Spotted Gum Timber Guide

Spotted Gum Timber Technical Information

Spotted Gum (Eucalyptus maculata)

Spotted Gum is one of Australia’s premium native hardwoods with a striking appearance and a high degree of natural durability and strength, making it an ideal timber for a variety of structural, exterior and interior applications. Architects and designers throughout the world value Spotted Gum timbers for their back-sawn grain structure, attractive markings and vibrant colour palette. The colour varies with this specie from pale grey browns and soft creams to a rich chocolate brown. A very tough timber, its frequent wavy grain can produce an attractive and highly valued fiddleback effect. The wood has a slightly greasy feel, a characteristic that aids machining and boring. Spotted Gum components that are 18mm thick or greater do not require fire retardant treatment for use in construction in bush-fire prone areas.

Spotted Gum is used in engineering applications such as wharf and bridge construction, railway sleepers, cross-arms and mining timbers. It is suitable for a range of building applications, such as posts and poles, framing, flooring, lining, decking and cladding.

• Dry Density: 950 kg/m³
• Janka Dry Hardness: 11 kN

The Janka rating is the hardness level given to each species. The higher the number, the greater the hardness.
The natural colour variation within a timber species is normal and one of its most appealing characteristics.
