Other Uses

Most, if not all, members of this genus produce a heavy timber often used in construction[]. We do not have a specific description for the wood of this species, but a general description for the genus is as follows:-
The heartwood is a yellow-brown, becoming pinkish-brown upon exposure, fairly important waxen patches are more or less frequent; it is not clearly demarcated from the 3 - 5cm wide band of sapwood. The texture is coarse; the grain interlocked. The wood is moderately heavy to heavy; moderately hard to hard; elastic; somewhat durable, being moderately resistant to fungi but susceptible to dry wood borers and termites. It seasons fairly quickly with only a slight risk of checking and distortion; once dry it is poorly to moderately stable in service. The wood works well with ordinary tools, though there are possible difficulties if the waxen patches are numerous; the waxen patches remain visible after machining; a careful sanding must be done to obtain a good finish; nailing and screwing are good, but require pre-boring, there is a tendency to end checks when nailing; gluing is correct. The wood is used in construction, joinery, panelling, industrial flooring, stairs, heavy carpentry, furniture components etc[].
