Surian Batu


The Standard Malaysian Name for the timber of Chukrasia tabularis (Meliaceae). Vernacular names applied include cherana puteh (Peninsular Malaysia), repoh (Peninsular Malaysia), suntang (Peninsular Malaysia) and suntang puteh (Peninsular Malaysia). This is a monotypic timber. The sapwood is light yellow-brown or pink-brown and is moderately sharply or sharply defined from the heartwood, which is light red-brown or red, darkening to dark walnut-brown on exposure.

Also known as Voryong (Cambodia); Chickrassy and Chittagong wood (India); Mai nyom hin, Nhom, Nhom hin and Nhom khao (Laos); Chickrassy, Chikrasy, Tawyinma and Yinma (Myanmar); Chickrassy (Pakistan); Hulanhik (Sri Lanka); and Siet-Ka and Yom-Hin (Thailand).


The timber is moderately hard and moderately heavy to heavy with a density of 625-880 kg/m3 air dry.


The timber is moderately durable.


Texture is moderately fine and uneven, due to the conspicuous layers of parenchyma. Grain is interlocked and sometimes wavy.


The timber falls into Strength Group (SG) 3 (MS 544:Part 2:2001).


It is difficult to very difficult to resaw and cross-cut but planes easily and produces a moderately smooth finish.


The timber seasons fairly rapidly without any form of degrade. 13 mm thick boards take approximately 1.5 months to air dry, while 38 mm thick boards take 2.5 months.


Shrinkage is rather low, with radial shrinkage averaging 1.3% and tangential shrinkage averaging 1.7%.


The timber is equivalent to the famous "Indian wood"- chikrassy, which is highly prized as a high-class cabinet wood. The timber is suitable for interior finishing, panelling, mouldings, fancy furniture, plywood, door and window frames and sills, decking, flooring, staircase (balustrade, handrail and sprandrel framing), posts, beams, joists, rafters, joinery and ornamental items. The timber is also suitable for heavy and medium construction under cover.
