Merbau / Kwila for Decking

Merbau / Kwila Decking-TRADEWARE Building Supplies
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.

Merbau/Kwila does have an issue with tannin bleed. ...Like a cup of tea, when you mix Merbau/Kwila with water the timber releases a huge amount of tannin - So care must be taken around pools and ponds, light coloured driveways or paths, painted, paved or tiled areas, or anywhere where there is a risk of staining. Prior too being laid, the boards should first be cleansed of tannin, either by flushing with large volumes of water, or with a specially designed proprietary cleanser. They should then be sealed with either a water or oil-based product.

Our Merbau/Kwila decking is sold in either 90x19 or 140x19 with a 'ripple' back.

Pacific Jarrah Decking

Pacific Jarrah Timber Decking available from TRADEWARE Building Supplies, Chandler Brisbane
Like Merbau/Kwila, Pacific Jarrah it is an extremely tough and durable timber, but it has a distinct advantage in that it does not suffer from tannin bleed. It is an attractive decking timber with a unique pink/red colour and tight grain formation. It is without a doubt the most popular decking timber we sell. It is a very hard, durable timber.

Our Pacific Jarrah decking is sold in either 90x19 or 140x19 dressed on four sides.

Australian Hardwood Decking

We stock a range of Australian Hardwood species for decking including Spotted Gum, Iron Bark and Blackbutt. Australian Hardwoods make beautiful and unique decking timbers with strength and durability to match the Kwila and Pacific Jarrah.

Our Australian Hardwood decking is sold in either 86x19, 90x19, 140x25, 135x19 dressed on four sides. Sizes do depend on species and supply.
