Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Generally straight to slightly wavy with a flat-sawn cathedral figure visible; texture is coarse and uneven with a distinct oily feel.
Color Description
Heartwood is a golden or medium brown that darkens with age; sapwood is pale yellowish-white. Shows a muted luster and characteristic streaking.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptional resistance to rot, termites, and fungal decay due to high natural oil content.
Common Uses
Boat building (decks and trim), high-end outdoor furniture, exterior construction, flooring, and veneer.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$25.00 - $45.00 per board foot depending on source and grade.
Wood Age Estimate
Relatively fresh milled material; the light golden-tan color suggests it has not yet undergone significant UV oxidation or silvering.
Sustainability Status
IUCN Red List: Endangered (Wild); widely available via FSC-certified plantations. CITES: Not listed.
Workability
Generally easy to work but high silica content significantly dulls cutting edges; glues well if surfaces are wiped with solvent to remove natural oils.
Notable Features
Distinctive leather-like odor when freshly cut; high natural oil and silica content; greasy feel to the touch.
Finish Recommendations
Natural teak oil to replenish surface oils; can be left unfinished to weather to a silver-gray. Lacquers may have adhesion issues.
Identification Confidence
High; the combination of golden-brown hue, large open pores, 'oily' surface appearance, and cathedral grain is diagnostic for Tectona grandis.
