Racking systems consist of vertical uprights and horizontal beams that form shelves or pallet storage areas. They can be made from different materials, such as steel or aluminum, and can be designed in various configurations to suit different storage needs.

Pallet racks are the most common type of racking system and are used to store palletized items. They consist of horizontal beams that form pallet storage areas and vertical uprights that support the beams. Pallet racks can be designed with different beam and upright sizes to accommodate different pallet sizes and weights.
