About Timber

Uses

Malaysian timbers have been used in a wide range of industrial and domestic applications, both locally as well as in major importing countries in Europe, the Middle East, the United States, Japan and Australia. However, in this broacher, it is intended to indicate only the major types of application of manufacture for which Malaysian timbers have been found to be particularly suitable and widely used, namely flooring, furniture, joinery, building and construction, plywood / veneer, railway sleepers, panelling and partitioning. Undoubtedly, with changing technologies and advances in research, further uses can be found for Malaysian timbers.

Colour

As wood is a product of nature, it is not unusual to find variations in its colour and figure appearance even among those that belong to the same species. It is this variations which somewhat makes them even more attractive. As there are limits to which natural colour may be reproduced in a photographic illustration, the publication of this brochure has not therefore been without problems. The colour of some of the species illustrated may be shade different from the natural colour of wood. The illustrations as a whole, however, are reasonably representative of the colour of the wood that has been used as samples.

Classification and density range of Timbers 

-Heavy Hardwoods

There are heavy or very heavy constructional timbers ranging in density from about 800kg/m3 to 1120 kg/m3 at 15 % moisture content. They are naturally durable as they contain within their tissue some toxic materials, e.g. alkaloids or other substances repellent to wood destroying agents and can therefore be safely used without preservative treatment even in positions exposed to fungus or termite activities the sapwood of these timbers however, is not durable.

 

-Medium Hardwoods

There are moderately heavy to heavy constructional timbers ranging in density from about 720 to 880 kg. per cu. m . at 15 per cent moisture content. Some of these timbers are heavy and strong enough to be classified as “Heavy Hardwoods” but under tropical conditions they lack sufficient natural durability when exposed to the weather or in contact with the ground unless they are properly treated with preservatives before use. Most of them however, are naturally durable in temperate countries where climatic conditions are less conducive to the activity of the wood destroying agents.

 

-Light Hardwoods

These include all the relatively light weight and soft timber which range in density from about 400 to 720 kg/m3 at 15 per cent moisture content. They are the ‘general utility’ timbers of Malaysia comparable with the general utility timbers in temperate climates; the letter however, are mainly softwoods (conifers).

In addition to general utility purpose many of these Light Hardwoods are excellent for high class joinery work, cabinet making, furniture, decorative panelling, etc. Although not naturally durable in tropical climate, some are quite durable in temperate regions. Provided that proper precautions are taken against attack by wood destroying agents, the Light Hardwoods as a whole make very satisfactory timbers for general construction even when used in tropical climates.


-Softwood

There are very few true softwoods of commercial significance in Malaysia. None are durable in the tropics. The main difference between the timber of Hardwoods and Softwoods (conifers) is the absence of vessels (pores) in softwoods.
