Teak Local Name: Teca

Botanical Name: Tectona grandis

Family: Verbenaceae

The Tree: Teak is very fast growing, and on favorable sites may reach 130 to 150 feet in height with clear boles to 80 to 90 feet. The trunks are cylindrical to fluted and may reach 3 to 5 feet in diameter.

Status: Teak has been heavily exploited for more than a century and is increasingly difficult to obtain. It is listed as endangered.

The Wood: Teak is a beautiful golden to dark brown, sometimes reddish brown, with a straight grain, sometimes wavy.

Teak is rich in natural oils, is easily worked, and dresses to a very smooth finish.
Because of its natural oils, teak is very durable and resistant to moisture and the drying effects of exposure to weather. Teak is unique in that it does not cause rust or corrosion when in contact with metal.

Uses: Teak is a very valuable wood and is prized throughout the world. It is sought for the decks, trim and detail work in expensive boats, and fine furniture, flooring, carving, joinery, cabinetwork, paneling, turnery and veneer.

Environmental Profile

This species is reported to be relatively secure, with little or no threat to its population within its natural growth range (Source - World Conservation Monitoring Center - 1992 ).

Perfil Ambiental

Esta especie es relativamente segura con poca o ninguna amenaza a su poblacion dentro de su habitat natural (Fuente - World Conservation Monitoring Center - 1992)

Teak is reported to be indigenous to India, Burma, Thailand, Indochina and Java, but it has been extensively planted for timber or as an ornamental within its natural range and throughout the tropical regions of the world, including East and West Africa, the West Indies, from Cuba and Jamaica to Trinidad, and from Panama to Brazil. It is also grown in southern Florida. The species has also been cultivated experimentally or at low elevations in Puerto Rico.

Tree Data
Teak trees are reported to attain heights of 130 to 150 feet (39 to 45 m) under favorable conditions. Stems are reported to be often clear of branches to 80 to 90 feet (24 to 27 m) high. Trunk diameters are reported to be often from 36 to 60 inches (90 to 150 cm), and older trees are typically fluted and buttressed. Plantation trees are reported to grow to heights of 150 feet (45 m), and can be ready for harvesting after only 60 years. Teak logs are reported to be very heavy, and are rather difficult to transport. Standing trees are sometimes girdled and left to stand for two to eight years before they are harvested. This practice is reported to allow moisture in the tree to dissipate, and hence make the logs less heavy and easier to transport.

Sapwood Color
The clearly demarcated sapwood is white to pale yellow in color.

Heartwood Color
The heartwood in its purest form, is a uniform dark golden-brown, without markings. But most other heartwood found in this species is dark golden yellow, which turns into rich brown with darker, chocolate-brown markings upon exposure. There is moderate to high color variation between boards.

The grain is generally straight, but occasionally wavy.

Texture is coarse and uneven. The wood is somewhat greasy and may contain white shiny deposits.

Wood surfaces are dull, and the material is reported to have an oily feel.

Freshly-milled wood is reported to have an odor similar to that of leather, but there is no distinctive taste.

Ease of Drying
The wood is reported to dry well, but slowly.

Drying Defects
Large variations in drying rates may occur. The wood may also change color temporarily upon kiln drying.

Kiln Schedules
T10 - D4S (4/4); T8 - D3S (8/4) US
Schedule H (4/4) - United Kingdom

Movement in Service
Seasoned wood is reported to have very good dimensional stability, and retains its shape well after manufacture.

T/R Ratio
This indicator is more meaningful if it is used together with other drying information and actual shrinkage data in the tangential and radial directions. (Refer to the Numerical Values window).

Natural Durability
Natural resistance to attack by decay fungi and termites is reported to be very high in the heartwood, and teak's resinous oil is reported to act as a natural insect repellant. The sapwood is susceptible to attack by powder-post beetles.

Resistance to Impregnation
The heartwood is reported to be extremely resistant to preservative treatment. The sapwood also has low permeability, but the wood has a high natural resistance to decay which tends to offset its poor response to preservative treatment.

Resistance to Chemicals
The timber is reported to be resistant to water and numerous chemical reagents, including acids, and will not cause rust or corrosion when it comes in contact with metals.

Toxic Constituents
Sawdust from machining operations is reported to cause skin irritation in some individuals.

Silica Content
The timber is siliceous. Amount is reported to vary, but may be up to 1.4% (of ovendry weight). Silica level of 0.05% is considered to be enough to affect the machining properties of wood.

Blunting Effect
The wood exerts severe blunting effect on cutting edges. Tungsten carbide-tipped cutters are recommended.

Cutting Resistance
The wood is fairly difficult to saw and tungsten-carbide cutting tools are recommended.

Cutting angles should be reduced to 20 degrees for best results.

The material is moderately easy to turn, but cutters tend to dull rapidly and severely.

Moulding properties are reported to be generally good.

Boring operations are reported to be fairly easy, but cutting edges may dull rapidly.

Routing & Recessing
Routing properties are reported to be moderately easy, but cutting edges dull rapidly.

The material responds well to sharp cutters in mortising operations.

The material is reported to carve well.

Freshly sanded or planed surfaces are reported to be fairly easy to glue.

Pre-boring is recommended in nailing.

Pre-boring is recommended in screwing.

Sanding qualities are reported to be generally good, but abrasives tend to be clogged. Frequent sandpaper changes are usually necessary.

The wood has satisfactory polishing properties.

The wood takes stain well, but natural oils in the wood may interfere with adhesion and drying of some finishes. Removing surface resins with a solvent that is compatible with the finish to be used is suggested to reduce the wood's tendency to repel finish coats.

Varnishing properties are fairly good. (See notes under 'Staining').

The wood has fairly good painting properties. (See notes under 'Staining').

Steam Bending
Steam bending properties are rated as moderate.

Response to Hand Tools
The wood responds well to hand tools but cutting edges should be kept very sharp.


Strength Properties
Teak has high bending strength in the air-dry condition (about 12 percent moisture content). It compares favorably with American oak (Quercus ), which also has high bending strength. Compression strength parallel to grain in the air-dry condition is also high. Hardness is rated as medium, and weight and density are high.

Datos del Arbol
