Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to slightly wavy with a coarse, uneven texture; displays a flat-sawn cathedral pattern with visible earlywood and latewood bands and open pores.
Color Description
Heartwood is a golden or medium brown, darkening with age and light exposure; sapwood is pale yellowish-white. It has a dull to moderate natural luster and an oily feel.
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 applications (boat decks and trim), outdoor furniture, high-end flooring, cabinetry, veneer, and exterior joinery.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown on plantations in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot depending on source and grade (FEQ - First European Quality).
Wood Age Estimate
The sample appears recently milled or well-maintained, suggesting a wood age of 1-5 years post-processing, though the tree itself likely matured over 40-60 years.
Sustainability Status
Listed as Endangered on the IUCN Red List due to native habitat loss; FSC-certified plantation teak is widely available and preferred.
Workability
Generally easy to work but high silica content significantly dulls cutting edges; glues and finishes well but natural oils may require surface wiping with a solvent prior to bonding.
Notable Features
Distinctive leather-like scent when freshly cut; feels greasy or oily to the touch; high silica content and natural resistance to moisture.
Finish Recommendations
Teak oil or Danish oil is recommended to enhance natural color; if film-forming finishes like polyurethane are used, wipe with acetone first to remove surface oils.
Identification Confidence
High; the combination of golden-brown hue, large open pores, oily texture, and distinct growth ring patterns is characteristic of Tectona grandis.
