Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight grain with a coarse, uneven texture and a slightly oily or waxy feel. Some areas exhibit a slight shimmer and an open-pore structure characteristic of plain-sawn tropical hardwoods.
Color Description
Heartwood is a golden or medium brown, darkening with age and light exposure. Narrow sapwood is pale yellowish-white. It possesses a dull to moderate natural luster due to high oil content.
Hardness Rating
1,070 lbf (Medium Hardness)
Durability Rating
Very Durable. Exceptional resistance to rot, termites, and weathering due to high natural oil and silica content.
Common Uses
Ship and boat building (especially decks), outdoor furniture, high-end cabinetry, exterior construction, veneer, and turnery.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations throughout tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 USD per board foot depending on source and quality (FEQ grade).
Wood Age Estimate
The sample appears relatively fresh or recently surfaced, showing minimal deep oxidation or grey weathering typically seen in aged exterior teak.
Sustainability Status
Natural-grown teak from Myanmar (Burmese Teak) is subject to heavy trade restrictions and is on the IUCN Red List as Endangered; plantation-grown teak (FSC certified) is widely available and sustainable.
Workability
Generally easy to work, though the high silica content has a significant dulling effect on cutting edges. Glues well despite natural oils if the surface is cleaned with a solvent first.
Notable Features
Distinctive leather-like scent when freshly cut. Contains high levels of natural oils and silica. Highly stable with very low shrinkage rates after seasoning.
Finish Recommendations
Teak oil is the standard choice to maintain color. It can be left unfinished to weather to a silver-grey or finished with marine-grade varnish/lacquer if properly degreased.
Identification Confidence
High; the golden-brown hue, coarse open grain, and characteristic waxy surface texture are diagnostic of Tectona grandis.
