Blackbutt Timber


Eucalyptus pilularis

Blackbutt timber is a strong and durable hardwood which is commonly used for structural and exterior applications. It’s also often used for flooring and other interior features when the colour requirement is light and neutral.

Blackbutt is an Australian hardwood which grows in the coastal regions of New South Wales and Queensland and is so-named due to the tree’s appearance after a bushfire, where the butt of the tree is significantly darkened.

Blackbutt Applications

This versatile, attractive hardwood can be used in structural, exterior or interior applications. As a dar hardwood, it can offer a sleek and smooth appearance for battening, office fit-outs, stairs and screening projects.

From Blackbutt flooring and furniture to exterior or structural use in decking, landscaping, timber framing, cladding, lining boards or joinery, this highly durable timber will stand the test of time.

Physical Properties of Blackbutt Timber

Versatility and strength make Blackbutt cladding or Blackbutt timber framing a good choice in home construction. As a hardwood, Blackbutt has a hardness rating of 9.1 and is naturally resistant to termites and natural borers due to its high density.

Blackbutt timber has proven durability in harsh Australian conditions and is the ideal choice for use in areas prone to bushfire. It is one of only seven hardwood timber species approved by the Building Commission in Victoria for home construction in bushfire areas.

Blackbutt’s attractive colouring ranges from cream to pale brown, occasionally with a pinkish hue. It takes stain, oil or polish well but tends to be a poor base for paint due to the likelihood of surface checking. This allows for some amazing applications where the Blackbutt is stained to increase it’s durability and accentuate it’s natural timber aesthetic.

When allowed to weather naturally, Blackbutt decking or timber facades turn a stunning silvery grey, which is a popular trend in outdoor timber applications.

The even texture and generally straight grain of Blackbutt timber flooring provide a seamless transition from inside to outside when used to take floorboards through to decking on the same level.
