One of the most commonly used decking timbers, Merbau / Kwila (Find out what the difference is between Merbau and Kwila on our Timber-Tips page!) is a tough, durable and beautiful timber. It is prefect for decking. You should always remember that there are different levels of quality available, and while it is quite common to see Merbau being sold at budget prices, care should be taken to ensure the timber you are buying is of an appropriate quality. At Tradeware, we source only the best quality Merbau/Kwila available.
