The Strongest Wood In The World
Because of this special characteristic, not found in other trees, there has always been interest in using Teak wood for various types of furniture. Teak is not like other wood species and market demands and high price points have changed the standard specifications. Teakwood is derived from the teak tree, a type of birch that grows in tropical climates.
Teak wood is one of the strongest, most durable hardwoods in the world. The wood has a high oil content which gives it a natural resistance to rot and protects against insect infestation. Teak is also known for its ability to withstand almost any weather, which makes it a popular choice for boatbuilding. The oil in teak not only protects the wood, but also gives it a dark golden color and an earthy aroma. Teak wood tends to be a popular choice when it comes to outdoor furniture since it can usually endure temperature extremes without the use of preservatives. Since teak wood is usually grown on plantations in places like Thailand, India, and Indonesia, it is expensive. The teak tree is one of the tropical hardwood birches in the Verbenaceae family. The trees can grow to over 150 feet (45.7 m) tall and live to be about 100 years old.
Tectona grandis or teak is a commercial darling with wood that is durable and highly resistant to fungus and insects. The two remaining species are the Tectona philippinensis or Philippine teak and the Tectona hamiltoniana or Dahat teak.
Tectona grandis is native to India, Laos, Myanmar and Thailand. It is farmed in tropical countries around the world. The Philippine teak is native to the Philippines and is confined to the Philippine islands of Iling and Luzon. The Dahat teak is native to Myanmar and is confined to Myanmar’s “Dry Zone.”
Description of a Teak Tree
Original Source: Wikipedia — Teak
A teak tree, tectona grandis, is a large, deciduous tree up to 40m (131 ft) tall with gray to grayish brown branchlets. Leaves are ovate-elliptic to ovate, 15–45cm (5.9–17.7 in) long by 8–23cm (3.1–9.1 in) wide, and are held on robust petioles that are 2–4cm (0.8–1.6 in) long. Leaf margins are entire.
Fragrant white flowers are borne on 25–40 cm (10–16 in) long by 30 cm (12 in) wide panicles from June to August. The corolla tube is 2.5–3 mm long with 2 mm wide obtuse lobes. Tectona grandis sets fruit from September to December; fruits are globose and 1.2–1.8cm in diameter. Flowers are weakly protandrous in that the anthers precede the stigma in maturity and pollen is shed within a few hours of the flower opening. The flowers are primarily entomophilous (insect-pollinated), but can occasionally be anemophilous (wind-pollinated). A 1996 study found that in its native range in Thailand, the major pollinator were species in the Ceratina genus of bees.
The characteristics of the tree:

- Leaf width
- The skin on the tree like crocodile skin (typical of old teak tree)
- Molt or shed their leaves in the dry season
The characteristics of shaped wood, these characteristics are divided into two namely:
The characteristics of young teak
- Fiber and wood pores; Have fibers and larger pores
- Color of wood; wood is palw white
- Texture of wood; wood has a softer texture and lighter
- Circle Year; Having a circle of a few
- Durability of wood; wood rot easily especially in damp areas
The characteristics of teak Old
- Fibers and pores of wood; It has fiber and pore over a small meeting or
- Color of wood; Wood yellowish brown
- Texture Wood; Wood has a hard texture, smooth, and very beautiful
- Circle Year; Having a lot of rings
- Durability of wood; It has excellent resistance even teak wood is able to survive through decades without a loss.
The Dahat teak has a trunk that can grow up to 26 feet in height and to a diameter of about 27 inches. Its leaves usually grow in clusters of three and its flowers range from white to pale blue. The tree flowers from June to August. The Philippine teak grows to about 49 feet with leaves that measure 3 to 6 inches long and 1 to 3 inches wide and has white flowers. The Tectona grandis is the biggest of the three measuring up to a height of 115 feet. Its leaves are simple and its flowers are white.
The wood of the Tectona grandis is used in ship building, railways, furniture, cabinet making and various other commercial purposes. Dahat teak is not an important timber wood but is used locally for fuel and construction. Philippine teak is used for house posts and general construction but is not an important timber wood either. Both the Dahat and Philippine teaks have potential to be used for teak breeding but further research needs to be done.
- All three species of teak trees are in need of conservation. Natural forests of Tectona grandis have decreased in the last 50 years with the forests that remain threatened by illegal logging and other types of forest destruction. Only 4,300 living specimens of Philippine teak remain and the number of Dahat specimens is not known but it is considered endangered. Official protective measures are non-existent for the Philippine and Dahat teaks.
