Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to slightly wavy with a coarse, open-pored texture and prominent dark mineral streaks; shown in a flat-sawn orientation
Color Description
Golden to medium brown heartwood that darkens with age; sapwood is pale yellowish-white. Shows a dull to oily luster and characteristic dark brown/black streaks
Hardness Rating
1070 lbf (Medium)
Durability Rating
Very Durable; exceptionally resistant to rot, termites, and fungal decay due to high natural oil and silica content
Common Uses
Boat building (decks and trim), outdoor furniture, high-end cabinetry, exterior construction, and veneer
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown on plantations in Africa and Latin America
Market Value & Sustainability
Estimated Market Value
$30.00 - $55.00 per board foot depending on origin (Burmese vs. Plantation) and grade
Wood Age Estimate
Modern lumber, likely kiln-dried; surface shows recent machine marks and minimal oxidation
Sustainability Status
Natural-growth Teak from Myanmar is restricted (CITES/IUCN Vulnerable); Plantation-grown (FSC certified) is widely available
Workability
Moderately easy to work but high silica content dulls cutting edges rapidly; oils can interfere with gluing and finishing if not prepared with a solvent
Notable Features
Distinctive leather-like scent when freshly cut; greasy or oily feel; contains high silica and natural oils providing weather resistance
Finish Recommendations
Teak oil or tung oil to maintain natural appearance; if lacquering or painting, surfaces must be wiped with acetone or denatured alcohol to remove surface oils
Identification Confidence
High; the golden-brown hue, prominent vessel lines, oily appearance, and typical dark mineral streaking are classic diagnostic features of Tectona grandis
