The familiar name blackbutt, happened due to the tree’s look after bushfire, whereby the buttress (or butt) was considerably darkened. It is also known as coastal blackbutt to differentiate it from the tableland species, New England blackbutt.
Due to its quick development and adaptability, blackbutt makes a good plantation wood. It is a commonly available commercial hardwood species in New South Wales and southern Queensland, commonly made use of for building structure.
The heartwood varies from golden yellow to pale brown, although sometimes a slight pinkish color might exist. The sapwood, which is not always easy to identify, is much paler in look and is resistant to attack by lyctid borer. Blackbutt has an even structure and typically straight grain making it appealing for indoor usage applications.
Blackbutt can be stained, painted or polished but there can be concerns with painting because of its tendency to surface check. The high extractives of mature wood can result in troubles with some adhesives, however this is much less of a concern with young regrowth wood. These extractives can also lead to staining on painted surface areas exposed to the weather condition. Blackbutt machines well however is just fair for steam flexing.
Blackbutt Timber offers excellent fire resistance and is among seven hardwood timber types that was found to be appropriate by the Building Commission in Victoria for home construction in bushfire areas (granted it has a thickness greater than 18mm).
A strong, long lasting hardwood, blackbutt can be utilized for an array of structural, exterior and indoor applications including framework, decking, flooring and poles/posts.
