Tectona grandis · Exotic/Tropical
- Type
- Exotic/Tropical
- Origin
- Native to South and Southeast Asia (India, Myanmar, Thailand, Indonesia); widely cultivated in tropical plantations worldwide.
- Hardness
- 1,070 lbf (Medium)
- Durability
- Very Durable. Excellent natural resistance to decay, moisture, rot, fungi, and marine borers due to high natural resin and oil content.

Grain Pattern
Mostly straight to slightly wavy grain with open pores, fine dark mineral streaks, and a subtle flat-sawn cathedral arc near the center.
Color & Appearance
Golden-tan to light brown with muted greenish-grey undertones and dark brown streaks. Soft matte sheen with moderate chatoyance; typically darkens to a richer golden brown upon oiling and light exposure.
Hardness (Janka)
1,070 lbf (Medium)
Durability & Decay Resistance
Very Durable. Excellent natural resistance to decay, moisture, rot, fungi, and marine borers due to high natural resin and oil content.
Value & Sustainability
- Estimated Market Value
- $15.00 - $30.00 per board foot depending on grade, origin (Old-growth vs. Plantation), and board dimensions.
- Wood Age Estimate
- Freshly milled or recently surfaced lumber, likely under 5 years old based on clean, unoxidized surfaces and modern machine planing marks.
- Sustainability Status
- IUCN Endangered in native habitats due to overharvesting; plantation-grown teak is widely available and FSC-certified.
Common Uses
Outdoor furniture, boat building, marine decking, high-end interior furniture, cabinetry, flooring, and architectural millwork.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand, Indonesia); widely cultivated in tropical plantations worldwide.
Workability
Generally works well with hand and power tools, but high silica content quickly dulls cutting edges. Takes glue moderately well after wiping surface oils with solvent.
Finish Recommendations
Teak oil or penetrating marine oils work best. For film finishes like polyurethane or lacquer, solvent-wipe surface oils with acetone or denatured alcohol prior to application.
Notable Features
Distinctive oily or waxy feel on raw surfaces, mild leather-like or rubbery scent when freshly cut, excellent dimensional stability.
