Jarrah Tree

Why Jarrah Timber is Popular in CFM Carpentry

Jarrah (botanical name; Eucalyptus Marginata) is a distinct, Australian hardwood renown for its durability, versatility and strength. It’s ideal for different design and structural implementations which make it popular in CFM carpentry. What’s more interesting is the fact that the timber comes in different colors ranging from deep red to a blonde hue.


It’s origin

Jarrah trees dot the iron and aluminum rich plains of the south-western areas of Western Australia. This area spans from Eastern Perth all the way down to Albany. It takes long to mature and is known to have deep roots. On average, the jarrah tree can grow to a height of up to 40 meters and a width of 2 meters. Unlike many hardwoods, the jarrah tree does not germinate from seed but instead re-propagates from lignotubers.


Why jarrah is an excellent timber

The texture of the timber is moderately coarse or even (depending on the species) making it an appealing architectural and design material. On occasion, there may be some incidence of a wavy, interlocking grain. It’s resistant to rot, adverse weather elements, fires and even marine borers. These properties make it ideal for a range of outdoor uses including railway sleeper construction, wharf and bridge construction and making of poles and piles among other things. It can also be used for general house flooring, framing, joinery, fencing and lining.

The easy of use of jarrah in CFM carpentry depends on whether the timber is seasoned or not. It’s relatively easy to work on when it is green. In addition to this, it can be machined or turned easily. However, when it’s in a planer the blade should be set at an angle of 15 degrees for the best surface- quality. Steam bending and gluing is also possible with this timber. For a finishing touch jarrah can be painted, varnished or even polished. You will commonly find jarrah in sawn or veneer form.
