Definition
A pallet deck constructed with no gaps between the deck boards or using a single sheet of panel material, providing a continuous flat surface. Solid-deck pallets are required for handling small items that could fall through gaps, for powdered or granular products in bags, and for clean-room and food-processing environments. They offer maximum load-bearing surface area but are heavier, more expensive, and may trap moisture compared to spaced-board decks.

Panel Deck
A pallet deck constructed from a single sheet of plywood, OSB, or other panel material rather than individual deck boards. Panel decks provide a smooth, continuous load-bearing surface with no gaps between boards, making them ideal for small items, bags, and products with irregular bottoms that could fall through spaced deck boards. Panel-deck pallets are common in export and display applications.
Deck Board
The flat boards that form the top and bottom surfaces of a pallet. Top deck boards provide the platform on which goods are placed, while bottom deck boards (also called bottom boards) provide stability and allow the pallet to be stored on flat surfaces. Deck board thickness, width, and spacing directly affect a pallet's load capacity and suitability for different applications.
Load-Bearing Surface
The total area of a pallet's top deck that is in direct contact with and supports the goods placed on it. A larger load-bearing surface distributes weight more evenly, reducing point loads and the risk of product damage. Solid-deck pallets provide 100% load-bearing surface, while pallets with spaced deck boards provide less. The load-bearing surface percentage is an important specification for products with fragile bottoms or small footprints.
Point Load
A concentrated force applied to a small area of a pallet deck, as opposed to a uniformly distributed load spread across the entire surface. Point loads are caused by heavy items with small footprints, such as machinery legs, steel drums, or stacked pails. Pallets subjected to point loads require thicker deck boards, closer board spacing, or solid deck panels to prevent localized failure. Point load capacity is an important but often overlooked pallet specification.
