Hardwood balau deckboards are approximately three times the price of softwood deckboards. They are more durable tahn softwood and ideally they should be oiled every year to maintain the boards colour.
Balau deckboards and other types of hardwood decking
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. These boards are of Malaysian origin and are a yellowish brown colour with a moderately fine grain.
Length availability is normally around 3.6 metres, larger areas can be divided into smaller sections by using smooth Balau deckboards. This means the end alignment of the profiled boards is not so demanding. Smooth boards can also be useful as a visual indicator of deck level changes.
Appearance of the hardwood deck boards
Because Balau deckboards are air dried and untreated there will inevitably be some colour variations between boards. Oiling will help to even out any colour differences which will eventually disappear if the boards are allowed to go grey. It is normally recommended to leave the boards for 3-6 months to allow the natural tannins to leach out of the timber.
Hardwood decking boards are rot and insect resistant. During the air drying process the boards are spaced with narrow hardwood strips which might show as lighter strips along the deckboards length. The boards 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. Therefore care must be taken near light coloured materials e.g. limestone chippings. To help reduce the leaching from board ends you can use Osmo wax to seal the board ends. Oiling of the deckboards will help water to bead on the board surface. Brushing the deck down will also help to slow down algae growth
We also keep a range of stainless steel fixings for use with these decking boards. Our images of hardwood decks have been provided by Legendary Landscapes and Clipper Garden Services.
