Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight with occasional wavy patches; course and uneven texture with a characteristic oily feel and visual cathedral figure in the center.
Color Description
Golden to medium brown heartwood that darkens with age; sapwood is pale yellowish-white. Shows a muted luster and can develop a silver-grey patina if weathered.
Hardness Rating
1,070 lbf (Medium Hardness)
Durability Rating
Very Durable; exceptional resistance to rot, termites, and weathering due to high natural oil content.
Common Uses
Outdoor furniture, boat building (decks and trim), high-end cabinetry, flooring, and veneer.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown in plantations globally.
Market Value & Sustainability
Estimated Market Value
$30.00 to $50.00 per board foot depending on grade and legality/certification.
Wood Age Estimate
Estimated 20-40 years since harvest based on the surface oxidation and the depth of the golden-brown color variation.
Sustainability Status
IUCN Red List: Endangered (Wild); FSC certified plantation teak is widely available and preferred for sustainability.
Workability
Generally good, though high silica content can rapidly dull cutting edges. Glues well if surfaces are wiped with solvent to remove natural oils first.
Notable Features
Distinctive leather-like scent when freshly cut; heavy natural oils make it naturally water-resistant; high silica content.
Finish Recommendations
Teak oil or Danish oil to maintain natural color; lacquer or polyurethane can be used but may require a sealer to prevent oil interference.
Identification Confidence
High; the combination of large pores, golden-brown color, oily surface appearance, and specific grain spacing is characteristic of Tectona grandis.
