a shipping pallet is constructed of multiple laminations of corrugated sheet material , with specific construction details providing advantages in strength and trueness of the completed pallet , and further advantages in the reduction of tooling and labor costs . the stringers or runners , deck boards , and top and bottom sheets may be sawn from stacks of plural laminations , thus precluding any requirement for costly dies and intensive labor . asymmetrical corrugated sheets may be used , with one side having a different weight than the other . by laminating two such sheets together with like weighted sides in contact , the tendency of such sheets to curve or warp due to the difference in side thickness is substantially eliminated . different orientations of the corrugations or flutes of the sheets during lamination and assembly of the pallet , provide advantages in strength for specific applications . the deck boards and stringers may be notched so as to interlock with one another , thus providing additional strength and durability . the pallet may be constructed of plural laminations of various corrugated sheet materials , such as paperboard or fiberboard , or plastic .
