BLOCK

Rectangular, square or cylindrical deck spacer, often identified by its location within the pallet as corner block, end block, edge block, inner block, center or middle block

BOTTOM DECK

Assembly of deckboards comprising the lower, load bearing surface of the pallet

BLOCK PALLET

A type of pallet with blocks between the pallet decks or beneath the top deck. Alternative to a Stringer Pallet

QUALITY

Consistent performance of a uniform product meeting the customer’s needs for economy and function

PARTIAL FOUR-WAY STRINGER PALLET

A pallet with notched stringers. Allows for forklift access on 4 sides, but pallet jack access only on 2 sides. (See Four-Way Block Pallet for full 4 sided pallet jack access)

PALLET-DECK PALLET

Pallet constructed with composite or structural panel deck or decks

PALLET JACK

Hand-propelled wheeled platform, equipped with a lifting device for moving palletized unit loads

PALLET SIZE

Overall dimension of a pallet stated in terms of length followed by width and height; for example, a 48′′ x 40′′ pallet is 48′′

PALLET DESIGN SYSTEM (PDS)

Reliability-based computer-aided design (CAD) program, for determining the safe load carrying capacity, performance, life and economy of wooden pallets

PALLET

A portable, horizontal, rigid platform used as a base for assembling, storing, stacking, handling and transporting goods as a unit load, often equipped with a superstructuret

NOTCHED STRINGER

A stringer with two notches spaced for fork-tine entry, (partial four-way entry)

NOTCH

Cutout in lower portion of the stringer to allow entry for the fork tine, usually 9′′ in length, 1 1/2′′ in depth

NON-REVERSIBLE PALLET

A pallet with bottom deckboard configuration different from top deck

NATIONAL WOODEN PALLET AND CONTAINER ASSOCIATION

A national association with the goal of promoting the design, manufacture, distribution, recycling, and sale of pallets, containers, and reels

LENGTH

Refers to the stringer or stringerboard (in block pallets) length; also refers to the first dimension given to describe a pallet i.e., 48′′ x 40′′, where 48′′ is the pallet stringer/stringerboard lengtht

INNER DECKBOARD

Any deckboard located between the end deckboards

HARDWOOD

Wood from broad-leaved species of trees (not necessarily hard or dense). Some hardwood species are not as strong as some softwood species

FOUR-WAY BLOCK PALLET

A pallet with openings at both pallet ends and along pallet sides sufficient to admit hand-pallet jacks; full four-way entry pallet

FLUSH PALLET

A pallet with deckboards flush with the stringers, stringer-boards or blocks along the sides of the pallet

FASTENER

A mechanical device for joining pallet components such as nails, staples, bolts or screws

DOUBLE-WING PALLET

A pallet with top and bottom deckboards extending beyond the edges of the stringers or stringerboards

DECKBOARD SPAN

Distance between deckboard supports (stringers, stringerboards or blocks)

DECKBOARD SPACING

Distance between adjacent deckboards

DECKBOARD

Element or component of a pallet deck, oriented perpendicular to the stringer or stringerboard

DECK MAT

Assembly of deckboards and stringerboards, forming the deck of a block pallet

DECK

One or more boards or panels comprising the top or bottom surface of the pallet

CHAMFERED DECKBOARD

A deckboard with edges of one or two faces beveled, either along the full or specified length of board or between the stringers of blocks, allowing easier entry of pallet jack wheels

CAD

Computer-aided-design software that allows the design of the “right” pallet at the best value;

see Pallet Design System (PDS)

RACKED ACROSS DECKBOARDS (RAD)

Output from PDS program describing the maximum load carrying capacity and deflection of a pallet where the rack frame supports the pallet only at the ends of the deckboards

RACKED ACROSS STRINGERS (RAS)

Output from the PDS program describing the maximum load carrying capacity and deflection of a pallet where the rack frame supports the pallet only at the ends of the stringers or stringer boards

REVERSIBLE PALLET

A pallet with identical top and bottom decks

SINGLE-WING PALLET

A pallet with the top deckboards extending beyond the edges of the stringers or stringer-boards with the bottom deckboards flush (if present)

SKID

A pallet having no bottom deck

SOFTWOOD

Wood from coniferous or needle-bearing trees (not necessarily soft or low density). Some softwood species are stronger than some hardwood species

SOLID DECK PALLET

A pallet constructed with no spacing between deckboards

STRAPPING

Thin flat bands used to secure load to pallet

STRINGER

Continuous, longitudinal, solid or notched beam-component of the pallet used to support deck components, often identified by location as the outside or center stringer. Alternative to a Block Pallet

STRINGERBOARD

In block pallets, continuous, solid board member extending for the full length of the pallet perpendicular to deckboard members and placed between deckboards and blocks

TWO-WAY ENTRY PALLET

A pallet with unnotched solid stringers allowing entry only from the ends

UNIT LOAD

Assembly of goods on a pallet for handling, moving, storing and stacking as a single entity

WING

Overhang of deckboard end from outside edge of stringer or stringer-board. Can be associated with top deck, bottom deck or both
