In this case, the Niangon name only includes Heritiera (=Tarrietia) utilis timber from the coastal countries of Upper Guinea. However, the more Southern kind (Heritiera densiflora) also gets marketed as Niangon.


Botanical name: Heritiera utilis
Overall character: This large-pored wood optically resembles mahagony, but doesn’t have the same even structure.
Color and structure: The splint is light grey and about 5 centimetres wide. The heartwood contrasts the splint, it is pink when damp and light to dark auburn once it dries. It has a glossy matte finish.
Characteristics/features: Moderately heavy wood with strength properties similar to the sawn timber of the native oak, but with slightly higher scores than Sipo. Damp as well as dry Niangon is easy to saw, if clogging and burning are avoided by using a saw blade with an appropriate tooth shape.
Areas of use: Solid wood: Niangon, especially in France, is one of the most commonly used exterior timbers, where it is mainly used as window construction frame timber. It is also used for façade elements, doors and gates, profiled boards of wall coverings, and for roof underlayments of wooden houses.
