Important Tips for Choosing the Right Timber for Your Home's Decking

When you're ready to have a deck installed outside your home, you want to give some thought as to the type of timber you choose. Some species will be more attractive than others, so they may require less painting and staining, and some timber types are more durable, so you may need to repair the surface less often over the years. Note a few tips on choosing the right timber for your home's decking, so you know your deck will be as durable as expected and will be an investment you enjoy for years to come.

Know the classifications

Timber is classified according to density and durability; this classification is often a numbering or lettering system, so Class 1 or Class A timber may be the densest and durable, while Class 4 or Class D is softer and less durable. While you may want to save money and choose a lower class timber for the deck surface, note that the footings, posts, and other pieces that give the deck structural support should always be a higher class. This will ensure they're very dense and durable and work to hold up the deck properly.

Also, if you want to construct the deck yourself, check on the tools needed for cutting and fabricating the higher classes of timber. Some species may be so dense and tough that you may not be able to cut through them with standard power tools, so you may need a lower class of timber that is more easily fabricated.

Treated timber

Timber that is used for any home project is always treated, but there are different types of treatment that might be applied to the wood. Outdoor timber should be treated to resist termites, moisture, and fire hazards; never use interior flooring timber or any boards that have not been treated for these outdoor risks for your home's decking.


Jarrah is somewhat expensive but is very dense and fire-resistant, so it's a good choice if your home is at risk of brushfires. The species also has a very rich red tone, so you may not need to paint or stain it once the deck is installed.

Merbau is very rot resistant and also resistant to termites; this is a good species for areas with higher humidity levels, as the wood is less likely to absorb that moisture and then rot or chip. Spotted gum is also good for areas with high humidity levels, as it doesn't expand naturally, as do other types of species when they're exposed to moisture.
