Ironbark Timber Specifications

Hardwearing, strong & durable

As premium Australian hardwoods, Grey and Red Ironbark are known for their hardwearing qualities, strength and durability.

Ironbark trees are named after their thick, compact and hard bark. They grow in Victoria, New South Wales and Queensland.

Physical Properties and benefits

Ironbark timbers are very distinctive. Red Ironbark heartwood is a deep dark red to red-brown colour with a distinctive, contrasting pale yellow sapwood. It has a fine, even texture with an interlocked grain.

Grey Ironbark’s colour palette can vary greatly. Its sapwood can be almost white, setting it off from heartwood that ranges from light grey to pale brown to dark chocolate, with occasional red tones. The texture is fine and even, and the grain usually straight.

The hardwearing timber is ideal for high traffic areas making Ironbark decking and flooring popular in commercial and domestic builds.

Ironbark timbers have high density levels with strong natural resistance to lyctid borers and termites. Their density can make the timbers difficult to work with, particularly when it comes to finer details. However, it also makes them perfect for use in engineering and construction projects.

Applications

Ironbark timber has a broad range of applications due to its incredible strength and durability.

Grey Ironbark can be used for structural timber, house framing, fencing flooring, stairs, decking and furniture.

Red Ironbark timber is commonly used in house framing, decking and flooring. Its beautiful red tones can present well in indoor and outdoor furniture and cabinetry.

Red Ironbark is also a popular choice for engineered structures that require excellent durability and strength, such as wharf and bridge construction, poles and piles.
