Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to slightly wavy; features an open-pore texture and a somewhat oily or greasy feel across the face grain.
Color Description
Heartwood is typically golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. This sample shows weathering to a silvery-grey patina characteristic of outdoor exposure.
Hardness Rating
1,070 lbf (Medium Hardness)
Durability Rating
Very Durable; exceptional resistance to rot, termites, and decay due to high natural oil and silica content. Highly weather-resistant.
Common Uses
Boat building (decks and trim), outdoor furniture, high-end exterior joinery, flooring, and veneers.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations throughout 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 highest value).
Wood Age Estimate
The sample appears to be from a piece of lumber that has been aged or weathered for 5-10 years, evidenced by the silver-grey oxidation on the surface.
Sustainability Status
Listed on the IUCN Red List as Endangered (natural forests). FSC-certified plantation teak is widely available and preferred for sustainability.
Workability
Generally easy to work with hand and machine tools, but the high silica content has a significant dulling effect on cutting edges. Glues well only after surface oils are wiped with solvent.
Notable Features
Distinctive leather-like scent when freshly cut. Contains high levels of natural rubber and silica, making it naturally water-repellent and slip-resistant.
Finish Recommendations
Teak oil or tung oil are recommended to maintain natural color. Use a sealer if gluing. If left unfinished, it will naturally weather to the grey color seen in the photo.
Identification Confidence
Medium-High; the coarse, open-pore grain structure combined with the specific silvery-grey weathering pattern is classic for Tectona grandis.
