The Standard Malaysian Name for the timber of Duabanga spp. (Sonneratiaceae). Vernacular names applied include berembang bukit (Peninsular Malaysia), magas (Sabah), sawih (Sarawak) and tagahas (Sabah). There are only two species in Malaysia, viz. D. grandiflora (occurring only in Peninsular Malaysia) and D. moluccana (occurring only in Sabah and Sarawak). The sapwood is lighter in colour and not sharply defined from the heartwood, which is light red-brown.
Also known as Dem chhoeuter and Dlom chloeu ter (Cambodia); Lampati (India); Benuang laki, Gayawas hutan and Kalanggo (Indonesia); Ling ngo, Mai lin ngo, Phay, Sa phay and Ten (Laos); Lampati and Myaukngo (Myanmar); Banderbola (Pakistan); Duabanga (Papua New Guinea); Loktob (Philippines); Lamphaen, Lamphu-pa and Tum ten (Thailand); and Phay (Vietnam).
The timber is soft and light with a density of 385-465 kg/m3 air dry.
The timber is non-durable.
It is difficult to treat with preservatives.
Texture is coarse but even, with interlocked grain.
The timber is reported to be fairly strong and falls into Strength Group C (Burgess, 1958).
It is reported to be easy to saw and work.
The timber is reputed to season well without serious degrade.
Shrinkage is very high, with radial shrinkage averaging 3.9% and tangential shrinkage averaging 6.6%.
The timber is not used to any extent presently but should be suitable for general planking, packing boxes and crates, shuttering and plywood. The trees are reputed to grow very rapidly and this timber may be a source of short-fibred pulp for the manufacture of paper.
