Buy Merbau Decking in Melbourne

Merbau has relatively low shrinkage and movement compared with many timbers, making it a practical hardwood option for exposed decking when correctly selected and installed. If you’re looking to buy Merbau decking in Melbourne, this page outlines what to check before you order.

What to check before you buy:

  1. Moisture content – Kiln‑dried Merbau with a moisture content around 12% at delivery, and air‑stabilised (unseasoned) stock can reach ~25% moisture and may shrink more after installation, so allow for acclimatisation on site.
  2. Grading – Choose boards graded for alignment and consistent colour, particularly for large deck areas. Natural colour variation is normal in Merbau; select a consistent grade and plan the layout to blend colour runs.
  3. Sourcing – Merbau is imported from South East Asia and the Pacific. Ask for FSC or equivalent chain-of-custody documentation.
  4. Stock depth – Merbau decking boards arrive in a range of lengths, and a deck run is built by joining several boards end to end to reach the total length needed. That is why you should buy from a supplier that has enough stock across 70x19mm, 90x19mm, and 140x19mm to avoid delays.

At Australian Treated Pine, we stock Merbau decking for Melbourne trades and residential customers, who can pick up or arrange delivery locally without waiting on a direct import order. Whether you’re comparing merbau decking Melbourne suppliers or ready to buy Merbau decking for your next outdoor area, our range supports both small residential jobs and larger commercial projects.

FEATURES & USES OF MERBAU TIMBER DECKING

Merbau is a versatile hardwood derived from South East Asia, Papua New Guinea, the Pacific Islands and northern Queensland. When freshly cut, its heartwood is yellow-orange brown, developing into a darker red-brown with age. On the contrary, its sapwood is pale, yellow, white or buff coloured. Typically variegated, Merbau’s grains are interlocked and wavy, with a coarse but even texture known for its attractiveness on back-sawn material.

It finishes nicely with paint, stain or polish and with its high degree of natural durability and strength, Merbau is used externally in engineering, construction and marine applications.
Merbau Decking Specifications

Density: ~860 kg/m³ once dry (dried to a stable moisture content). Generally, denser than softwoods and most other decking hardwoods.

Durability rating: Class 1 above ground, Class 3 in-ground. Rated for exposed decking, fascia and cladding.

Hardness: 8.6 kN on the Janka scale. Resists dents, scratches and heavy foot traffic.

Termite resistance: The natural resistance of Merbau to termites comes from its extractives.

Tannin bleed: New boards release tannins in the first few rain events, producing yellow-orange run-off.

Movement: It is a dimensionally stable hardwood, but still allows gaps for seasonal expansion and contraction.
