Double deep pallet racking maximizes storage volume and decrease the aisles. By storing pallets two deep, could achieve higher storage density than selective pallet racking.

Double deep pallet racking must use with special forklifts prepared for this type of system, equipped with a forklift with double stretchable arms, and the aisle depth should be around 3.3meters. In order to increase the stock rotation, should consider storing the rear shelves first, and then storing the front shelves when storing. Lower level stock is required to be stored on beams just above the ground adding to rack safety and stability.
