Characteristics: The sapwood is lighter in colour than the heartwood, which varies from yellow to a reddish-brown colour. There is a pronounced difference in colour between early-wood and late-wood zones which give the wood a very distinctive figure on plain-sawn surfaces. Some resin ducts and pockets are present. The average weight of dried timber is 530 Kg / m3. The wood is moderately durable.
Working Qualities: Works readily and fairly easily, but with a slight dulling effect on blades. With care, a good finish is obtainable, and the wood can be nailed, screwed, glued, stained and polished satisfactorily. Resin canals tend to bleed at times.
Uses: Heavy construction, piling, masts and spars, dock and harbour work, barges, joinery, flooring, windows and doors, ship building, roof trusses, furniture, and for veneer and plywood.
