Teak vs. Merbau: Which Is Better for Decking?

Teak and Merbau are two of the most requested species for outdoor decking, and buyers comparing them for the first time often assume the choice comes down to price alone. It doesn't. The right choice depends on the balance you need between durability, appearance, maintenance tolerance, and budget — and understanding a few practical differences up front saves both money and rework later.

Durability & Density Comparison

Both species rank among the more durable tropical hardwoods used in decking, but they get there differently. Merbau is denser and slightly harder underfoot, which suits high-traffic commercial decking. Teak's natural oil content gives it excellent dimensional stability and weather resistance even though its density is somewhat lower — which is part of why it has remained a benchmark species for marine and outdoor furniture for generations.

Cost Comparison

Teak generally commands a premium over Merbau, reflecting both slower growth cycles and stronger demand in the premium furniture and luxury decking markets. Merbau typically offers a lower cost per square meter while still delivering strong outdoor performance, which is why it remains the more common choice for large-scale commercial and resort decking projects where budget efficiency matters at volume.

Maintenance Differences

Merbau can release tannins during its first exposure to rain, which may temporarily stain adjacent light-colored surfaces such as pale stone or rendered walls — a detail worth planning around during installation rather than treating as a defect. Teak weathers to a silver-grey patina if left untreated, or can be maintained with periodic oiling to preserve its warm honey tone. Neither requires intensive upkeep; the difference is mostly about which look you're maintaining toward.

Best Use Cases for Each

Choose Teak when appearance and long-term refinement matter most — boutique hospitality decking, premium residential terraces, and areas where the timber is a visible design feature. Choose Merbau when you need dependable outdoor performance across a larger area at a more efficient cost — resort walkways, commercial boardwalks, and large-scale residential decking.

Recommendation Framework

If budget allows and the deck is a visual centerpiece, Teak is usually worth the premium. If you're specifying a larger area, working to a tighter budget, or prioritizing density and hardness for heavy foot traffic, Merbau is typically the more efficient choice — and both are available from us in the same certified, kiln-dried, export-ready supply chain.
