Why Merbau (Kwila) Timber is a Top Choice for Decking

March 17, 2025

When planning an outdoor space, choosing the right decking material is one of your most important decisions. It affects how your deck looks and how it performs over time. In Australia, merbau timber continues to stand out as one of the most trusted options for building decks that last.

Also known as kwila timber, this hardwood is valued for its strength, beauty and reliability in outdoor conditions. Here at Sunstate Timbers, we stock the finest quality merbau decking timber to help homeowners across Brisbane create spaces that are both functional and timeless! Let’s understand why, for over 35 years, merbau has been a popular choice for Brisbane homeowners.

Built to Handle the Outdoors

Merbau timber is a dense hardwood with natural resistance to moisture, decay and termites. This makes it incredibly well suited to Australian weather conditions, from the humid tropics to dry inland areas.

It holds its form well, even when exposed to full sun or heavy rainfall. This timber offers peace of mind and a long-lasting solution for anyone building a merbau deck around a pool, garden or entertaining area.

Natural Beauty That Lasts

One of the standout features of kwila timber is its warm, reddish-brown colour. The grain is rich and textured, creating an inviting look that works beautifully with most outdoor design styles.

Over time, the timber develops a silver tone if left untreated, but many homeowners choose to oil their merbau deck to maintain the original colour. Either way, it adds immense character to outdoor areas and blends seamlessly with natural surroundings.

Easy to Maintain Over Time

Merbau decking timber is tough and low maintenance when cared for correctly. A quality sealing oil and occasional cleaning will keep it in excellent condition for years.

Compared to softer timbers, merbau does not require frequent refinishing. This makes it ideal for busy households or holiday homes where low maintenance is a priority. With the right preparation and sealing, your deck stays strong, safe and looking great with minimal effort.

Perfect for the Australian Outdoors

From pool surrounds to pergolas, kwila timber has the strength and slip resistance needed for all kinds of outdoor spaces. It can handle foot traffic, weather changes and furniture without warping or splintering.

Its natural density also makes it a good choice for raised platforms or structural framing where additional support is needed. Whether you are building a small entertaining area or a large multi-level deck, merbau timber offers both versatility and value.
