Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight grain with occasional wavy or interlocked patterns; characteristic oily texture and large, coarse pores giving a moderately open-grain appearance.
Color Description
Heartwood is a golden or medium brown, darkening with age. Sapwood is pale yellowish-white. It often shows dark streaks and a dulling of color if left untreated in sunlight.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptional resistance to rot, fungal decay, and termites due to high natural oil and silica content.
Common Uses
Marine applications (boat decks/trim), outdoor furniture, high-end flooring, veneer, cabinetry, and exterior construction.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown in plantations across Africa and the Americas.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot (varies by grade and provenance)
Wood Age Estimate
20-40 years since harvest; showing moderate oxidation and typical 'honey' patina of aged, reclaimed or long-stored lumber.
Sustainability Status
Near Threatened (IUCN); Burmese Teak is subject to trade restrictions/sanctions; FSC-certified plantation teak is the sustainable alternative.
Workability
Generally easy to work but high silica content provides a significant dulling effect on cutting edges; glues well regardless of oils if surfaces are pre-cleaned with solvent.
Notable Features
Distinctive leather-like scent when freshly cut; high natural oil content; feels slightly greasy to the touch; known for excellent dimensional stability.
Finish Recommendations
Teak oil or penetrating sealers are preferred; if using film-forming finishes like lacquer or polyurethane, wipe with acetone first to remove surface oils.
Identification Confidence
High; the combination of golden-brown color, characteristic coarse texture, ring-porous structure, and visible insect bore hole are highly indicative of Teak.
