In this article we will compare the appearance, installation, maintenance and cost of these two common decking timber types, so you’ll have all the information you need to get started.

Treated Pine Decking

Treated pine decking is quite new in terms of decking timber. It has exploded in popularity and is one of the most plentiful options on the market. This is due to it being a relatively inexpensive option that can produce a great looking deck.

Treated pine decking is super easy to work with. It is very lightweight and completely versatile which makes it a great choice for those looking for a DIY job as well as professional installation.

Treated pine decking is on the cheaper end of the spectrum compared to some of the other decking timber types. This makes it the best choice for those looking to build larger decks or have less to spend on a tight budget.

Merbau Decking Timber

Merbau decking timber was once the reigning champion timber of choice for most decks in Australia. Although it is no longer on top it is still a very popular choice.

Merbau decking timber has a very high durability rating meaning you can throw anything at it and it’ll keep performing. It also benefits from being rot and insect resistant. Try and look out for sustainably harvested merbau decking timber as a lot of Australia’s supply comes from southeast Asian rainforests. It can cost a little more than usual but is a positive for the environment.
