Teak
Tectona grandis • Exotic/Tropical

Grain Pattern
Typically straight to slightly wavy grain with an open, coarse texture and large pores. It often has a greasy or oily feel due to high natural oil content.
Color Description
Heartwood is a golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. It exhibits a dull luster but can show chatoyance when finished.
Hardness Rating
1070 lbf (Medium)
Durability Rating
Very Durable. Highly resistant to rot, fungi, and termites. Renowned for its exceptional weather resistance and natural durability in marine environments.
Common Uses
Furniture, boat building (decks and trim), exterior construction, flooring, cabinetry, veneer, and high-end outdoor joinery.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations across tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 to $50.00 per board foot depending on grade and origin (Burmese Teak is higher value than plantation-grown).
Wood Age Estimate
Modern sample, likely less than 5 years old based on the fresh milling marks and lack of deep oxidation/patina.
Sustainability Status
IUCN Red List: Endangered (Wild populations). CITES: Not listed, but trade in wild Burmese teak is highly regulated/restricted; plantation stock is widely available.
Workability
Generally easy to work with hand and machine tools, though the high silica content can dull cutting edges quickly. Glues well if surfaces are wiped with solvent first to remove natural oils.
Notable Features
Distinctive leather-like scent when freshly cut. High oil and silica content. Known for its remarkable stability and resistance to moisture. Can cause skin irritation or respiratory issues in some people.
Finish Recommendations
Teak oil is the traditional choice to maintain its natural appearance. For outdoor use, it can be left unfinished to weather to a silver-grey. If filming finishes like lacquer are used, a sealer is recommended to prevent oil bleed.
Identification Confidence
High. The golden-brown color, characteristic large open pores, visible grain streaks, and the oily appearance typical of Tectona grandis are clearly visible.
