A pallet rack, also referre to as “pallet racking,” is for stocking inventory that sits on pallets (or “skids”) that are stored in horizontal rows with multiple levels; pallet racks allow warehouse inventory to be stored more efficiently (called maximum storage density). The pallet racks link together to create a pallet rack system. Forklift trucks are usually required to place the loaded pallets onto the racks for storage because of their size and weight. Pallet racks are essential and ubiquitous to modern warehouses, retail centers, and other facilities.
