Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight grain with a coarse, uneven texture. Occasional wavy or interlocked grain is present, with visible large open pores characteristic of tropical hardwoods.
Color Description
Heartwood is a golden or medium brown, darkening with age and light exposure. High natural luster and a slightly greasy or oily feel to the surface.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Exceptional resistance to rot, termites, and fungal decay due to its high natural oil and silica content.
Common Uses
Boat building (decks and trim), exterior furniture, high-end flooring, cabinetry, veneer, and turnings.
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
$25.00 - $45.00 per board foot depending on grade and whether it is old-growth or plantation-grown.
Wood Age Estimate
N/A - Modern milled lumber with minimal oxidation or wear indicators.
Sustainability Status
Listed as Endangered on the IUCN Red List due to a population decline in its native range. Often available with FSC certification from plantation sources.
Workability
Generally easy to work with hand and machine tools, though its high silica content has a significant dulling effect on cutting edges. Glues better when surfaces are wiped with a solvent to remove natural oils.
Notable Features
Distinctive leather-like scent when freshly cut. High oil and silica content provide excellent slip-resistance and weatherproofing.
Finish Recommendations
Teak oil or Danish oil to maintain natural appearance; can also be left unfinished to weather to a silver-gray. High-solids polyurethanes can be used if surface oils are properly removed.
Identification Confidence
High; the combination of the golden-brown hue, large open pores, and slightly greasy surface texture is characteristic of Tectona grandis.
