The strength and durability of this australian hardwood has seen it used throughout the ages as a preferred structural timber.

Red Ironbark is a very strong Australian hardwood that originated from QLD and NSW. Today Red Ironbark is used for all manner of building construction materials from poles to posts and beams and is 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 redbrown in colour. The sapwood by contrast is a pale yellow. The timber’s texture is fine with an interlocked grain.
