Spotted Gum Timber Flooring Perth
The Spotted Gum is a tall tree growing up to 50 metres in height and 1.3 metres in diameter, which grows along the east coast of Australia from the New South Wales-Victorian border, extending to the Maryborough district in south east Queensland. Spotted Gum is a large hardwood and the tree sheds elliptical strips of bark as it weathers, deriving its common name from the mottled or spotted appearance. It has small white flowers which appear from winter to spring.
Spotted Gum is currently the highest volume native hardwood harvested in Queensland with future supplies well secured.
The heartwood is durable and ranges in colour from very pale brown through to dark brown with slightly orange or green tints and some lighter variations. The sapwood is distinctly paler than the heartwood. Often interlocked, the grain appears wavy, featuring a distinctive ‘fiddleback’ figure and gum veins.
Spotted Gum is a very durable native timber and is classified for inground use as class two with a life expectancy of 15 to 25 years. Above-ground applications are class one which classifies the species as having a life expectancy of over 40 years.
The timber has a natural resistance to termites and
will readily accept paint, stain and polish. It is naturally
fire resistant and meets the required parameters under Australian Standard AS395 as a timber that does not have to be subjected to fire retardant treatment. This makes Spotted Gum a popular choice as an outdoor decking timber.
Spotted Gum is sought after by consumers and specifiers alike for its striking colour and for its density. It is used widely in aesthetic and structural applications.
Spotted Gum is very dense with excellent mechanical properties. Its level of hardness (with a janka rating of 11) makes Spotted Gum popular for commercial applications such as gymnasiums and basketball courts. It is also used
as unseasoned timber in general house framing and as seasoned dressed timber in cladding, linings and joinery as well as fencing, landscaping, retaining walls and in structural plywood and hardboard.
Spotted Gum is the main Australian species used for tool handles which are subjected to high impact forces, such as
axe handles. It is very popular for flooring and decking as well as in other structural and aesthetic applications such as boat building (keel and framing components, planking, decking), coach, vehicle and carriage building, agricultural machinery, sporting goods (baseball bats, croquet mallets, spring and diving boards, parallel bars) and bent work. It has been used for many years to make butcher’s blocks, meat skewers, mallet heads, ladders, wheel spokes, wine casks and broom handles.
