Boards at either end of the deck. Usually when leads are referred to they are wider than the inner boards for increasing structurally integrity. They will usually be 5.5 “wide and known as 6” lead boards.

Wood Pallet InnersInners

Boards in between lead boards. Spacing requirements will usually dictate the number of inner boards used. On average, the width of an inner board is usually 3.5”.

Wood Pallet SpacingSpacing

The spacing between the deck boards. Space is most critical part of the top decking It’s usually dictated by the need to increase total weight across the entire surface or to accommodate the size or shape of the load so that product cannot tip or fall into the spacing. Lighter weight product with large foot prints can sometimes use fewer boards, thus saving money.

Wooden Pallet FlushFlush

A pallet with deck boards flush to the stringer or block. No overhang.

Wood Pallet PlugPlug

The repair board attached to a defective stringer to make it usable again. A plug is can run the full length of a stringer or only over a section of the stringer being repaired. The number of stringers repaired is used as part of the grading process in GMA pallets.
