Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight to slightly wavy; coarse texture with a visible linear grain pattern typical of flat-sawn or rift-sawn tropical hardwood.
Color Description
Currently weathered to a silvery-grey patina due to UV exposure; naturally a golden-brown heartwood with darker streaks. High natural oil content prevents a dull look despite weathering.
Hardness Rating
1000-1150 lbf (Medium Hardness)
Durability Rating
Very Durable; exceptionally resistant to rot, termites, and fungal decay due to high natural silica and oil content. Ideal for direct outdoor exposure.
Common Uses
Outdoor furniture, boat decking, marine applications, exterior trim, and high-end flooring.
Geographic Origin
Native to Myanmar (Burma), India, and Thailand; widely grown in plantations across Southeast Asia, Africa, and Latin America.
Market Value & Sustainability
Estimated Market Value
$25.00 - $45.00 per board foot depending on grade and origin (Burmese vs. Plantation).
Wood Age Estimate
The heavy silvering and visible surface checking suggest the wood has been exposed to the elements for 5-10 years.
Sustainability Status
Burmese Teak is highly restricted/threatened (IUCN Red List); Plantation-grown Teak is widely available and FSC certified.
Workability
Generally works well but high silica content dulls cutting edges quickly; natural oils can interfere with glues and finishes if not cleaned with solvent first.
Notable Features
Distinctive leather-like scent when freshly cut; naturally oily feel; high dimensional stability which prevents warping in wet/dry cycles.
Finish Recommendations
Teak oil or penetrating sealers to maintain golden color; alternatively, leave unfinished to allow the silver patina to persist. Scuff-sanding is needed to remove weathered surface cells.
Identification Confidence
High; the silver-grey weathering pattern, linear grain texture, and typical application as outdoor park or patio slats are hallmark indicators of Tectona grandis.
