Ironbark Timber

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.

Is Ironbark Timber Easy to Work?

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 Timber or Kwila Timber.

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.

What Is the Biggest Upside of Ironbark Timber?

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 and the texture can be coarse, but even.

Ironbark Timber makes very solid flooring and with a a gloss finish the coarse texture will look a million dollars.
