Shorea laevis
Bangkirai (Shorea laevis) is a medium-hardness wood balancing workability and wear resistance, with a Janka hardness of 852 lbf (3790 N) and a density of about 0.85 g/cm³. It originates from se asia and pacific.
With radial shrinkage of 3.8% and tangential shrinkage of 7% (a T/R ratio of 1.84), it is reasonably stable with normal seasonal movement. Its fiber saturation point is around 26%, below which the wood begins to shrink and move as it dries.
