At TopDecks, we build to AS/NZS building standards. All unseen framework is built with H3/H4 Treated Pine, unless in a fire-rated area at which point we use steel. Treated Pine has been used for building outdoor structures for years. Treated Pine framework is common for outdoor structures due to it being saturated with a preservative that protects it from termite infestation and decay caused by fungi.
There is a variety of different timbers that can be used for our decks, it all depends on the look you're after. Australia is blessed with some beautiful species of hard woods that look amazing and, most importantly, can handle the ever-changing Australian climate.
Below is a run-down of the timber we recommend. If you're unsure of what will look best in your outdoor space, give us a call for a FREE consultation and no-obligation quote.

JARRAH
Jarrah is sought after for its rich red and brown hues. Slightly less suitable for use above ground than other Australian timber decking, yet is still a popular choice due to its high quality finish.

MERBAU
Merbau is native to south-east Asia and is reddish brown in colour. Due to its affordability and attractiveness, its been the trend timber for the last
15 years.

SPOTTED GUM
Spotted Gum is an Australian hardwood. The colour ranges from light to dark brown and when finished gives a real rustic look. A high quality timber that can be used both at ground level and above ground.

TREATED PINE
A fast-growing softwood, Treated Pine is the most cost effective product on the market. Most of the pine used in production today comes from tree plantations rather than the virgin forests.
