Common Industry Terms


Block – rectangular, square, multisided, or cylindrical deck spacer, often identified by its location

within the pallet as corner block, end block, edge block, inner block, or center or middle block.


Block size – pallet member dimension, specified by width followed by height and length.


Deckboard – element or component of pallet top and bottom, perpendicular to stringers or


Deckboard size – specified by thickness followed by width and length.


Delamination – a visible separation in the plane of a panel or panel component. This may occur

in the panel manufacturing process, or in use due to rough handling. The latter may be caused by

impacting panel edges with a tine tip, and may or may not result in material being removed from

the panel component.


MIBANT Angle2 – fastener bend angle providing indication of (fastener) toughness and bending



Notch area – a region around stringer notches with special defect limitations (see Figure 5).

Pallet Design System© (PDS) Рa reliability-based computer-aided design (CAD) software for

wood stringer and block pallets.


Pallet length – pallet dimension between the extreme pallet ends, parallel to the stringers or top

stringerboards. For panel-deck block pallets without stringerboards, it is the top deck pallet

dimension parallel to the face grain for plywood (strong panel axis).


Pallet width – pallet dimension between the extreme pallet sides, parallel to and corresponding to

the length of the top deckboards. For panel deck block pallets without stringerboards, it is the

top deck panel dimension perpendicular to the face grain for plywood.


Pallet size – pallet dimension specified by stringer or stringerboard length, followed by top

deckboard length and overall pallet height. For panel deck block pallets, it is the length, width,

and overall pallet height.


Panel – a wood based structural panel, either plywood or oriented strand board (OSB).
