Please find below our description of this specie in an attempt to give as much detail of this timber to help both the trade person and ley person make an informed choice. We believe our stocks are among the best available in the UK.

We recommend customers order +10% over and above requirements to allow for waste on your project. We cannot supply every length defect free.

Certification
SLVK certified. The SVLK assurance scheme is a mandatory system that requires all timber from state-owned and private forests in Indonesia to obtain verification of legality – as a guarantee that the timber originates from legal, sustainably-managed sources.

Grading
Unlike other species, Yellow Balau has no specific ‘grading rule book’ and generally is sourced on the trust basis that certain mills produce a superior production selecting out lower grade boards for other uses. We use our considerable experience to source from the best shippers and to the specification that we believe is the best in the UK.

Appearance
Generally a Golden brown colour with occasional lighter and darker colour boards. Boards are hardwearing and dense. Boards are packed with ‘cross stickers’ to aid in drying and make the bundles safe to handle these can sometimes leave marks across the boards which are not regarded as a defect. Boards are generally supplied to full lengths or a fraction over the length with waxed ends to assist in reduction in end splitting. Occasional boards will have slight areas of missed machining and possible the odd ‘pin worm’ holes these are again allowed within this specie and should be accounted for in the recommended waste to be factored in.

Lengths
The lengths we have available are listed in the drop-down box to the right and can be selected and ordered online. Boards are generally straight but more likely to be Bent in some of the longer boards. To overcome the odd bent board we recommend the purchase or hire of our ‘hardwood wrench’ when fitting long lengths.

Machine tolerances
Yellow Balau is machined at source in Indonesia and due to the drying & shipping process, the boards can vary in width when they reach their final destination. It is fairly common to find boards within a batch to vary 5% in width from board to board and more rarely up to 7.5% tolerance can be expected.

Moisture Content
Yellow Balau is generally supplied as ‘Air Dried’ (approx. 18%) but in many cases and to speed the drying phase up we source Kiln Dried Stock. This Kiln Drying process is not like the typical sub 10% that is required for timber generally used internally but rather is kiln dried to 10-18%. This is just enough to get rid of the free water without banishing the bound water and hardening the cell walls of the wood and therefore making it more brittle and resistant to change.

Specie
Sourced from Indonesia, Yellow Balau is a very hardwearing durable decking which is classed at the high D50 strength rating. Density is high with an average weight of 980 kilos per m3. Decay resistance is rated as high and longevity is rated as 25 years +.

Fitting
Generally installed with stainless steel brads and a nail gun. Regular fixing points are advised at 450mm centres and near the ends of each piece.
