General Uses Top
Suggest a correction!Common products:
Heavy structural timber, flooring, decking, railway sleepers, marine timbers (piles, docks, piers), bridge timbers, utility poles, joinery, furniture, and veneer/plywood; sawdust and residues are used in local power generation.
Industrial and craft applications:
Suitable for load-bearing members in construction, for marine construction, and in heavy-duty flooring because of its density, high strength and stiffness, and resistance to fungal decay and insects.
Food and beverages (non-medicinal):
No documented culinary or beverage uses.
Colorants and tanning:
No documented use for dyes, inks, or tannins.
Fragrance and cosmetics:
No documented use for essential oils, oleoresins, or fragrance ingredients.
Properties relevant to use:
Air-dry density typically 0.90–1.10 g/cm³; high bending and compression strength; good dimensional stability; natural resistance to fungal decay and borers, attributable to extractives in the heartwood; grain typically interlocked; suitable for high-stress applications.
Wood and fiber:
Timber from the heartwood, typically marketed as Okan, is used in heavy construction, marine structures, sleepers, flooring, joinery, furniture, and veneer. Wood sawdust and chips are used for energy in areas of origin; the species is not used for fiber pulp or bast-fiber textiles.
Standards and regulation:
Timber may be listed under CITES Appendix II; trade is subject to CITES/wood-control regulations (e.g., EU Timber Regulation) and relevant national timber standards and grading rules for high-density hardwoods.
Sustainability and sourcing:
Classified as vulnerable to overexploitation by the IUCN (assessed 2019); supply is limited by national quotas and export controls in range countries; some areas have introduced management plans to promote sustainable harvesting.
