- Iroko cladding has a distinct yellow colour, but on exposure to light it quickly becomes golden-brown.
- The sapwood is narrow, being about 50mm to 75mm wide, and clearly defined.
- The grain is usually interlocked and the texture is rather coarse but even, and the wood weighs on average 660 kg/m³ when dried.
- Large, hard deposits of calcium carbonate called ‘stone’ deposits, are sometimes present in cavities, probably as a result of injury to the tree. They are often enclosed by the wood and not visible until the time of sawing, though the wood around them may be darker in colour, thus giving an indication of their presence.
- Iroko has excellent strength properties, compared well with teak, though weaker in bending and in compression along the grain.
