZITTG Charter. For further information, please see our Sourcing Policy.
