Wholesale African Bilinga Wood: Very Durable Golden Hardwood for Marine Works and Decking
Looking to buy African Bilinga Wood direct from the source? Bilinga (Nauclea diderrichii), known in the UK as Opepe, is a very durable golden hardwood with a long record in marine and civil engineering. It is used for jetties, lock gates, piling and bridge decks across Europe.
African Bilinga wood resists fungi, insects and marine borers without chemical treatment. Its warm orange colour also makes it popular for decking, cladding and outdoor furniture.
We supply African Bilinga wood as beams, baulks, planks, decking, railway sleepers and, where export is legally permitted, round logs and piles from legally managed, ethically harvested forest concessions in Cameroon, Gabon, Republic of Congo and Equatorial Guinea. Every order is inspected, documented and shipped in containers to your port, warehouse or job site.

Drying, Grading and Quality Control
Structural sizes are normally supplied fresh-sawn or air dried, because large heavy sections are not suited to kiln drying. Decking and flooring can be kiln dried to 12–18% on request. Grading follows ATIBT export rules or your project specification. Before loading, each parcel of Bilinga is checked for moisture content, dimensions, heartwood, grain and defects, and you receive loading photos and a packing list with the volume of every bundle.
Working With African Bilinga Wood: Practical Tips
- Interlocked Grain: Use sharp tools and reduced cutting angles to avoid tear-out.
- Drying: Bilinga dries fairly fast but can check in thick sizes.
- Fixings: Pre-drill for nails and screws, and use stainless fixings.
- Gluing: It glues reasonably well.
Ethically Harvested African Bilinga Wood From the Central African Forest Zone
All of our Bilinga comes from the Congo Basin forest zone, the second-largest tropical forest on earth. We buy only from operators that hold valid forest management or harvesting permits and follow national minimum felling diameters, so mature trees are selected and younger trees are left to grow.
Legal status: Not listed under CITES. Supplied from managed concessions with legality documents. You can check any species on the official CITES Checklist.
Each shipment can include a certificate of origin, phytosanitary certificate, legality and chain-of-custody documents, fumigation certificate where required, and a CITES export permit for listed species. This supports your due diligence under the EU Timber and Deforestation Regulations (EUTR/EUDR), the UK Timber Regulation and the US Lacey Act. FSC or PEFC certified volumes can be quoted on request, subject to availability.
