Pallet flow rack, also known as "gravity flow", is a FIFO (first in, first out) dynamic storage system. Pallet flow rack makes it possible to achieve high density storage while maintaining a FIFO retrieval order and product handling efficiency.
Gravity flow pallet racking maximizes actual storage space by minimizing aisles. Gravity pallet flow systems can be designed to hold up to 20 pallets deep in one lane, and allow for quick and efficient inventory turnover.
