Blackbutt is derived from the tree’s appearance after bushfire, which is marked by a significant darkening of its butt. It is also known as coastal blackbutt to distinguish it from the tableland species, New England blackbutt.
Blackbutt is an ideal plantation timber due to its rapid growth and versatility. In New South Wales and southern Queensland, it is a commonly available commercial hardwood species and is tend to be used for construction frameworks.
Gold to grayish-brown heartwood often contains a slight pinkish hue. It has a pale appearance and is resistant to lyctid borer attack, but it’s not always easy to tell the sapwood from the heartwood. In terms of texture and grain, blackbutt is generally straight and pleasant to handle.
Surface checking can cause paint issues with blackbutt, which can be stained, painted or polished. Younger regrowth wood is less likely to cause adhesive problems because of the high extractive content. Weathered painted surfaces can also get stained with these extractives. Steam bending with Blackbutt is not good.
There are seven hardwood timber species that have been found to be suitable for building homes in bushfire areas by the Building Commission in NSW (providing that it has a thickness greater than 18mm).
In addition to blackbutt framework, decking, flooring, poles, and flooring, blackbutt is a strongest, most durable hardwood.
