Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to slightly wavy grain with a coarse, uneven texture and visible ribbon-like vessel lines
Color Description
Heartwood is typically a golden or medium brown, darkening with age and exposure. Sapwood is a pale yellowish white. The sample shows significant silver-grey weathering (patina) towards the bottom due to UV exposure.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptionally resistant to rot, termites, and fungal decay due to high natural oil and silica content
Common Uses
Marine construction, boat decking, outdoor furniture, premium flooring, veneer, and exterior joinery
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand, Laos); widely grown on plantations in Africa and Latin America
Market Value & Sustainability
Estimated Market Value
Typically $25.00 to $50.00 per board foot depending on grade and origin (FEQ Burmese Teak commands the highest prices)
Wood Age Estimate
Estimated 15-30 years based on the deep oxidation, grey surface patina, and the presence of heavily rusted fasteners
Sustainability Status
IUCN Red List: Endangered (Wild); CITES: Not listed, but heavily regulated by EUTR and Lacey Act; FSC certified plantation teak is commonly available
Workability
Generally good with hand and machine tools, though the high silica content (up to 1.4%) has a severe dulling effect on cutting edges; glues well on freshly sanded surfaces
Notable Features
Distinctive leather-like odor when freshly cut; naturally oily feel; high silica content and exceptional dimensional stability
Finish Recommendations
Teak oil or tung oil are preferred to replenish natural oils; requires surface cleaning with acetone or denatured alcohol before gluing or finishing to remove surface oils
Identification Confidence
Medium-High; the coarse texture, oily appearance of the brown sections, specific weathering pattern, and use in a heavy-duty outdoor application with steel bolts are classic indicators of Teak.
