2. Drive-In and Drive-Through Racking

Drive-in and drive-through racking systems are designed for high-density storage. These systems minimize the need for aisles by allowing forklifts to drive directly into the rack structure to load and unload pallets. Drive-in racking has only one access point, while drive-through racking has two, allowing for greater flexibility in inventory management. These systems are ideal for storing large quantities of similar items that do not require frequent rotation.

3. Push Back Racking

Push back racking systems use a series of nested carts that move along inclined rails. When a new pallet is loaded, it pushes the previous pallets back, and when a pallet is removed, the remaining pallets roll forward. This system allows for high-density storage and better space utilization, as multiple pallets can be stored on each level. It is well-suited for medium-turnover products.

4. Pallet Flow Racking

Pallet flow racking, also known as gravity flow racking, uses gravity to move pallets from the loading end to the picking end on inclined rollers. This system supports a first-in, first-out (FIFO) inventory management approach, making it ideal for perishable goods and items with expiration dates. Pallet flow racking maximizes storage density and ensures efficient product rotation.

5. Cantilever Racking

Cantilever racking is designed for storing long, bulky items such as pipes, lumber, and sheet materials. It features arms that extend from a central column, allowing for unobstructed storage of items of varying lengths. Cantilever racking systems are highly adaptable and can be adjusted to accommodate different load sizes and weights.

6. Mezzanine Racking

Mezzanine racking systems add an additional level of storage above existing racks, effectively doubling the available storage space without expanding the footprint of the facility. These systems are ideal for warehouses with high ceilings and can be equipped with stairs, lifts, and conveyor belts to facilitate easy access to stored items. Mezzanine racking is a cost-effective solution for increasing storage capacity.
