What is Yellow Balau?

Yellow Balau, is a wood obtained from trees of the Shorea species of Southeast Asia. It is used for decking, structural timber, flooring, shipbuilding, barrels and many other applications. It is also known as Bangkirai.


Durability is a known benefit of this species. It has a strength equal to 1,600Ib/ft2 to the Janka strength scale. For those who are not familiar with this term–this means Balau hardwood is stronger than many other wood types. It is also extremely resistant to marine borers making it ideal for use in marine applications.


For this reason, it is mainly used in outdoor projects: while boat decks and shipbuilding are among its many uses, Balau is mostly used as a decking material in the UK. This product also features in public projects. For example, Boardwalk in Youghal, in County Cork, Ireland, is a project that has used Balau Hardwood. Similarly, Titanic Belfast tourist attraction also makes use of it.

It is a beautiful hardwood. As its last layer has an attractive yellow colour, it’s the preference of people wanting a warm yellow look on their floors & decks. However, as this wood tends to shrink, it is not a suitable species for most internal joinery applications.

Texture & Colour

It has an interlocking grain, even texture and yellowish colour. So, if you are looking for a warm colour in your decking project and need a durable product, Balau is something you need to consider.
