General Information

Koompassia malaccensis is a deciduous tree; it usually grows up to 45 metres tall, though can occasionally reach up to 60 metres. The straight, cylindrical bole can be free of branches for up to 25 metres, 60 - 149cm in diameter with steep, plank-like, thick buttresses up to 6 metres high[, ].
The tree is often harvested from the wild for its wood, which is a useful timber species for heavy construction and is currently gaining importance in trade because of the shortage of heavy hardwood timbers[].
The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2013)[].

Other Uses

The heartwood is pink when freshly sawn, turning to orange-red or yellow-brown upon exposure; it is clearly demarcated from the about 5cm wide band of white or pale yellow sapwood. The texture is coarse; the grain straight or interlocked; lustre is variable; there is no distinct odour or taste. The wood is heavy; moderately hard; elastic; somewhat durable, being resistant to fungi but susceptible to dry wood borers and termites. It seasons slowly, with a high risk of checking and distortion; once dry, though, it is stable in service. The wood has a fairly high blunting effect, stellite-tipped and tungsen carbide tools are recommended; the wood has concentric layers of phloem which may lead to sawing damages; nailing and screwing are good, but require pre-boring; gluing is correct. The wood is eminently suitable for heavy construction, and is also good for flooring, heavy carpentry, railway sleepers, dock blocks, turned goods, cooperage, fence posts, shingles, etc[, , , ].
The wood is used for fuel and produces a charcoal of high quality[, ].
