Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight but occasionally wavy with a coarse, uneven texture and a naturally oily feel. Contains characteristic dark streaks of growth rings.
Color Description
Heartwood is a golden or medium brown, darkening with age and light exposure. Younger sapwood is a pale yellowish-white. It exhibits a dull luster due to natural oils.
Hardness Rating
1070 lbf (Medium)
Durability Rating
Very Durable: Highly resistant to decay, rot, and termites due to high silica content and natural oils. Excellent weathering properties.
Common Uses
Marine construction, boat building (decks), outdoor furniture, high-end veneering, flooring, and decorative cabinetry.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot depending on source and quality.
Wood Age Estimate
Modern (5-15 years), likely a plantation-grown specimen given the uniform grain and color consistency.
Sustainability Status
IUCN Red List: Endangered (wild populations); widely available via FSC-certified plantations. CITES Appendix II for some specific regions.
Workability
Generally easy to work with hand and machine tools, but natural silica content has a significant dulling effect on cutting edges. Glues well despite natural oils.
Notable Features
Distinctive leather-like scent when freshly cut. High oil and silica content. Known for exceptional dimensional stability when exposed to moisture.
Finish Recommendations
Natural teak oil or Danish oil to maintain the wood's inherent beauty. Avoid heavy film finishes which may peel due to surface oils.
Identification Confidence
High: The characteristic golden-brown hue, prominent longitudinal dark streaks, and coarse texture typical of Tectona grandis are clearly visible.
