There are a number of racking setups and designs suited for a certain application. Storage racks are typically divided into low-density, high-selectivity, and low-selectivity, high-density applications.

Racking with high selectivity and low-density is double deep, careful, as well as extremely narrow aisle racking systems. High-density applications are drive-in, push-back, and pallet circulation. Special systems are likewise possible which are essentially alterations of the previous configurations.
- Selective Racking: Selective pallet racking is defined by having a high SKU count but provides the lowest storage thickness. Standard discerning pallet racking can be imagined as huge shelves that have storage space for a single row of products. The racks can be set up back-to-back to improve storage thickness. It has reduced storage space density as a result of the space taken in by the aisles. This type is primarily seen in basic materials warehouses, components storage areas, and distribution centers where there are many distinct kinds of items with reduced volume. Selective pallet racking can be combined with various other kinds to fit SKUs with high volumes. Other buildings of discerning racking are its versatility in between FIFO as well as LIFO inventory monitoring, access for cleaning, the operability of standard forklifts, as well as stock audit, as well as easy building enabling easy reconfiguration. Selective racking has various styles of frame and beam of light links that are split right into slotted or teardrop racks.
- Drop Racks: Teardrop racking is a type of selective racking that has customized framework and beam accessories that can be reconfigured and broadened conveniently without using device tools. Upside-down teardrop-shaped openings are punched along the upright structures where pins connected to the beams are inserted. As the pin falls under the conical opening, rubbing safeguards it in place without needing additional fasteners. This link has adequate strength to be similar to long-term joints. Adding heavier tons triggers more rubbing to repair the beam of light in position. Cable decks are placed above the beams that become racks for the pallets. Appurtenances such as pallet sustains, ties, bars, as well as supports are included in more reinforcing the structure. Teardrop pallet racks are normally created by roll developing where metal sheets are cold-rolled into rectangle-shaped structures as well as beams of lights.
- Slotted Racks: These are in some cases referred to as architectural racks. Rather than utilizing upside-down teardrop-shaped openings, slotted racks have a pair of rectangular openings grated along with the upright framework. Attachment in between the structure and the beam of light can be by hooks extending from the beam of light or by screws. The main advantage of utilizing slotted racks over teardrop is its greater longevity as well as strength. Slotted racks are manufactured from hot-rolled architectural metal creating them more robust compared to teardrop racks. A greater gauge of sheet steel is utilized to allow a higher load-bearing capability. The drawback of utilizing slotted racks is their higher price, as well as weight.
- Double Deep Pallet Racking: This is an adjustment of the typical careful racking were as opposed to using single pallet rows, two rows are utilized per pallet rack. This raises the storage space capability of a selective racking by 40-60%. This also presents the advantages seen from the standard careful racking. To operate under FIFO stock administration, the surrounding rows need to have the same SKU. This increases the storage space density, but selectivity is reduced. The major disadvantage of utilizing this system is the requirement for specialized forklifts or typical forklifts with double deep handling add-ons. This brings about greater operating costs as well as needs well-trained drivers.
- Really Narrow Aisle, or VNA Racking: The principle of this pallet racking is to further enhance area use of a conventional careful while keeping 100% selectivity. This is done using loading pallets by a fork vehicle capable of side stocking. This removes added room meant for maneuvering a forklift. The aisle room can be reduced by up to 40%. A drawback for this type is the demand for two sets of devices for packing as well as discharging. One is a side-loading fork vehicle, as well as the various other a typical forklift for moving items from the palletizing station to the staging area.
