Blackbutt is a coarse-textured, strain-grained timber typical of the harsh Australian coastal climate in which it thrives. It’s hard and tough but relatively easily worked – qualities that have made it a popular choice for decking. Blackbutt is honey blonde coloured and its sapwood is resistant to borers.
Heartwood pale brown, but northern material may sometimes display a pinkish tinge. Sapwood distinctively paler.
Texture medium and even. Grain usually straight. Gum veins common.
