Hardwood deckboards are approximately three times the price of softwood deckboards. They are more durable and ideally they need oiling each year to keep colour and encourage water run off. In 2014 we added a low-slip hardwood deckboards option and then in early 2015 we also added smooth Balau hardwood deckboards as a standard stock product.
Balau, also known as Bangkirai, is a durable hardwood and popular for machining decking boards. Our Balau stocks are normally TFT (Tropical Forest Trust) certified, the boards are of Malaysian origin and are a yellowish brown colour with a moderately fine grain. Bangkirai, or Balau, is the collective commercial name which covers approximately 40 similar hardwood species.
These hardwood deckboards boards are normally supplied to us in lengths of 3.3 – 3.9 metre lengths. Balau deckboards are air dried and untreated so there will be colour variations from one decking board to the next, this is particularly noticeable when the decking is first laid. Oiling will help to even out any colour differences which will eventually disappear if the boards are allowed to go grey.
Hardwood decking boards are naturally rot and insect resistant, during air drying the boards are spaced with narrow hardwood strips which might initially show as lighter strips along the deckboards length. The boards are dense and hard timber, but they do sometimes have some tiny pinhole marks in the timber face – this pinhole feature is permissible within the products grade. Newer, fresh cut boards might also leach lightly for the first few weeks so care must be taken near light coloured materials, you could also use Osmo sealing wax for cut board ends.
