Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Typically straight to slightly wavy grain with an oily feel and large pores; rift and flat sawn characters are visible here with subtle ribbon figure.
Color Description
Golden to medium brown heartwood that darkens with age; sapwood is pale yellowish-white. Shows a dull to moderate luster.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable: Highly resistant to rot, termites, and fungal decay due to high natural oil content.
Common Uses
Boat building (decks and trim), outdoor furniture, high-end cabinetry, flooring, and exterior joinery.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown in plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 to $50.00 per board foot (Premium grade)
Wood Age Estimate
Modern milling (less than 10 years old based on sharp edges and lack of deep oxidation or silvering).
Sustainability Status
IUCN status: Endangered (for wild teak); CITES Appendix II (some regions); FSC-certified plantation teak is commonly available.
Workability
Generally easy to work with hand and machine tools, though high silica content can dull blades quickly. Glues well if surfaces are wiped with solvent first.
Notable Features
Distinctive leather-like odor when freshly cut; exceptionally high natural oil and silica content; greasy feel to the touch.
Finish Recommendations
Teak oil or Danish oil to preserve natural appearance; if film-forming finishes like polyurethane are used, a sealer or solvent wipe is required to remove surface oils.
Identification Confidence
High: The characteristic golden-brown color, large open pores, slightly greasy surface texture, and grain structure are definitive hallmarks of Tectona grandis.
