Yellow Balau Boards
Yellow Balau boards are a dense tropical hardwood, also sold as Bangkirai, for hardwood decks, facades, benches and heavy outdoor work. Choose a 190×27 mm board for decks and facades, or a heavier 145×45 mm board where the timber has to take real wear. Every board is Durability Class 1, stocked in our warehouse and delivered across Ireland.

Yellow Balau Boards for Sale in Ireland
If you want a hardwood deck or facade you’ll still be enjoying in twenty five years, Yellow Balau is hard to beat. It is one of the densest tropical hardwoods on the market, around 930 kg/m³ and more than twice the density of cedar, and that density is what gives it Durability Class 1, a service life of 20 to 25 years and natural resistance to rot, insects and fungal decay.
The boards arrive a warm golden yellow brown with a fine, even grain that takes a finish beautifully. Yellow Balau has been used for decades in marine work, busy commercial decks and exposed architecture.
Yellow Balau board sizes
We stock two sections, so pick by how hard the board has to work. The 190×27 mm board is a wide hardwood board for decks and facades, with a broad face that covers ground quickly, and a longer length means fewer joints on a long run. The 145×45 mm board is the heavy section for benches, heavy rails and surfaces that take the most wear.
How much do Yellow Balau boards cost?
Yellow Balau costs more than softwood because it is a dense, Class 1 hardwood, and the 45 mm section holds more timber than the 27 mm board. The fairest way to compare is by cost per m² of deck or facade, or per metre of rail, rather than per board, because the lengths differ. Enter your area in the calculator on the product page and it works out how many you need; the cart adds the fixings and extras.
Yellow Balau vs other timber boards
Planed oak boards are the other hardwood in the range, Durability Class 2, and suit bench tops and trims where oak’s grain is wanted. For a lighter softwood board, see Ecowood boards or Douglas Fir boards. For a grooved deck in the same species, see Yellow Balau decking, and for the frame underneath, hardwood joists.
Fixing Yellow Balau boards
Dense hardwood needs a little more care to fix than softwood. Pre drill at every fixing point, because at this density a forced fixing splits the board. Use stainless steel A2 or A4 screws or ring shank nails, never galvanised or mild steel, because the timber’s natural tannins react and stain the surface. See our timber screws.
Looking after Yellow Balau
Yellow Balau doesn’t need treating to last, but left bare it weathers to a silver patina. Most customers want to keep the warm golden tone, so they apply a hardwood oil made for dense tropical timbers within the first few months, refresh it yearly for the first couple of years and then every two or three years. Deks Olje saturating oil is in our exterior wood oils range.

Is Yellow Balau slippery when wet?
Its dense surface naturally sheds water and resists the slipperiness that affects cheaper hardwoods after a few wet winters.
How do I oil Yellow Balau?
Use a hardwood oil made for dense tropical timbers, such as Deks Olje D1. Apply it within the first few months, refresh yearly for the first couple of years and then every two or three years, and avoid film forming paint, varnish or stain.
