Once predominantly used only as a structural timber, considering its natural beauty and sheer strength, its not surprising Spotted Gum has found favour in many aesthetic, and architectural applications with extremely impressive results.
Because of its significant versatility and durability you will find Spotted Gum used in a wide variety of applications. From building and construction, including structural components, flooring, cladding, and decking, right through to furniture (indoor and outdoor), landscaping, boat building, poles, beams, the list goes on.
Widely used for power poles, bridge timbers and general construction, Spotted Gum is one of the most widely available recycled timbers in Australia today.
In the future this species will become more readily available from Australian hardwood plantations as a result of its growing popularity.
