Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to slightly wavy with an open-pored texture; some pieces exhibit an interlocked or irregular grain depending on the growth conditions.
Color Description
Heartwood is typically a golden or medium brown, while sapwood is a distinct pale yellowish-white. It often features dark streaks and possesses a natural luster that deepens to a rich silvery-gray if left unfinished outdoors.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptionally resistant to rot, termites, and fungal decay due to high natural oil and rubber content.
Common Uses
Marine applications (boat decks), outdoor furniture, high-end flooring, cabinetry, veneer, and exterior construction.
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
Ranges from $25.00 to $50.00 per board foot depending on grade (FEQ) and origin (plantation vs. old-growth).
Wood Age Estimate
Relatively fresh-cut or recently surfaced material, likely less than 5 years old based on the lack of silvering and sharp, modern mill marks.
Sustainability Status
Listed on the IUCN Red List as Endangered due to habitat loss; however, FSC-certified plantation teak is widely available and sustainable.
Workability
Generally easy to work but high silica content significantly dulls cutting edges; glues and finishes well if surface oils are wiped with a solvent first.
Notable Features
Distinctive leather-like scent when freshly cut; naturally oily feel; high silica content and excellent dimensional stability.
Finish Recommendations
Teak oil or tung oil to enhance natural color; marine-grade varnish for high-exposure areas; often left unfinished for outdoor use.
Identification Confidence
High; the golden-brown hue, characteristic open-pore structure, and oily surface texture are hallmark indicators of Tectona grandis.
