Native to Malaysia, Indonesia and the Philippines, Bangkirai is a dense hardwood used mainly for heavy construction.
The heartwood of Bangkirai is yellow to brown, which is distinct from the paler sapwood. Its moderately fine and even texture presents and interlocked grain, which produces a stripe figure on the radial surface. Bangkirai is also susceptible to pinhole borer damage.
In relation to its density, Bangkirai is relatively easy to work. It does not contain sillica, however resin pockets may be present, meaning resin can build up on cutting equipment. Pre-drilling is advisable when nailing. Bangkirai can be painted, stained and polished but is not suitable for steam bending.
