General Description: The heartwood colour is medium to dark red brown with conspicuous white dammar or resin streaks. Grain is interlocked; texture rather coarse. Brittleheart can be present. Weight from 580-770 kg/m³ (36-48 lb/ft³) average 670 kg/m³ (42 lb/ft³); specific gravity .67.
The wood has medium bending and crushing strengths, but the stiffness factor is low and also low resistance to shock loads. Severe buckling occurs in steam bending and distortion during drying. The steam bending classification is poor.
Slower drying than light meranti, with tendency to distort and risk of splitting and checking in thicker material. There is small movement in service.
Sapwood liable to attack by powder post beetle. All species are moderately durable to durable, and from moderately resistant to extremely resistant to preservative treatment.
