| Selective Pallet Rack | Approximately 500–4,500 kg per pallet position, subject to design | High accessibility | Many SKUs with mixed pallet sizes and frequent picking | Direct access to every pallet; simple stock rotation; easy to reconfigure | Requires wider operating aisles than some high-density systems; verify floor loading and rack-upright capacity | Distribution centers and general warehouses with broad SKU variety |
| Carton Flow Rack | Usually approximately 50–250 kg per carton lane level | High picking density | Small cartons, totes, and fast-moving piece-pick inventory | Gravity-fed FIFO flow; ergonomic replenishment and picking; good order accuracy | Needs compatible carton dimensions, lane pitch, replenishment access, and roller maintenance | E-commerce fulfillment, spare parts, and order-consolidation areas |
| Longspan Shelving | Approximately 150–800 kg per shelf level, depending on span and decking | Flexible | Loose parts, containers, cartons, and medium-sized items | Hand-loaded; adaptable shelf heights; useful for irregular product sizes | Confirm shelf deflection limits, load distribution, access stairs, and edge protection on the mezzanine | Maintenance stores, light assembly, archives, and component storage |
| Double-Deep Pallet Rack | Approximately 500–4,500 kg per pallet position, subject to design | Very high density | Several pallets of the same SKU or batch | Increases storage density while retaining forklift access from the aisle | Requires reach equipment, compatible pallet quality, inventory discipline, and reduced selectivity | Buffer storage and warehouses with medium SKU variety and repeat pallet loads |
| Mobile Pallet Rack | Approximately 500–4,500 kg per pallet position, subject to design | Maximum density | Low-to-medium throughput pallet inventory | Uses movable aisles to reduce redundant aisle space; can significantly increase cubic utilization | Higher capital cost; requires level floors, controls, safety interlocks, and careful traffic planning | Cold storage, document storage, and facilities where floor area is expensive |
| Cantilever Rack | Approximately 250–2,500 kg per arm or level, subject to design | Long-load optimized | Pipe, timber, profiles, panels, and other long or irregular products | Open front design supports simple loading; adjustable arms accommodate different lengths | Check arm deflection, column stability, product overhang, aisle width, and anti-roll protection | Building materials, fabrication shops, and industrial component storage |
| Push-Back Rack | Approximately 500–4,500 kg per pallet position, subject to design | High-density LIFO | Batch-based pallets with limited SKU variety | Stores multiple pallets deep without drive-in entry; fast loading and unloading from the aisle | Usually follows LIFO; confirm pallet compatibility, lane depth, slope, and forklift operating requirements | Seasonal goods, reserve inventory, and products with stable batch control |
