Take a look at the benefits of Keruing timber and how to order, below.

What is Keruing Timber?

Keruing Timber comprises 70 similar species (from various areas in Malaysia/Sarawak/Sabah/Indonesia) which have variations of density and weight. Texture is moderately coarse and may have shallow interlocking grain. The colouring is not an issue as it is used for exterior constructions and will weather to silver-grey.

Keruing Timber is used for: Heavy Structural Use, Flooring, Lorry Beds, Wharf Decking and many more. Sizes we mainly stock are 50mm x 150mm sawn and 28mm x 140mm profiled Half-lap vehicle flooring, although some other sizes are available in limited quantities.



The Tree

Latin name Dipterocarpus spp, Dipterocarpus cornutus, Dipterocarpus costulatus, Dipterocarpus crinitus, Dipterocarpus sublamellatus, Dipterocarpus apterus, Dipterocarpus lowii, Dipterocarpus verrucosus, Dipterocarpus gracilis, Dipterocarpus acutangulus, Dipterocarpus grandiflorus, Dipterocarpus warburgii.

Also known as apitong, Sabah gurjun, yang, Malaysian keruing, Indonesian keruing, Sarawak keruing, kruen. 

The tree is evergreen and generally large, depending on locality, reaching heights of 25m to 45m and a diameter of 0.75m to 1.5m with a straight, cylindrical bole often clear of branches to 21 m above a small buttressed base.


The Timber

The sapwood is greyish-brown and distinct, and usually 50mm to 75mm wide. The heartwood varies from light red to reddish-brown or brown, darkening on exposure. The grain is usually straight but may be shallowly interlocked, and the texture is moderately coarse or coarse, but even. The timber contains an oleo-resin which exudes in a number of pieces especially on the end grain. The various species vary in weight from 640 kg/m³ to 960 kg/m³ but an average for the group is about 740 kg/m³ when dried.


Strength and Durability

Keruing generally compares with teak in most strength categories, but it is a little stiffer, and about 40 per cent more resistant to shock loads.

Keruing ia moderately durable, non-resistant to some termites and is resistant to preservative-treatments.


Physical Properties

The variations that exist between the different species and within species in respect of resin content, type of grain and hardness, affect the general ease of working, dulling of cutters and finishing properties. The timbers vary from hard to very hard in cutting across the grain, and whereas straight grained material is capable of clean, slightly fibrous finish in planing and moulding, quarter-sawn, or interlocked-grained material picks up during these operations unless cutting angles are reduced to 20°. Contains silica which has a blunting effect on tools.

The wood stains satisfactorily, but due to the resin, varnishing and polishing require a lot of care. It takes nails and screws reasonably well, but its gluing properties are variable. Normally sold air-dried. Some cupping may occur.

Keruing has high crushing strength and medium resistance to shock-loads. Exudes resin naturally in humid or warmer temperatures.
