The Natural Strength of Blackbutt Timber
Blackbutt is a premium Australian hardwood known for its strength, durability and clean, contemporary appearance. Featuring a generally straight grain and even texture, it delivers a refined aesthetic suited to modern architectural designs and outdoor living spaces. Its heartwood ranges from pale straw and golden honey tones through to light brown, sometimes with subtle pink hues, creating a bright and natural finish that complements a wide range of materials.
With a typical density of 800–900 kg/m³ and a Janka hardness rating of approximately 9.3kN, Blackbutt is a strong and durable timber capable of withstanding heavy wear and high-traffic environments. Its Class 1 above-ground durability rating provides exceptional resistance to decay and long-term outdoor performance, while Class 2 in-ground durability ensures reliable structural use.
Blackbutt is also well suited to bushfire-prone areas, with proven fire resistance and suitability for BAL-29 applications. Its natural resistance to wear, moderate termite resistance and long service life make it an excellent choice for demanding Australian conditions.
Why Choose Blackbutt for Your Projects?
Blackbutt is naturally suited to coastal environments, high-traffic areas and large-scale commercial applications where strength and stability are essential. Its structural integrity makes it widely used for framing, posts, beams and exterior construction, particularly throughout New South Wales and Queensland.
Beyond performance, Blackbutt is valued for its consistent grain and light natural colouring, which helps create open, modern spaces. It machines and finishes well, readily accepting stains, paints and coatings, making it a preferred timber among builders and woodworkers seeking both durability and ease of installation.
Sustainably harvested and processed in Australia, Blackbutt supports responsible construction while delivering reliable performance and visual appeal.
