In a plywood panel, the grain direction in adjacent veneers is at right angles to each other, referred to as cross-graining of veneers. Cross-graining equalizes the panel strength in the two principal directions of the panel. Does it mean that a plywood panel (typical size is 4 ft × 8 ft) is equal in strength in its long and short directions?
What will be an ideal response?
No. the plywood panel is stronger in its long direction (8 ft direction) because the grain direction in the face (top and bottom) veneers is oriented along the long direction.
