Other Uses

The heartwood is reddish brown, often with irregular brown streaks; it is usually distinctly demarcated from the wide band of pale pinkish grey sapwood. The grain is often wavy and irregular, texture moderately coarse to fine. The wood is heavy; hard; moderately durable but liable to termite and Lyctus attacks. The working properties are variable, depending on the amount of irregular grain in the material. The wood saws moderately well, and planing may result in woolly surfaces due to tension wood. Pre-boring is necessary for nailing and screwing. The wood is used for indoor as well as outdoor construction. It is also suitable for flooring, mine props, shipbuilding, vehicle bodies, furniture, agricultural implements, interior trim, joinery, railway sleepers, poles and piles, carving, toys and novelties, turnery and pattern making[].
