Another hardwood that is great for timber flooring or decking for your Brisbane home is Ironbark. Ironbark, also called Grey Ironbark, comes from the Eucalyptus Paniculata tree and has a durability rating of 1. Ironbark is not only hard and durable, but it is very heavy. This makes it perfect for structural use.
Due to its weight and density, it is not used for a lot of smaller, precision work, but it is great for big jobs. It is used for decking, flooring, handrails and outdoor framing around the home. Industrial applications include shipbuilding, construction, railway sleepers, piles and poles.
Ironbark is native to New South Wales in coastal areas with high rainfall, mainly from Bulahdelah to Bermagui. Its colours can vary considerably, anywhere from dark red to dark brown to pale brown, though most of our Ironbark tends to be red. Ironbark usually grows 20-30 metres tall, but has been known to grow as tall as 56 metres with a diameter of 1.96 metres.
Ironbark sapwood is not susceptible to lyctid borers while the heartwood is class 3 resistant. It is resistant to termites above ground and the durability rating of 1 applies both above and below the ground.
We mentioned density and weight earlier. Ironbark is difficult to work with, but provides great results. If you are trying to complete a deck in one weekend, we would recommend using Merbau. Ironbark is difficult to nail and to plane, and the fact that it is so heavy makes it a lot harder to hold in place while nailing.
The upside to Ironbark is that if you are able to work with it, your deck or flooring will seemingly last forever. The grain is interlocked. The texture can be coarse, but even. It makes very solid flooring, but a gloss finish is recommended due to the coarse texture.
