Redefine Your Outdoor Living with Karri Decking
Karri is one of Australia's tallest and most majestic hardwood trees, growing almost exclusively in the south-west corner of Western Australia. This extraordinary height and straight growth habit produce Karri decking boards with unusually long, clean runs — delivering seamless, continuous deck surfaces with minimal joins that few other Australian decking species can match. With its warm reddish-brown heartwood, straight even grain, and a Janka hardness of 9.0 kN, Karri combines striking visual presence with genuine outdoor hardwood performance. Whether you're building an entertaining deck, a pool surround, a feature balcony, or an expansive outdoor living platform, Karri decking from JVS Timber delivers the structural density, weather resistance, and refined aesthetic that quality outdoor projects demand.
