Natural Blackbutt timber decking is a popular choice for Australian outdoor spaces, valued for its light coastal colour tones and dependable performance. Known for its strength and versatility, Blackbutt suits everything from residential decks to large entertaining areas, delivering a clean, timeless finish that complements both modern and traditional designs.
Stable and Reliable
Blackbutt timber offers excellent stability, helping boards perform reliably through Perth’s temperature changes. Its density and structure reduce excessive movement when correctly installed, making it well suited to exposed decking areas.
High Hardness for Everyday Use
With a hardness rating of around 9.1, Blackbutt decking handles foot traffic, outdoor furniture and daily wear with confidence. This strength helps maintain the surface appearance over time, even in busy entertaining spaces.
Naturally Suitable for Bushfire Zones
Blackbutt is one of the few Australian hardwoods recognised for use in bushfire prone areas, achieving ratings up to BAL 29 without chemical treatment when installed correctly. This makes it a practical option for many WA coastal and regional builds.
