A variant on standard adjustable beam racking, Union’s Double-deep pallet racking, as the name implies, allows pallets to be stored two deep but still accessible from the same aisle. By reducing the number of access aisles and using the space saved to accommodates additional racking, a Double –deep configuration provides a highly space-efficient storage system. Although the speed of access to all of the pallet position is restricted, with an efficient stock management system this can easily be compensated for to take advantage of the benefits of more storage space.
