Our recommendation: Tembusu is rarely felled locally and hence rarely found in sawmills of Singapore. Known for its hardness, Tembusu is commonly used as chopping boards and timber decking locally.

Due to lack of competition for sunlight, the Tembusu grown locally are seldom straight enough for large, straight planks to be harvested. Normally 200mm – 300mm width will be rare while sizes like 95mm x 20mm cross-sectional areas should easily be available.

These materials are generally good for outdoor decking or even timber cladding, which can last on average between 5-10 years with proper upkeep (without chemical treatment).

 

Common sizes available:

95mm x 20mm x 3ft – 6ft

300mm diameter x 40mm thickness (round slab)
