21.05.2025. Stability is a critical factor in wood processing since material movement can lead to defects, rework and product returns.
Pain Point: Some wood species warp, shrink, or expand unpredictably, making them unsuitable for precision applications.
Solution: African hardwoods such as Bossé, Kosipo, Tali and Afrormosia remain stable under varying humidity conditions, making them ideal for flooring, doors, and fine joinery.
Woods with low shrinkage rates allow for predictable performance, ensuring that finished products retain their shape and structural integrity over time.
This makes them particularly valuable in export markets, where climate fluctuations can cause dimensional instability in lower-quality species.

#WhyWoodMatters : Selecting stable African hardwoods ensures that products maintain their form and function over time, reducing returns and enhancing brand reputation.
Dimensional instability in wood can lead to warping, swelling, or shrinking, resulting in product failures and customer dissatisfaction.
Such issues are particularly problematic in applications requiring precise dimensions, like flooring or cabinetry.
