Definition
A pallet bottom deck configuration in which boards run along the outer perimeter of the pallet, forming a continuous frame on the bottom. Perimeter base pallets provide excellent stability on conveyor systems because the continuous outer boards create a flat, even running surface. This design is commonly found in block pallets and is preferred for automated distribution centers where conveyor compatibility is essential.

Bottom Deck
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.
Block Pallet
A pallet constructed using blocks of solid wood or composite material between the top and bottom deck boards, typically with nine blocks arranged in a 3x3 pattern. Block pallets offer true four-way entry, allowing forklifts and pallet jacks to access the pallet from all four sides. They are generally stronger and more durable than stringer pallets, making them common in pooling programs and heavy-duty applications.
Conveyor Compatible
A pallet design that meets the dimensional, weight, and structural requirements for reliable automated conveyor handling. Conveyor-compatible pallets must have consistent dimensions, flat bottom deck surfaces free of protruding nails, and sufficient rigidity to travel smoothly on roller or chain conveyors. Bottom board spacing and orientation are particularly critical, as gaps or misaligned boards can catch on conveyor rollers and cause jams.
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.
