Description of Red Ironbark Timber

Nearly as tough and resilient as its close cousin the grey ironbark, red ironbark trees are an evergreen eucalyptus that grows to approximately 30 meters tall. Often called a mugga, mugga ironbark, or pink ironbark. The tree is especially hardy and can grow in some of the most desolate types of sandy soils.

Situated sporadically but widely in the eastern and southern regions of Australia and most commonly found in north-central Victoria, the western plains and slopes of New South Wales and southeast Queensland. Red ironbark trees have deeply furrowed bark so dark as to be almost black, though its upper limbs are smooth and appear closer to white in colour. Thanks to its black bark, any red kino – or plant gum – that appears on it contrasts sharply and makes it quite conspicuous.

Most commonly pale to rich red this timber can also skew into the brown colourations, with a moderately coarse but interlocking grain.  Red ironbark is most suited for solid timber flooring, especially thanks to its dark, rich rosy colour and extreme durability.

Physical Properties of Red Ironbark

Dry Density: range 1090 kg/m³

Janka Hardness: 13.0 kN

With a density of 1090 kg/m³ and a Janka dry hardness score of an impressively high 13. Red Ironbark is nearly identical to its cousin Grey Ironbark, while being slightly easier to work with, and providing different ranges of colour and hue. In fact, part of Red Ironbark’s charm is its variegated hues (especially when placed next to one another in flooring). 

Despite these slight differences, red ironbark is incredibly resistant to termites as well, making it not just a handsome material but a highly durable one.

Despite these slight differences between it and other ironbark varietals, red ironbark is incredibly resistant to termites, making it not just a handsome material but a highly durable one. 

These properties are only a guide, as timber is a natural product there will be variations within any species. The Janka Dry Hardness rating measures the hardness of the wood. The higher the number the harder the wood.
