Grain Pattern
Interlocked with a coarse texture; presents a distinct mottled or 'roe' figure when quarter-sawn. Grain is slightly irregular with prominent large pores.

Durability & Decay Resistance
Very Durable; highly resistant to rot and insect attack (termites). Often used as a substitute for Teak in outdoor applications.
Value & Sustainability
- Estimated Market Value
- $14.00 - $20.00 per board foot depending on figure and width.
- Wood Age Estimate
- Freshly milled to recently seasoned (less than 1-2 years), evidenced by the lighter yellow-gold hues and lack of deep oxidation/patina typical of older Iroko.
- Sustainability Status
- Listed on the IUCN Red List as Near Threatened; not listed on CITES appendices but regulated by local harvest quotas.
Common Uses
Decking, boat building, outdoor furniture, cabinetry, flooring, and heavy construction.
Geographic Origin
Tropical Africa (West and East Africa)
Workability
Generally fair; interlocked grain can cause significant tearout during planing. Contains calcium carbonate deposits (stone) which can severely dull tool edges. Glues and finishes well.
Finish Recommendations
Responds well to most finishes; however, oil-based waxes or marine-grade varnishes are recommended to highlight the chatoyance and protect it in outdoor settings.
Notable Features
Faint scent when being worked; dust can be a potent sensitizer causing respiratory irritation or dermatitis. Known for its 'teak-like' properties but without the same level of natural oils.
