Grain Pattern
Straight grain predominantly, occasionally wavy or interlocked; coarse texture with a natural oily/waxy feel; shows distinct growth rings on end grain.
Color & Appearance
Heartwood is typically a golden or medium brown, darkening with age to a deep bronze. Sapwood is a pale yellowish-white. It possesses a moderate natural luster that can appear dull due to natural oils.
Hardness (Janka)
1,070 lbf (Medium)
Durability & Decay Resistance
Very Durable; internationally renowned for its superb stability and resistance to rot, termites, and fungal decay due to high natural oil content.
Value & Sustainability
- Estimated Market Value
- $30.00 to $50.00 per board foot, depending on grain quality (FEQ) and source (Burmese vs. Plantation).
- Wood Age Estimate
- Sample appears to be freshly milled or recently planed stock based on the crisp edges and light oxidation of the golden-brown surface.
- Sustainability Status
- Not CITES listed but IUCN Red List classifies some wild populations as Endangered. FSC-certified plantation teak is widely available and recommended.
Common Uses
Outdoor furniture, boat building (especially decking), flooring, veneer, carvings, and high-end cabinetry.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations across Africa and Latin America.
Workability
Generally easy to work but high silica content (up to 1.4%) has a severe dulling effect on cutting edges. Glues and finishes well, though surface oils may require wiping with solvent before bonding.
Finish Recommendations
Teak oil or tung oil to maintain natural look. For marine use, specialized marine varnishes are used. Avoid heavy film-forming finishes without proper surface preparation (acetone wipe).
Notable Features
Distinctive leather-like scent when freshly cut. High oil and silica content provide exceptional weather resistance but can cause skin irritation/dermatitis in some users.
