Wood Appearance
Heartwood varies from fawn colour to reddish-brown. Sapwood is not well defined. There is lustre
and texture is medium to fine. The grain is straight and often interlocked. The bole is cylindrical, 18-
20m in length, 50-90(-120) cm in diameter.
Physical and Mechanical Properties
Very hard, strong dense and highly durable wood. Weighs approximately 900 kg/m3 (56/ft3) seasoned.
Medium shrinkage, very stable once dry. Very good mechanical properties, good elasticity and
impact resistance:
• Kiln dried density (12%) - 950kg/m3
• Bending strength (at 12%) - 168 N/mm2
• Modulus of elasticity (at 12%) - 18800 N/mm2
• Crushing strength (at 12%) - 86 N/mm2
Natural Durability
Highly durable. Resistant to fungal attack even under unfavorable conditions of use. Good resistance
to termite attack
Timber Processing
Drying - Moderate rate recommended since risk of distortion is high.
Working - Power is required in sawing and machining. Blunting effect on saw is moderate. Prone to
chipped grain when grain is highly interlocked. Finishes smoothly even on the end-grain when grain
is straight.
Assembly - Glues well, nails and screws hold well.
Finishing - Varnishes and polishes without trouble.
Uses
Suitable for general house construction, panelling and flooring. Its attractive appearance makes it
suitable for furniture and decorative purposes. It can also be used for wheelwright work, counters
and work bench tops.
Supplies
Species abundant in Guyana. Adequate supplies to meet any regular demand.
