Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight grain with an open-porous texture; some pieces may exhibit wavy or interlocked grain. The surface shows a coarse, uneven texture typical of weather-beaten tropical timber.
Color Description
Heartwood is typically golden or medium brown, darkening with age. This weathered sample shows silver-gray oxidation on the surface with underlying streaks of warm brown and dull yellow.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Exceptional resistance to rot, fungi, and termites due to high natural oil and rubber content. Highly weather-resistant.
Common Uses
Outdoor furniture, boat building (decks), 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
$30.00 - $50.00 per board foot for high-quality Burmese Teak; Plantation Teak is lower.
Wood Age Estimate
Estimated 5-10 years of outdoor exposure based on the silver-gray 'teak patina' and surface checking/weathering marks.
Sustainability Status
Vulnerable (IUCN Red List). Natural growth Teak from Myanmar is heavily restricted; Plantation-grown Teak is widely available and FSC certified.
Workability
Generally easy to work but high silica content (up to 1.4%) has a severe dulling effect on cutting edges. Glues well despite high oil content if surfaces are cleaned with solvent first.
Notable Features
Distinctive leather-like scent when freshly cut; high natural oil and rubber content; feels slightly oily or greasy to the touch.
Finish Recommendations
Teak oil or tung oil to maintain color; alternatively, leave unfinished to allow it to weather to a natural silver-gray. Marine-grade varnish for boat applications.
Identification Confidence
Medium-High. The combination of large open pores, silver-gray weathering pattern, and visible oily residue in the grain is characteristic of Tectona grandis.
