Block

Upper deck is supported with a rectangular, square or cylindrical spacers. Block pallets may be required for heavier loads.

Skid

Wooden Pallet Deck BoardsDeck Boards

Multiple boards placed perpendicular to stringer forming both the top and bottom of the pallet and sometimes the top only.

Wood Pallet SpanSpan

Distance between deck board supports, either stringers or block.

Wood Pallet HeightOverall Height

Vertical span between the floor and top side of the top deck.

Wood Pallet LengthLength

Measurement of the stringer direction.

Wood Pallet LeadsLeads

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.

Wood Pallet WingWing

The top only (single wing) or both top and bottom boards (double wing) overhang the outer stringers. Usually used for heavier weights such as cement block.
