Teak is one of the most well-known woods in the world. It owes its excellent reputation to its unique combination of the best dimensional stability and highest resistance class.

Since the wood only has a very low risk of warping, the risk of cracks and splinters forming is lower than with any other wood in the first durability class. Therefore, it is considered one of the best decking wood. But it is also used for furniture making, shipbuilding, parquet flooring and cutting boards.

Teak - The kingwood

The natural distribution area of ​​teak is in south-east Asia and India. The main teak producers are Indonesia and Myanmar (Burma). In the late XNUMXs and early XNUMXs, due to the high global demand for teak, teak plantations began to be established in the tropical regions of Central America, South America and Africa. The substitutes of teak are iroko, nutka mock cyxpress (yellow cedar) and Indian padauk.

The growth zones are clearly visible in teak. The heartwood is brown to yellow (golden brown) with streaks, with the sapwood being a distinct contrast to the heartwood due to its lighter colour. The surface of teak is slightly greasy.

The teak tree

A teak tree can reach a height of 25 - 35 m with a branch-free trunk length of 10 - 20 m. The average DBH of teak is 0,5 - 1m. The maximum BHD can be 1,5 m. The height, the BHD and the quality of the teak wood are determined by the nature of the soil (nutrient content) and the climatic conditions (tropical).

In Burma there are trees with a height of 40 - 45 m with a DBH of 1,8 - 2,5 m. The natural teak deposits in Burma are considered to be the most valuable, most desirable and highest quality stocks in the world. Due to the high demand, especially from India as the largest importer of teak and producer of teak products worldwide, biodiversity and the occurrence of natural teak resources are endangered.

Teak from plantations

As an alternative to the naturally grown teak stocks, teak from plantations is increasingly being offered on the world market. As mentioned above, plantations were planted in the tropical regions of Central America, South America and Africa. The harvest age of this plantation teak should be from the age of 25 - 40 years. Scientific studies have shown that it is only from this age that enough extract substances are formed to ensure the durability of teak products. Trunks that are larger than 1 m in diameter (DHD) should no longer be harvested, as they are often rotted inside.

Because of its good properties, teak is referred to as "the king of wood species". As already described in the previous paragraph, the oil extracts that teak develops more and more with age play a decisive role. The density of teak is between 750 kg/m³ and can reach a maximum of 1000 kg/m³.

Tectona grandis has a hardness of 4450 N according to Janka. The dimensional stability of teak at a wood moisture content of 12% is very good. Teak has a low radial and tangential shrinkage rate of 1,0% radial and 1,6% tangential.

The relationship between stress and strain, which causes the force to act on the elasticity of the wood, is given for teak with a MOE of 10,000 N/mm2 and the flexural and compressive strength until fracture, the so-called MOR, is given with 101 N/mm2. Teak has one durability class according to DIN-EN 350-2 of "Class 1". For plantation wood worldwide, the durability class can vary between class 1 - class 3.

teak from BioMaderas

The teak from BioMaderas achieves a durability class of class 1, as the teak trees are only harvested sustainably from the age of more than 30 years, after the tree has formed the most important extracts to increase durability.

The possible uses of teak are very diverse due to its many positive properties, such as high durability, high dimensional stability, high strength properties and of course its decorative properties. That is why teak is very popular for garden furniture, boat decks and patio decking.
