The pallet rack is constructed so that it uses storage space effectively, increases the capacity of warehouse storage areas, and contributes to the clear organization of the material and goods stored. Generally, pallet rack construction is used for storing pallets with material directly on the rack's support beams or on its crossbeams. Barrels, rolls of material, and bundles of sheet metal or boards are stored on specialized crossbeams. Smaller-scale materials or boxes are stored on the decking of the pallet rack's bay. The decking can be manufactured from particle board in various thicknesses, steel grating, panels, etc. The racking quote is provided for the customer according to their requirements. It is common to have single row pallet racking around the perimeter of the warehouse and double row racking in the middle. The aisle width between the racks is determined by the type of forklift that the customer will be using in the warehouse.
