Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Usually straight, though occasionally wavy or interlocked; coarse, uneven texture with a naturally oily or greasy feel; flat-sawn orientation visible in sample.
Color Description
Heartwood is typically golden or medium brown, darkening with age and light exposure to a richer deep brown. Sapwood is a distinct pale yellowish-white. Shows moderate luster.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; extremely resistant to rot, termites, and weathering due to 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 South and Southeast Asia (India, Myanmar, Thailand); extensively grown on plantations worldwide in tropical regions.
Market Value & Sustainability
Estimated Market Value
Ranges from $25.00 to $50.00 per board foot depending on grade and origin (FEQ - First European Quality is highest).
Wood Age Estimate
Relatively recent/modern kiln-dried lumber; lacks the deep patina of antique reclaimed teak, showing fresh machine marks and light oxidation.
Sustainability Status
Not CITES listed; IUCN Red List classifies it as Endangered in native habitats, but plantation-grown FSC-certified sources are widely available.
Workability
Generally easy to work with tools, though the high silica content is known for a severe dulling effect on cutting edges. Glues well if surface oils are wiped with solvent first.
Notable Features
Distinctive leather-like scent when freshly cut; exceptionally high stability (low shrinkage); contains natural silica and high oil content.
Finish Recommendations
Teak oil or Danish oil to preserve natural color; can be left unfinished to weather to a silver-grey; film-finishes like lacquer require surface degreasing.
Identification Confidence
High; the characteristic golden-brown hue, large open pores containing white silica deposits, and the visible oily surface texture are diagnostic for Tectona grandis.
