Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight to interlocked grain with a coarse, uneven texture. Visible vertical striations and occasional small knots with oil-rich pores.
Color Description
Currently weathered to a silvery-gray patina; original heartwood is golden to medium brown. Shows characteristic dark streaks and low luster due to high natural oil content.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Exceptional resistance to rot, termites, and fungal decay; highly resistant to moisture and weathering due to high silica and oil content.
Common Uses
Outdoor decking, boat building (yacht decks), outdoor furniture, exterior cladding, and high-end joinery.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown in plantations in tropical regions worldwide.
Market Value & Sustainability
Estimated Market Value
$30.00 - $45.00 per board foot for premium Burmese or plantation-grown boards.
Wood Age Estimate
Exposure estimate: 5 to 10 years of outdoor weathering without treatment, based on the depth of the gray silvering and visible grain erosion.
Sustainability Status
Natural-grown Burmese Teak is restricted; plantation-grown Teak is widely available and FSC-certified. Vulnerable status in some native regions.
Workability
Generally easy to work but high silica content causes rapid dulling of cutting edges. Glues moderately well despite oils; pre-drilling required for screws.
Notable Features
Distinctive leather-like scent when freshly cut; naturally oily feel; high silica content and excellent dimensional stability.
Finish Recommendations
Teak oil or penetrating sealers. If maintaining the gray look, leave unfinished. To restore color, deep cleaning and sanding followed by high-quality UV-inhibiting oil.
Identification Confidence
High. The weathering pattern, broad pore structure, and vertical grain orientation are diagnostic of Teak used in an exterior decking or cladding application.
