Okan’s heartwood is yellow to yellow-brown with a more or less light to dark green, olive green tint, which can sometimes give off a coppery glow under the influence of light red-brown. On the crosscut surface, the thick growth rings can be clearly identified by their dark coloured edges. The sapwood is light pink and 50-75 mm thick, and is clearly differentiated in colour from the heartwood. When damp, Okan has an unpleasant smell, but is without taste or smell when dry.


Okan is a Leguminosae (Mimoseae) family wood which originates from topical West Africa. The high density, durability and interlocked grain structure of Okan make it suitable for hydraulic constructions, like sheet pilings, stable bridges, etc.
