Usages
Chengal is a very durable and heavy timber and is therefore suitable for many heavy-duty purposes. It was the standard timber for durable heavy construction in Peninsular Malaysia and can be applied both indoors and outdoors. It is suitable for railway sleepers, piles, bridges, telegraph and power-line poles, vats, casks, tanks and frameworks, especially for wooden houses but even for e.g. lorries and buses. Indoors it is used for flooring (medium and heavy duty) and joinery. Chengal has been used in constructing wharves, ships and boats both in fresh and salt water conditions, with good results. Despite its hardness it is used for carving; carving is comparatively easy, especially when the wood is fresh.
Good-quality resin, known in Peninsular Malaysia as "damar penak", can be obtained by wounding the tree. It has been used only on a limited scale in the manufacture of certain classes of varnish.
