The fibrous bark is used for making rope and for tying purposes[
The bark is cut into small pieces and boiled to make a dye that is used to colour and strengthen cloth, fish nets, ropes etc[
]. The bark contains tannins and therefore acts in part as a preservative[
The heartwood is a dull purplish brown, or reddish brown, fading on exposure to a light brown; it is not sharply distinguished from the somewhat paler sapwood. The texture is fine and smooth; the grain straight or slightly crossed; there are distinct ripple marks on all longitudinal sections in most specimens. The wood is moderately hard and rather tough; moderately heavy to heavy; not very durable when exposed to the elements, but somewhat resistant to beetles. It seasons well and is easy to work. From the colour, texture, and presence of ripple marks on the wood, it is easily mistaken for lanutan (Bombycidendron spp). It is used for posts (placed above stumps), beams, joists, rafters, flooring, sheathing, ceilings, furniture, cabinetwork, household implements, combs. If impregnated with preservative, it would make good ties and paving blocks[
