Double deep pallet racking is a high-density storage solution designed to maximize warehouse space utilization. It allows for the storage of two pallets deep per rack, effectively doubling the storage capacity compared to traditional selective racking systems. This system is ideal for operations with a large quantity of the same SKU and works on a first-in, last-out (FILO) principle, where the pallets stored last are accessed first. While it requires specialized forklifts with extended reach, double deep racking optimizes storage density by reducing aisle space. This makes it suitable for products with lower turnover rates and enables efficient use of warehouse space while maintaining a relatively high level of selectivity.
