Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight grain with occasional wavy or interlocked patterns; presence of small dark streaks and distinct oily texture visible in the flat-sawn orientation.
Color Description
Heartwood is a golden brown with darker streaks; sapwood is pale yellowish-white. The wood has a dull luster due to natural oils and typically darkens to a rich medium-to-dark brown with age.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptional resistance 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 flooring, cabinetry, veneer, and exterior joinery.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown in plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$40.00 - $65.00 per board foot for high-quality FEQ (First European Quality) Burmese teak.
Wood Age Estimate
20-40 years based on secondary oxidation and surface patina, suggesting this is older reclaimed or weathered stock rather than fresh lumber.
Sustainability Status
Listed as endangered on the IUCN Red List (wild populations); plantation-grown teak is widely available and FSC certified; Burmese teak is often subject to strict trade sanctions.
Workability
Generally easy to work but high silica content causes severe dulling of cutters. Glues well only after surface oils are wiped with solvent (acetone).
Notable Features
Distinctive leather-like scent when freshly cut; high natural oil content; grittiness due to silica; excellent dimensional stability.
Finish Recommendations
Teak oil or tung oil to preserve natural appearance; polyurethane is possible if the surface is thoroughly degreased with acetone prior to application.
Identification Confidence
Medium-High; the characteristic golden-brown hue, presence of longitudinal dark streak 'honey-veins', and the distinct oily surface texture under light are hallmark indicators of Tectona grandis.
