This document discusses different types of pallet designs. There are two main designs: block designs and stringer designs. Block designs use cylindrical posts to separate the top and bottom decks, while stringer designs use long runners along the full length. The document then defines various types of pallets including block, double-face, double-wing, flush, four-way stringer, non-reversible, reversible, single-wing, skid, solid deck, and two-way entry pallets.
