Iroko is a heavy wood with light yellowish sapwood, distinctly different from the yellow-brown heartwood that after the cut acquires a golden brown color.

Medium or coarse texture with often crossed fibers.

Technological properties

The Iroko is characterized by a medium hard wood, which is worked without difficulty. Withdrawals and deformations are medium, even after curing.

In the wood there are limestone secretions, even of considerable size, which can damage the tools.

It is very resistant to bending and yielding. Very durable with mushrooms and also resistant to attack by termites.


It lends itself well because of the good mechanical properties and natural durability to uses in buildings also outside such as naval works, roofs for exterior of boats, carpentry, carpentry work, windows, floors, benches and outdoor furniture, port quays, cornices and profiles.

Typical defects

Limestone concentrations in the trunk; uneven grain.
