The common Malaysian name for the timber of Pterygota spp. (Sterculiaceae). Vernacular names applied include kangsar (Peninsular Malaysia), melebu (Sarawak) and menuang (Peninsular Malaysia). Major species include P. alata and P. horsfieldii. The sapwood is not differentiated from the heartwood, which is straw-coloured to light brown.
Also known as Narikel (India); and White tulip oak (Papua New Guinea).
The timber is moderately hard and moderately heavy with a density of 575-640 kg/m3 air dry.
The timber is non-durable under exposed conditions, being susceptible to both fungal and insect attacks.
Texture is moderately coarse and uneven due to the presence of abundant parenchyma. Grain is straight to shallowly interlocked.
The timber falls into Strength Group C (Burgess, 1958) or SG6 (MS 544:Part 2:2001).
It is easy to resaw and cross-cut. Planing is easy and the planed surface is smooth.
The timber is suitable for light and temporary construction, packing boxes and crates, pallets, plywood, ladies' shoe heels and perhaps as a source of short-fibred pulp.
