Today Red Ironbark is used for all manner of building construction materials from poles to posts and beams and its ideal for hardwearing areas such as flooring and decking. Whilst being quite hard to work with due to its density and hardness it also polishes to a high sheen and as such is frequently used for furniture, benchtops, bars and even in boat-building.
The heartwood is a deep rich dark red to red-brown in colour. The sapwood by contrast is a pale yellow. The timber’s texture is fine with an interlocked grain.
