Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight grain with an oily, coarse texture; exhibits a flat-sawn appearance with some darker streaks and a somewhat uniform, porous open grain structure.
Color Description
Heartwood is a golden to medium brown, darkening with age to a rich, dark brown. The sapwood is typically a pale yellowish-white and clearly demarcated. It has a dull to medium luster and a characteristic oily feel.
Hardness Rating
1,070 lbf (Medium Hardness)
Durability Rating
Very Durable; famous for its exceptional resistance to rot, termites, and fungal decay due to high natural oils and silica content. Extremely weather-resistant.
Common Uses
Boat building (decks and trim), high-end outdoor furniture, flooring, veneer, cabinetry, and exterior construction where longevity and weather resistance are required.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand, Laos); widely grown on plantations throughout tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
Ranges from $25.00 to $50.00 per board foot depending on grain quality (FEQ - First European Quality), width, and sustainability certification.
Wood Age Estimate
The sample appears to be seasoned reclaimed or old stock boards, estimated between 20 to 50 years old based on the deep oxidation, surface grime, and classic patina.
Sustainability Status
Listed as Endangered on the IUCN Red List due to population reduction in native forests; CITES Appendix II (specifically for populations in certain regions). FSC-certified plantation teak is available.
Workability
Generally easy to work with hand and machine tools, though the high silica content can have a significant dulling effect on cutting edges. Glues well following surface preparation to remove surface oils.
Notable Features
Distinctive leather-like scent when freshly cut. High natural oil and rubber content makes it water-repellent and resistant to chemical degradation.
Finish Recommendations
Best finished with Teak Oil or Danish Oil to maintain its natural luster. Epoxies and polyurethanes can be used but usually require a surface wipe with a solvent like acetone to ensure adhesion.
Identification Confidence
Medium-High. The characteristic golden-brown color, oily surface texture, and open grain visible in the end-grain/face-grain transition are classic indicators of Tectona grandis.
