Australian Premium Native Hard Suited To Wharf & Marine Construction

Grey ironbark is a premium native hardwood that has been well regarded as a high-quality timber in Australia throughout human history. Indigenous Australians used it to make spear throwers and boil its bark for treating sores. 

A particularly hard, strong and durable timber, commonly used for wharf and Marine construction above and below the waterline, Decking, Fencing, Exterior Cladding and Exterior Furniture.

The grey ironbark is a medium-sized tree of 30 to 50m with a stem diameter of 1.5m. The bark is hard, coarse, with deep furrows and ridges, ranging from dark brown to black in colour and grows even on the small branches. 

The timber's appearance ranges from reddish to dark brown heartwood. The sapwood is lighter in colour and is 20mm thick on average. The grain is usually tight and straight and no distinctive figure is encountered.
