Discover the Robustness and Beauty of Okan: An Excellence in Sustainability


In the world of hardwoods, Okan, a type of wood native to the lush forests of West Africa, occupies a prominent place. Prized for its impressive durability and unique aesthetics, this wood species is a popular choice for a variety of construction and design applications. In this blog we explore the properties, uses and benefits of Okan, and why it is an excellent alternative to other hardwoods such as Azobé.

The Majestic Origin of Okan

Okan, scientifically known as Cylicodiscus Gabunensis, originates in the tropical rainforests of West Africa. These trees reach an impressive height of up to 60 meters and have a straight, cylindrical trunk that is branch-free up to 20 to 30 meters, with a diameter between 90 and 300 cm. These growth characteristics testify to the strength and robustness of the wood.

Unique Features of Okan

Color and Appearance

Okan stands out for its unique color palette that varies from yellow to golden brown, sometimes with green hues. The heartwood often has an olive-green tint, and under the influence of light it can change to reddish-brown or even copper-colored. The sapwood, on the other hand, is light pink and forms a sharp contrast with the heartwood. These color changes add a dynamic and aesthetically pleasing element to the wood.

Durability and Weight

Okan is classified as durability class 1, which means that it is extremely durable and resistant to external influences. The wood is heavy, with a bulk density of approximately 950 kg/m³, which contributes to its strength and stability in structures.

Processing and Handling

Although Okan has a high density and a variable thread pattern, it can be easily machined with adapted cutting tools. Pre-drilling is recommended when screwing. A major advantage of Okan is that it does not require additional treatment to extend its lifespan, making it a low-maintenance option.

The versatile Applications of Okan

Okan's versatility makes it an ideal choice for a range of applications. This includes:

  1. Decking and Industrial Floors: Okan's durability and aesthetics make it ideal for decking and flooring, especially in industrial environments.
  2. Hydraulic Constructions: The wood is ideal for applications that come into contact with groundwater, fresh and salt water, such as piles and hydraulic structures.
  3. Bridge Construction and Sleepers: Okan's strength and durability make it a good choice for heavy structures such as bridges and railway sleepers.
  4. Outdoor use in Gardens and Decking: Okan is widely used in gardens and decking because of its resistance to weather influences and its attractive appearance.

Aesthetic Value

Okan's unique colors add natural beauty and warmth to any environment. The changing colors provide a vibrant palette that adds to the aesthetic appeal of the wood.

Ease of maintenance

Another important advantage of Okan is the minimal maintenance it requires. Its natural resistance to rot and harmful organisms means no frequent treatments or repairs are required.

Extensive Applications of Okan Hardwood

Revetments and Sheet Piles: Protection and Aesthetics

One of the most crucial uses of Okan hardwood is in the construction of revetments and sheet piles. These structures are essential for protecting waterways and coastlines from erosion and also provide support for earthworks.


Revetments, often used along waterfronts and banks, are intended to hold the soil in place and prevent further erosion. Okan hardwood is ideal for this because of its natural resistance to water and its durability class. The strength of Okan ensures that the revetments last a long time and can withstand the constant pressure of water and soil.
