Decking Timber – Deckboards

There are three broad groups of decking timber:

  1. Hardwood decking (sometimes called hardwood timber),
  2. Treated pine decking (sometimes called softwood decking),
  3. Composite decking (sometimes called plastic decking).

Hardwood Decking – Deckboards

For decks Gold Coast and decks Brisbane, the most commonly used decking material is hardwood decking.

Popular species of hardwood decking include merbau decking (also known as kwila decking), spotted gum decking and blackbutt decking.

The merbau decking is sourced from South East Asia. It’s standard size is 90x19mm. This means that it is 90mm wide and 19mm thick. Other sizes also available include 140x19mm, 140x25mm, 140x35mm.

The spotted gum decking and blackbutt decking is sourced from Queensland. It’s standard size is 86x19mm. Other sizes also available are 135x19mm.

The above species of hardwood decking all have a class durability rating of 1. This means that their expected life is around 25-30 years.

Suggestion – When choosing a hardwood decking material, remember to see whether your proposed hardwood decking species can also be used for your balustrade or handrail, timber stairs, privacy screens, planter boxes and decking oil. Since not all hardwood decking species are readily available for all applications, all year round.
