Light red meranti
Shorea spp. (lauan-meranti group)
Light red meranti measures 460 lbf on the Janka scale, about 36% as hard as northern red oak.
- Of the three merantis in the handbook, none is softer or lighter, and none bends more easily, shrinks more across the face or has a T/R ratio closer to 1.
- Of the 13 woods from Asia and Oceania in the tables, none is softer, lighter or weaker in bending, and none bends more easily.
- Drying barely changes its hardness: from 440 lbf green, it gains only 5% by 12% moisture, against a median of 31%.
- Its bending strength is 43% below the median for imported woods.
