Common Name(s): Balau

Scientific Name: Shorea spp.

Distribution: Southeast Asia

Tree Size: 150-200 ft (45-60 m) tall, 3-6 ft (1-2 m) trunk diameter

Average Dried Weight: 53 lbs/ft3 (850 kg/m3)

Specific Gravity (Basic, 12% MC): .69, .85

Janka Hardness: 1,600 lbf (7,120 N)

Modulus of Rupture: 17,730 lbf/in2 (122.3 MPa)

Elastic Modulus: 2,457,000 lbf/in2 (16.95 GPa)

Crushing Strength: 10,280 lbf/in2 (70.9 MPa)

Shrinkage: Radial: 5.5%, Tangential: 10.1%, Volumetric: 15.7%, T/R Ratio: 1.8

Color/Appearance: Color can be highly variable depending upon the species: ranging from a pale straw color, to a darker reddish brown.

Grain/Texture: Has a coarse texture with medium to large pores. Grain is sometimes interlocked.

Rot Resistance: Highly variable among species; should be considered as non-durable in regard to decay resistance, and is also susceptible to insect attack.

Workability: Typically hard to work, due to its high density. Some species may have a slight blunting effect on tools due to small levels of silica present in the wood. Glues, stains, and finishes well.

Odor: No characteristic odor.

Allergies/Toxicity: Although severe reactions are quite uncommon, Balau in the Shorea genus has been reported to cause eye, throat, and skin irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Balau is widely harvested and widely available worldwide. It should be moderately priced despite the fact that it is imported.

Sustainability: Balau is not listed in the CITES Appendices, but many species in the Shorea genus are on the IUCN Red List. The majority of Shorea species are listed as being critically endangered due to a population reduction of over 80% in the past three generations, caused by a decline in its natural range, and exploitation.

Common Uses: Plywood,veneer, general construction, flooring, as well as a number of other general utility purposes.

Comments: Sometimes referred to as “Lauan,” wood in the Shorea genus is very commonly used in southeast Asia, and there is an abundance of variety between the difference species: each with different working properties, appearances, and mechanical strength values.

The five main groupings for Meranti (Lauan) are: Light Red Meranti, Dark Red Meranti, White Meranti, Yellow Meranti, and Balau. The strength and mechanical values listed at the top of this page represent the average of a handful of species within the corresponding group.

Also called Philippine Mahogany, Meranti bears no relation to  what is considered to be “true” mahogany in the Swietenia and Khaya genera.

    can I coat balau wood with poly

    • Cyrus

      to preserve the natural wood grains, I recommend using linseed oil, teak oil or mineral oil instead because this is a very tough and durable wood and unless you are dealing with very harsh conditions, there is no need to take away some of its natural beauties by using polyurethane, use oils instead, otherwise you can use poly on anything

    does the bacteria and do the insects this wood is prized by live in north America? It seems to me the climate change could preclude your assertions? can anyone in the US confirm having a rotten or insect eaten red balau deck?

  • I wouldn’t coat it with anything. Coatings can peel and flake, oil can’t. http://blog.thewoodjoint.co.za

    I am haing some cracking in some doors i made with a yellow balau core and a 1/8″ thick face veneer of yellow balau. The faces are cracking lengthwise. Why would this happen to kiln dried wood

    • Hi JJ. Balau is a very oily and resinous wood so even though it has been kiln dried it still contains a fair amount of resins and oils. As this dries out over time it can cause cracking especially in such a thin veneer. Possibly also because the veneer is stuck to the carcass of the door it is prohibited from expanding and contracting. I’ve noticed a fair amount of expansion and contraction in balau. I made T & G floor boards which didn’t work well as they contracted quite a lot after we installed them. Balau doesn’t like to be glued. http://blog.thewoodjoint.co.za

    I’m looking at a patio set described as a Jakarta Wooden Patio Set

    Is Jakarta a region where this wood is grown or is it the actual wood?

      Pretty sure that’s just where the wood was sourced. “Shorea” is a genus of trees that contains many species listed by the IUCN as being critically endangered, so hopefully when they claim it is “sustainable” that claim is genuine.

    what is the other alternative for red balau? Can i use red meranti?
