Redirack Adjustable Pallet Racking is one of the most widely used systems for storing palletised unit loads. It consists of upright frames and horizontal beams that interlock to form the racking structure. Within the rack each pallet is individually accessible. Pallet Racking arranged in a wide aisle pattern requires no specialised handling equipment. Arranged this way it gives high quality storage but may only utilise 40% of the floor space. However, fast throughput and ease of loading and unloading make this type of storage extremely popular.
