DESCRIPTION GÉNÉRALE DU BOIS
Odeur
Light and pleasant odor.
Teinte
The heartwood is yellowish white to pale brown or pinkish brown, it is not clearly demarcated.
Index de Teinte (1 = Noir, 7 = Jaune clair)
6
Grain
Straight or slightly interlocked, sometimes with an influence on further processing operations.
Texture
Texture is mostly fine to medium.
Luster
The wood surface is moderate in luster.
Durabilité naturelle
Slightly durable to decay. This species needs preservative treatment for uses with risks of occasional re-humidification. It is not suited for uses with risks of permanent or long-lasting humidification. Heartwood is sensible to termites and Lyctus attack
Index de durabilité naturelle (1 = Très élevée, 7 = Très faible)
6
Tensions internes de croissance
No residual growth stresses are found.
Résistance à l'imprégnation
Easy to treat with a full penetration of the preservative products using vacuum-pressure method.
