Structural Hardwood

The extreme external conditions found in Australia often require the natural durability and strength of Structural Hardwood. Produced from predominantly Queensland grown Eucalypt species, some of the hardest and most durable timbers in the world. It is naturally resistant to attacks by insects and has a high resistance to decay and fungal activity.

If the correct type of timber is not used in certain outdoor applications, it sometimes fails to perform to user expectations. In most cases this is not the fault of the material but rather as a result of a lack of understanding of the various species of timber, their suitability and their installation and maintenance. This is where the expert team at Garde Timber can help. We’ll help you select the right timber species and specification for your unique job.
