Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight grain with occasional wavy or interlocked patterns; frequent dark streaks from silica or natural oils. Flat-sawn texture visible in sample.
Color Description
Heartwood is a golden or medium brown that darkens with age; sapwood is pale yellowish-white. Often features a dull luster and oily surface.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptionally resistant to rot, termites, and weathering due to high natural oil and rubber content.
Common Uses
Boat building (decks and trim), outdoor furniture, high-end cabinetry, flooring, veneer, and exterior joinery.
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
$25.00 - $45.00 per board foot depending on source and grade.
Wood Age Estimate
Recently milled or rough-cut (less than 1 year); shows fuzzy saw marks and lacks the deep silver patina of aged exterior teak.
Sustainability Status
Large-scale plantation growth improves availability; listed as 'Endangered' on the IUCN Red List due to natural forest decline; some regions are CITES Appendix II listed.
Workability
Generally easy to work but high silica content dulls cutting edges rapidly. Glues can be difficult due to natural oils; solvent wiping is required before bonding.
Notable Features
Distinctive leather-like odor when freshly cut; exceptionally high oil content provides waterproof properties and a greasy feel.
Finish Recommendations
Teak oil or Danish oil to maintain natural appearance; clear lacquer can be used if surface oils are first removed with mineral spirits.
Identification Confidence
High; the golden-brown hue, characteristic oily surface texture, and visible grain streaks in this rough-sawn state are classic indicators of Tectona grandis.
