Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight grain with a coarse, open-pore texture; some waves may be present in the flat-sawn sections
Color Description
Golden-brown heartwood that darkens with age and exposure to light; sapwood is pale yellowish-white. It has a dull to medium luster and an oily feel.
Hardness Rating
1070 lbf (Medium)
Durability Rating
Very Durable; excellent resistance to decay, termites, and weathering due to high natural oil and silica content
Common Uses
Marine applications (boat decks), outdoor furniture, high-end cabinetry, flooring, and joinery
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown in plantations across Africa and Latin America
Market Value & Sustainability
Estimated Market Value
Approximately $25.00 - $45.00 per board foot depending on source and quality
Wood Age Estimate
Estimated 20-40 years based on the deep oxidation and golden-brown patina of the finished surface
Sustainability Status
Large-scale plantation growth available; wild-grown Teak is increasingly restricted; listed as Endangered on the IUCN Red List due to population declines
Workability
Generally easy to work with tools, though high silica content dulls cutting edges quickly. Glues well if surfaces are wiped with solvent to remove surface oils.
Notable Features
Distinctive leather-like odor when freshly cut; naturally high in oils and silica; resistant to acids and moisture
Finish Recommendations
Teak oil or tung oil to maintain natural appearance; can be finished with lacquer or polyurethane if surfaces are properly degreased first
Identification Confidence
High; the combination of the golden-brown color, distinct long vessels (open pores), and characteristic oily appearance are hallmark features of Tectona grandis.
