Pallet Flow Rack
Pallet flow rack is a type of pallet storage rack used for high density storage and First-In-First Out (FIFO). Pallet flow makes it possible to achieve high density storage while maintaining FIFO retrieval order and handling efficiency. This type of gravity flow pallet system maximizes storage space by reducing aisles.
Pallet flow systems can be designed to hold 2 to 20 pallets deep or more in one lane, and allow for quick and efficient inventory turnover. Customization is key in pallet flow rack systems, and manufacturers offer multiple types of rollers to meet the demands of individual users’ pallets and products. Most manufacturers can even customize their pallet flow with speed controllers that are uniquely designed for the user’s wide range of pallet weights.

How Pallet Flow Racks Work
Pallet flow rack systems are designed to be loaded into the storage lane from a replenishment aisle and gravity flow, in order, to a pick aisle. The pallets are first placed onto rollers upon which the pallets easily flow towards the front of the rack system. Once they’ve glided to the front of the system, pallets rest on pallet stops until they’re unloaded. As pallets are removed or unloaded from the system, each of the pallets that were behind them “flow” into the next position via gravity. Pallet speed is controlled by the speed controllers engineered into the system.
Common Questions Regarding Pallet Flow Systems
Lead times for pallet flow projects are similar to other engineered rack systems, with lead time periods generally in the 6 to 12 week range. Lead times can be influenced by the approval process and high manufacturing demand at time order is placed.
The pitch of a pallet flow lane can vary from system to system. That being said, the most common pitch given to pallet flow lanes is 3/8″ to 1/2″ per linear foot. To illustrate this, imagine a pallet flow lane that is 20’ long. If the pitch is 1/2″ per linear foot, the load end of the lane will be 10″ taller than the picking end. This pitch allows the pallet to “flow” without assistance from the back end of the lane to the front.
