Grain Pattern

Predominantly straight, fine-to-medium texture, with subtle interlocked or wavy grain and occasional dark streaking; likely flat-sawn.

Color & Appearance

Golden to medium brown heartwood with darker brown streaks and limited pale sapwood. Teak develops a richer bronze-brown patina; finish and lighting strongly affect appearance.

Hardness (Janka)

1,070 lbf Janka — Medium.

Durability & Decay Resistance

Very Durable; naturally resistant to decay, moisture, and many insects, though exposed weathering eventually silvers it.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $12–$30 per board foot for ordinary kiln-dried stock; premium old-growth or figured material may cost more.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
Not reliably determinable from this single finished surface; visible darkening suggests finish oxidation or use, not necessarily substantial age.

Common Uses

Outdoor and indoor furniture, decking, boatbuilding, flooring, cabinetry, turning, and veneer.

Geographic Origin

Native to South and Southeast Asia; plantation-grown widely in tropical regions.

Workability

Generally machines and sands well, though silica and natural oils can dull tools and complicate gluing; predrilling is advisable.

Finish Recommendations

Clean and lightly abrade; use a compatible marine varnish, polyurethane, or teak oil. Remove surface oils before gluing or coating.

Notable Features

Oily feel, characteristic mild odor, high dimensional stability, and strong weathering performance.
