Other Uses

The wood is heavy, hard and durable[, ]. It is used for piling (also in contact with ground and water), house construction, bridges, ships keels and ribs, heavy-duty flooring, turnery, cabinet work and railway sleepers, while less heavy timber is used for furniture, package and pallets etc[].
We have no more information on the wood of this species. However, the following is a general description of the wood for members of this genus;-
The heartwood is yellowish when fresh, turning light to deep red-brown upon exposure; it is generally not sharply demarcated from the lighter coloured sapwood. The texture is rather fine and even; the grain straight or shallowly interlocked; not lustrous; there is no distinctive taste or odour when dry. The heartwood, particularly that of the denser species, is rated as durable to very durable; with a good resistance to termites. It is generally reported to air season slowly, but with some warp and checking. Philippine species are reported to dry well with little degrade. The wood is said to be difficult to saw because of clogging due to gummy resins, otherwise it machines well to a smooth finish; turns well; there is some dulling of cutter blades due to silica in the wood. The wood is used for purposes such as turnery, heavy construction, mining timbers, railroad crossties, boat construction; it is also suggested for flooring, interior joinery, and cabinetwork[].
