Benefits of 140mm Merbau

✔ Better airflow under your deck reduces the risk of bowing & moisture damage
✔ Add unique flair to your deck with a wider-style deck board
✔ Enjoy the durable & long-lasting benefits of hardwood merbau decking
✔ Kiln-dried decking boards allow you to enjoy a secure, safe deck for years

When using wider deck boards like these, we don’t recommend installing them near water sources like pools or lakes. Due to their wide and thin profile, they are more likely to cup or warp from water damage.
