What Makes Iroko Unique

Iroko is often referred to as “African Teak” due to its similar appearance and exceptional natural durability, particularly in outdoor applications. While not botanically related to teak, it shares many of its most desirable characteristics, including resistance to rot, insects, and moisture. Its warm golden-brown color develops a rich patina over time, echoing the timeless appeal of premium tropical hardwoods.


Why Choose Iroko

  • Exceptional Natural Durability: Highly resistant to rot, decay, and insect attack

  • Stable and Reliable: Maintains excellent dimensional stability when properly seasoned

  • Attractive Appearance: Develops a rich, deep patina with age and sunlight

  • Good Workability: Machines and finishes well with proper tooling

  • Excellent Value: Teak-like performance at a more accessible price


Why You Might Not Choose Iroko

  • High Silica Content: Rapidly dulls cutting edges

  • Interlocked Grain: Can cause tearout if tools are not sharp

  • Color Variation: Natural variation and aging may result in uneven tones

  • Health Sensitivity: Dust may cause irritation; proper PPE is recommended


Climate Performance & Acclimation

Iroko performs exceptionally well in humid and outdoor environments. For interior projects, proper acclimation is essential to ensure stability and minimize movement.


Ideal for Outdoor & Marine Projects

Its natural resistance to moisture and decay makes Iroko a trusted choice for patios, marine components, and exterior architectural elements.


Color and Grain Stability

Exposure to sunlight deepens Iroko’s natural color into a rich brown patina over time. Proper finishing helps protect the surface while enhancing its natural luster.
