Common Name(s): Teak, Burmese Teak

Scientific Name: Tectona grandis

Distribution: Native to southern Asia;

Widely grown on plantations throughout tropical regions of Africa, Asia, and Latin America.

Tree Size: 100-130 ft (30-40 m) tall, 3-5 ft (1-1.5 m) trunk diameter

Average Dried Weight: 41 lbs/ft3 (655 kg/m3)

Specific Gravity (Basic, 12% MC): .55, .66

Janka Hardness: 1,070 lbf (4,740 N)

Modulus of Rupture: 14,080 lbf/in2 (97.1 MPa)

Elastic Modulus: 1,781,000 lbf/in2 (12.28 GPa)

Crushing Strength: 7,940 lbf/in2 (54.8 MPa)

Shrinkage: Radial: 2.6%, Tangential: 5.3%, Volumetric: 7.2%, T/R Ratio: 2.0

Color/Appearance: Heartwood tends to be a golden or medium brown, with color darkening with age.

Grain/Texture: Grain is straight, though it can occasionally be wavy or interlocked. Coarse, uneven texture and moderate to low natural luster. Raw, unfinished wood surfaces have a slightly oily or greasy feel due to natural oils.

Endgrain: Ring-porous or semi-ring-porous; large to very large solitary earlywood pores, medium to large latewood pores, few; solitary and in radial multiples of 2-3; tyloses and other heartwood deposits (light-colored) common; medium rays visible without lens, spacing normal; parenchyma vasicentric, and banded (marginal), with bands sometimes wide enough to enclose entire earlywood pores.

Rot Resistance: Teak has been considered by many to be the gold standard for decay resistance, and its heartwood is rated as very durable. Teak is also resistant to termites, though it is only moderately resistant to marine borers and powder post beetles.

Workability: Easy to work in nearly all regards, with the only caveat being that Teak contains a high level of silica (up to 1.4%) which has a pronounced blunting effect on cutting edges. Despite its natural oils, Teak usually glues and finishes well, though in some instances it may be necessary to wipe the surface of the wood with a solvent prior to gluing/finishing to reduce the natural oils on the surface of the wood.

Odor: Teak can have a leather-like scent when freshly milled.

Allergies/Toxicity: Although severe reactions are quite uncommon, Teak has been reported as a sensitizer. Usually most common reactions simply include eye, skin, and respiratory irritation, as well as other health effects, such as pink eye, rash, nausea, asthma-like symptoms, and vision effects. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Despite its widespread cultivation on plantations worldwide, Teak is very expensive. It is perhaps one of the most expensive lumbers on the market, at least for large-sized, non-figured wood. Other woods are more expensive, but are typically only available in small pieces, (i.e., Gaboon Ebony or Snakewood), or they are valued solely for the figure of their grain (i.e., burl woods, Pommele Sapele, or Waterfall Bubinga).

Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.

Common Uses: Ship and boatbuilding, veneer, furniture, exterior construction, carving, turnings, and other small wood objects.

Comments: Sometimes called Burmese Teak, this name is used to differentiate natural-grown trees (typically from Myanmar, aka Burma) from Teak grown on plantations. Used extensively in India and within its natural range for centuries, Teak has grown into a worldwide favorite. With its superb stability, good strength properties, easy workability—and most of all, its outstanding resistance to decay and rot—it’s no wonder that Teak ranks among the most desired lumbers in the world.

Much like the many names and knockoffs of Mahogany, the moniker “Teak” has been affixed and assigned to a number of different woods seeking acclaim. The usual procedure is to  take a wood bearing any degree of resemblance to Teak and insert a geographical location in front of the name. For instance, Cumaru is sometimes referred to as Brazilian Teak, while Rhodesian Teak bears little botanical relation to real Teak—Tectona grandis. The name Burmese Teak, however, does refer to genuine Teak.

Sailboat person: If the dimensions of the teak compression post are the same or better than the mast, it will be plenty strong however, the post mounts on the mast step in the bilge and therefore the structure of the mast step must be very strong, otherwise the mast will press down on the post and the post will press down on the mast step and put a huge strain on the structure in the bilge.

Anyone who can help ….
Can teak post be used as a mast support inside a cabin of a sailing boat ??? Is it strong enough ????
I was thinking if it is not strong enough – I can wrap it in carbon fibre…..
Thanks for your time….

Wrapping it in carbon fiber won’t work. Teak is strong and hard enough to use for your purpose.

Can I “seal” my Burmese Teak “finished” indoor furniture that currently requires frequent application of lemon oil. Without the lemon oil, the wood begins to turn pale or white. Many thanks for any resolution to my problem
