PRODUCT DESCRIPTION

There’s a reason merbau has been the go-to hardwood for Australian decks for decades — it simply performs where other timbers quit. Our Merbau Decking in 140x19mm is the full-width, traditional board profile that suits both residential patios and larger commercial outdoor areas, delivering that unmistakably warm reddish-brown tone that gets better with age.

It’s naturally resistant to termites and rot, which takes a major headache off the table for anyone building in coastal or humid environments.

The 140mm width gives you that classic, generous board face that reduces the number of joins across your deck, keeping the visual lines clean and the installation time down. At 19mm thick, these boards have solid substance underfoot — no flex, no bounce, no compromise on structural feel.

Ideal for decks, pergolas, alfresco areas, pool surrounds, garden paths, and screen fencing. If you’re planning something that’ll still be standing — and looking good — in 25 years, this is the board to build with.

Q: Is merbau decking suitable for pool surrounds in Australia?
A: Yes — merbau is one of the most popular choices for pool surrounds across Australia. Its durability rating and natural resistance to moisture and insects make it well-suited for wet areas.
Q: How long does merbau decking last outdoors in Australian conditions?
A: When properly maintained with regular oiling and appropriate fixings, merbau decking can last 25 years or more. Its durability rating means it's engineered by nature for above-ground outdoor exposure, including in harsh Australian climates.
Q: What spacing between boards is recommended for merbau decking?
A: A 3–5mm gap between boards is standard, allowing for water drainage and minor timber movement. Merbau is a relatively stable hardwood due to its interlocked grain, but all timber expands slightly in high humidity — so don't butt the boards tight.
