Yellow Balau (pronounced Bal-Ow) – Bangkirai – is a very durable hardwood and one of the most popular species in the UK for hardwood decking. It’s a hard, heavy and strong timber that is well suited to deck construction.
With a mixture of warm colours of golden browns, light browns and pale reddish-brown, Yellow Balau offers a unique colour range which will sit beautifully within a natural environment.
Size: 21 x 145mm – various lengths available.
Grade: Standard & Better.
Profile: Yellow Balau deck boards have bevelled edges.
Surface texture: Smooth.
Produced predominantly from the heartwood, Yellow Balau can vary in colour from reddish-brown to a more olive or darker blackish brown. It has an interlocking grain, fine uniform texture and a surface that is almost entirely free of knots and other natural defects. Occasional pinhole and hit and miss is acceptable within the grading rules of Yellow Balau decking.
Yellow Balau has a natural resistance to moisture, decay and insect damage. With a proven life expectancy of 50+ years (when correctly maintained), it has a Durability Class 2 (BS EN 350-2) (durable) rating and is known to be one of the toughest and most durable hardwoods on earth.
Wood is a hygroscopic organic material that takes up and releases moisture according to the temperature and the relative humidity of the ambient air. As wood releases moisture it will shrink (usually during summer) and as it absorbs moisture (in the winter months) it will expand. The rate of expansion and contraction will vary according to the grain orientation of the wood. This means that some pieces will expand or contract more than others, so there may be minor variances in the width of the boards (known as tangential shrinkage). Shrinkage in the thickness (radial) is minimal and length (longitudinal) virtually non-existent.
Density & Hardness:
Yellow Balau is the hardest of all commercially available hardwood species; in fact, it’s one of the hardest woods on Earth. It has a Janka scale rating of 3510 lb/in2 (3 times harder than Oak) and weighs in at 960 – 12000 kg/m3 when dry. As a result, it’s highly resistant to impact and abrasion.
Yellow Balau decking is ‘Standard & Better’ grade which has excellent characteristics. Its appearance is almost entirely free of knots.
