Merbau Decking Perth WA

Merbau is an imported hardwood from South East Asia, valued for its strength, stability and high durability. Merbau decking is recognised for its deep dark red to rich brown colour.

Its lasting aesthetic appeal is perfect for making a statement with variety of homes and outdoor decking styles. Austim Magna Merbau Decking has full FSC Certification, your guarantee of sustainable and ethically sourced timber.

Merbau Care & Maintenance

Deck maintenance is essential for timber and composite decking of all types. Merbau is the perfect decking choice if your deck is in a weather exposed area because of its high levels of durability. Merbau is an extremely stable timber option, so it has low tendency to twist and warp if it is installed correctly.

To keep your Merbau decking in top condition, you’ll need to control and minimise the release of tannins when it gets wet. This will not continue indefinitely and there are ways to limit it, such as staining and coating your decking.


The vast majority of our Merbau Decking is supplied pre-coated, however further applications of oil will be required once installed on-site. Intergrain Uni Oil Pre-Coat
