Definition
The lower surface of a pallet, consisting of boards that run along the underside and rest on the floor or racking surface. Bottom deck boards provide structural support, distribute the load across floor surfaces, and protect products on pallets stacked below. The configuration and number of bottom deck boards directly affect a pallet's stability, rackability, and compatibility with conveyor systems.

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.
Top Cap
A flat sheet of corrugated board, plastic, or plywood placed on top of a palletized load before wrapping or strapping. Top caps distribute downward pressure from stacked loads, protect the top layer of products from dust and moisture, and provide a stable surface for stacking additional pallets on top. They are an inexpensive way to increase the stacking strength of a unit load and are widely used in distribution centers and warehouses.
Pallet
A flat transport structure, typically made of wood, that supports goods in a stable fashion while being lifted by a forklift, pallet jack, or other jacking device. Pallets are the foundation of modern material handling and logistics, enabling efficient storage, stacking, and transportation of goods. The most common pallet size in North America is the 48x40 inch GMA pallet.
Double Face
A pallet that has deck boards on both its top and bottom surfaces, providing load-bearing surfaces on each side. Double-face pallets offer improved stability in stacking and racking applications compared to single-face designs. They can be further classified as reversible (usable with either side up) or non-reversible (designed with a specific top and bottom orientation). Double-face construction is the standard for most warehouse and shipping pallets.
