Vulcan Decking by Abodo is engineered for stability, performance and visual warmth in outdoor applications. The timber is sourced from rapidly renewable FSC® certified New Zealand plantation Radiata Pine and thermally modified using heat and steam, not harsh chemicals. This heat tempering process reduces resin content, improves dimensional stability and gives the timber a rich brown tone that gently silvers off over time if left uncoated.
Unlike many dense hardwood decking boards, Vulcan Decking is lighter, easier to cut and typically does not require pre drilling across most of the run. The reeded face gives underfoot grip and helps manage weathering, while the treated timber resists decay, fungal attack and termites, including in designated termite zones. This combination makes it suitable for Australian decks, pool surrounds and outdoor living spaces where people expect barefoot comfort, visual quality and service life.
For durability, Vulcan Decking is pressure treated with Abodo’s OPX system, a low VOC, organic preservative and water repellent. This provides H3 level protection for above ground use and supports a 25 year warranty against fungal decay and termite attack. With BAL 12.5 and BAL 19 suitability, clear installation guidelines and straightforward maintenance, Vulcan Decking is an accessible, compliant and future focused choice for builders, architects and homeowners.
