Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to wavy grain, sometimes interlocked. Features a coarse, uneven texture with a distinct oily or greasy feel. Shows cathedral figuring in some boards due to flat-sawing.
Color Description
Heartwood is typically a golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. It possesses a dull luster and can exhibit streaks of darker brown or black.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Exceptional resistance to rot, fungal decay, and termites due to high natural oil content. Highly weather-resistant.
Common Uses
Boat building (decks and trim), exterior furniture, high-end interior flooring, cabinetry, veneer, and turnery.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); extensively grown on plantations in tropical regions across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$25.00 - $40.00 per board foot for high-quality FEQ (First European Quality) boards.
Wood Age Estimate
The sample appears relatively new or recently sanded, showing minimal silver-gray patina typical of weathered outdoor teak. Visible accumulation of dust/residue suggests it part of a utilized deck or table.
Sustainability Status
Listed on the IUCN Red List as Endangered due to habitat loss and overexploitation; trade of Burmese teak is heavily restricted. Plantation-grown teak is widely available and often FSC certified.
Workability
Easy to work in most regards, though high silica content has a significant dulling effect on cutting edges.Glues well only after surface preparation (wiping with solvent) to remove surface oils.
Notable Features
Distinctive leather-like scent when freshly milled. High natural oil and silica content. Known for dimensional stability and very low shrinkage rates.
Finish Recommendations
Teak oil or tung oil to maintain color; marine-grade varnish for high-exposure areas. Often left unfinished to weather to a natural silver-gray.
Identification Confidence
High. The characteristic golden-brown hue, oily surface appearance, and specific grain texture are diagnostic for Tectona grandis, commonly used in the slatted construction shown.
