Introduction
Iroko wood, also called African teak, is a strong and valuable type of wood that comes from tropical parts of Africa. It has a rich color, lasts a long time, and can handle tough weather.
Because of these qualities, it is often used in building and making furniture. In this article, you’ll learn all about iroko wood—what it is, what it’s used for, and why it’s a great choice for many different jobs.
What is Iroko Wood ?
Iroko wood comes from the Iroko tree, which is also known by its scientific name, Milicia excelsa. This tree grows quickly and can get very large. It is mainly found in West and Central Africa. The wood from the Iroko tree is very strong and long-lasting, which is why it is popular and widely used in the wood industry.
Physical Properties
Iroko wood boasts a variety of physical characteristics that make it an appealing material for many industries. Let’s break them down:
1. Color & Grain
Heartwood: Golden to medium brown, darkening over time.
Sapwood: Pale yellow, clearly distinguishable.
Grain: Interlocked or wavy, with a coarse texture.
2. Durability & Strength
Janka Hardness: 1,260 lbf (5,610 N) – comparable to oak.
Rot Resistance: Highly resistant to fungi, termites, and decay.
Stability: Low shrinkage rate, making it ideal for outdoor use.
3. Workability
Machining: Works well with both hand and power tools but may dull blades due to silica content.
Finishing: Takes stains, varnishes, and oils smoothly.
Gluing & Screwing: Holds fasteners well but pre-drilling is recommended.
Uses of Iroko Wood
Furniture Making
Iroko wood is often used to make strong and beautiful furniture. Its nice patterns and solid strength make it perfect for things like dining tables, chairs, wardrobes, and cabinets. The wood has a smooth surface, which makes it easy to shape and great for custom furniture.
Flooring and Decking
Iroko wood doesn’t get damaged easily by water or rot, so it’s a great choice for both indoor and outdoor floors. People use it in houses, offices, and shops. It’s also perfect for outdoor decks because it can handle rain, sun, and other weather conditions.
Boat Building
Iroko wood is great for making boats because it doesn’t get damaged by water and lasts a long time. It’s used in many parts of the boat, like the outside (hull) and the floor (deck). The natural oils in the wood help protect it from getting wet and spoiled.
Carpentry and Woodworking
Carpenters like using iroko wood to make things like doors, window frames, and wall panels. It’s easy to cut and shape, and it’s very strong, so it’s good for small and big wood projects.
Construction
Iroko wood is also used in building work, especially for strong parts like beams and columns. Because it is so strong and heavy, it works well in buildings that need to support a lot of weight.

Disadvantages of Iroko Wood
While iroko wood has many good points, it also has some drawbacks that might not suit everyone:
1. Heavy and Hard to Work With
Iroko is strong but very heavy, which can make it hard to move or cut, especially for detailed work.
2. Costly for Small Projects
It’s cheaper than teak but still quite expensive, especially for small jobs or if you’re on a budget. Shipping can also add to the cost.
3. Uneven Texture
The grain of iroko can be uneven, making it harder to cut, shape, or get a smooth finish.
4. Gets Darker Over Time
Iroko starts off golden-brown but darkens with age and sunlight, which some people might not like.
5. Needs Careful Handling
It can get scratched or dented if not handled well, and needs proper finishing to keep it looking nice.
