Spotted Gum Timber


Australian Eucalypt family corymbia maculata.

Spotted Gum Timber is an Australian hardwood considered perfect for building and construction.

It is in plentiful supply and made up of four different species. The trees grow sustainably along Australia’s east coast, from the northern part of Queensland all the way down to Victoria.

Spotted Gum Applications

Our Queensland Spotted Gum decking and flooring is incredibly popular, and as a dressed hardwood timber it can be used for railings, poles, posts, pergolas, screening and other architectural features. Heavy duty uses include industrial structural applications, including bridge, wharf and boardwalk construction, shipbuilding, lining and Spotted Gum cladding.

Physical properties of Spotted Gum

Spotted Gum is a distinctive light brown to dark chocolate hardwood with some reddish tinges. It often features a variable, wavy grain that can produce an attractive fiddle back figure. It is favoured by architects and interior designers for its back-sawn grain structure, attractive markings and rich colour palette.

Spotted Gum is exceptionally versatile, has a high level of natural durability and strength with a Janka (or hardness) rating of 11. Due to its high density, Spotted Gum Timber flooring or decking is unlikely to experience much movement and shrinkage.

Spotted Gum machines well and can be used with standard fittings and fastenings. It readily accepts paint, stains and polish and is a minimal staining timber that is less prone to bleed-through of tannins than other species.Spotted Gum responds well to oils for the purpose of staining. Whether this is in the form of water-based or oil-based decking oils, Spotted Gum timber can be finished with timber coating products that will help you sustain the natural look of your Spotted Gum. Timber coating products are helpful in building on the natural appeal of timber and protecting them from the elements too.

Spotted Gum will stand the test of time and when used outdoors it will resist the elements. Its strength and durability make it perfect for heavy engineering, infrastructure or structural projects.

Due to its versatility, strength and level of durability, Australian Spotted Gum is a very well sought-after option in architecture and construction. It also draws a slightly higher price tag than some other Australian Hardwoods.
