Workability
Azobé is extremely difficult to work due to its very high density and hardness. Carbide-tipped tools are essential, and cutting speeds should be kept low. Pre-drilling is mandatory for all fasteners. It glues with difficulty and finishes are rarely applied in structural uses. Dust control and PPE are strongly recommended.
Common Uses
Marine construction, bridges, railway sleepers, harbor works, heavy-duty decking, and industrial flooring.
What Makes Azobé Unique
Azobé is renowned for its exceptional strength, density, and resistance to wear, even in the most demanding environments. It is one of the most durable hardwoods available and is often selected for critical structural and marine applications where failure is not an option.
Why Choose Azobé
-
Extreme Durability: Outstanding resistance to rot, insects, and marine borers
-
Exceptional Strength: Suitable for the heaviest structural loads
-
Long Service Life: Performs for decades in harsh conditions
-
Minimal Maintenance: Often used unfinished in exterior and marine settings
Why You Might Not Choose Azobé
-
Very Difficult Workability: Extremely hard and dense
-
Heavy Weight: Challenging to transport and install
-
High Tool Wear: Rapidly dulls cutting edges
-
Limited Decorative Use: Primarily structural rather than aesthetic
Climate Performance & Acclimation
Azobé performs exceptionally well in all climates, particularly in wet, coastal, and marine environments. Proper seasoning and professional handling are essential due to its density.
Ideal for Heavy-Duty & Marine Projects
Its unmatched durability makes Azobé ideal for bridges, docks, piers, seawalls, railway sleepers, and industrial decking.
Color and Grain Stability
Azobé’s dark reddish-brown color remains stable over time, with minimal surface change. Weathering may dull the surface, but structural integrity remains unaffected.
