Blackbutt timber (Eucalyptus pilularis) is an iconic Australian hardwood species, grown along the eastern coast from southern Queensland into New South Wales. It has earned a strong reputation for structural strength, weather-resistance and aesthetic appeal. With a heartwood that ranges from golden yellow to pale brown (occasionally with a pinkish hue) and a generally straight, even grain, it offers a premium appearance while delivering high performance. At Franz Building Supplies, we stock reliable timber supplies for landscaping, construction and renovation projects across Perth.
The benefits of blackbutt timber
Outstanding durability & longevity
It is rated as Durability Class 1 for above-ground use (life expectancy over 40 years) and offers strong fire resistance (suitable for bush-fire zones) and natural termite resistance, making it a go-to choice for challenging exterior and structural applications.
Natural fire & termite resistance
Due to its density, structure and extractives, Blackbutt timber is one of the preferred hardwoods in bushfire-prone zones (BAL-rated) and has inherent resistance to lyctid borer and termite attack.
Warm aesthetic & structural versatility
With a uniform straight grain, golden to pale brown colour and excellent machineability, Blackbutt works beautifully for visible structural elements, cladding, outdoor joinery and more, providing both form and function.

Blackbutt is a Class 1 durability timber above ground and Class 2 in ground, capable of lasting 40 plus years in above ground applications when installed correctly. A minimum clearance of around 400mm from ground level is generally recommended to allow airflow and support long term performance. We can quote and supply Blackbutt decking and associated products, however installation is completed by others and conditions of build and maintenance will influence lifespan.
Blackbutt is harvested from native forests as well as plantations in eastern Australia, and many supplies come from responsibly managed sources. Its long service life means fewer replacements and reduced resource consumption over time.
Yes. Blackbutt is one of the hardwoods approved for use in areas with elevated bushfire-attack levels (such as BAL-29 in some applications) due to its density and fire-resistant properties. It also exhibits natural resistance to termite and lyctid borer attack.
Yes. Blackbutt is a naturally termite-resistant hardwood, thanks to its density and inherent properties that make it less attractive to termite attacks compared to many softer timbers. While no timber is completely termite-proof, choosing blackbutt timber provides an added level of long-term protection.
