orginates from the forests that grow in the Congo Basin in Gabon
Iroko is available in the forests of Precious Woods, located in the Congo Basin of Gabon. The tree attains diameters till about 100c m The trunks are straight and cylindrical and often have buttress root boards.
Freshly sawn Iroko has a buttery yellow to brown yellow color, and darkens to gold brown till dark brown after exposure. The heartwood has sometimes dark brown patches through the wood structure. The lighter colored sapwood is 50-100 mm thick and easy to distinguish. The wood structure is straight to irregular and often interlocked. The texture is medium coarse.
The machining of Iroko can be done easily, unless there is lime in the wood structure, which causes a blunting effect on the tools. Pre-drilling is recommended. The gluing and finishing are possible, but not easy. It dries rather quickly, with risks of cracking and deformation.
Thanks to the strength, durability and stability, Iroko is used for a wide range of applications, like door and window frames, doors and windows, cladding, exterior furniture, park benches and interior uses like furniture, carpentry and flooring. Iroko is mentioned on the SKH publication 99-05 which means that the timber is approved for production of KOMO certified door and window frames, doors and windows.
