Wood Physical Properties
Drying Defects
Ease of Drying: The rate of shrinkage is medium. Drying is easy to moderately difficult. Drying Defects: Some drying defects such as end-checking, splitting, cupping and springing may occur. Since the timber tends to warp and twist weighting down of stacks during air drying is recommended. Kiln Schedules: The rate of drying is rather similar to light red meranti. Mild kiln schedules are requiring in drying.
Recommended Dry Kiln Schedule
FR-8
