Definition
The practice of storing loaded pallets on elevated warehouse racking systems (pallet racks). Racking places unique demands on pallet strength because the pallet spans across the rack beams with its load weight concentrated on the supported edges rather than distributed across a flat floor. A pallet's racking capacity is typically its most demanding load rating, and not all pallets are suitable for racking. Rackable pallets must be specifically designed and rated for this application.

Static Load
The maximum weight a pallet can safely support when resting on a flat, level surface without being moved. Static load capacity is the highest load rating for most pallets because the weight is evenly distributed across the bottom deck. A typical GMA pallet has a static load capacity of 2,500 to 5,000 pounds. Static load ratings are relevant for floor storage and long-term warehousing applications.
Dynamic Load
The maximum weight a pallet can safely support while being moved by a forklift or pallet jack. Dynamic load capacity is lower than static load capacity because the pallet is subject to additional stresses from acceleration, deceleration, turning, and uneven floor surfaces during movement. A typical GMA pallet has a dynamic load capacity of 2,000 to 2,800 pounds. Dynamic load ratings are critical for transportation and material handling operations.
Rackable Pallet
A pallet specifically designed and rated for use in pallet racking systems, where the pallet spans across two rack beams with its load suspended above the floor. Rackable pallets must have sufficient bending strength to support their rated load without excessive deflection (sagging) across the span. This is the most demanding application for a pallet, and rackable load capacity is always lower than static or dynamic load ratings. Typical rackable capacity for a GMA pallet ranges from 1,500 to 2,500 pounds.
Warehouse Pallet
A general-purpose pallet designed for use within warehouse and distribution center environments, optimized for racking, forklift handling, and conveyor compatibility. Warehouse pallets prioritize dimensional consistency, rackability, and durability for multiple use cycles. They are typically held to tighter quality standards than pallets used for one-way shipping, as they must interface reliably with automated warehouse systems and maintain performance through many handling cycles.
