| Selective Pallet Rack | 500–5,000 kg per beam level | 2–12 m | 100% direct access | Moderate | General warehouses, mixed-SKU inventory, high stock rotation | Flexible beam adjustment, easy forklift access, suitable for many pallet sizes | Requires wider aisles than high-density systems; capacity must be checked against beam and upright specifications |
| Drive-In Rack | 500–1,500 kg per pallet position | 3–10 m | Limited access | High | Cold storage and large quantities of the same SKU using last-in, first-out rotation | Reduces aisles and increases pallet density compared with selective rack | Requires compatible pallets and careful forklift operation; lower selectivity and higher impact risk |
| Push-Back Rack | 500–1,500 kg per pallet position | 3–10 m | Front access | High | Medium- to high-density storage with multiple pallets per SKU and last-in, first-out rotation | Stores several pallets deep while allowing loading and retrieval from the same aisle | More expensive than selective rack; pallet dimensions, weight, and trolley compatibility are important |
| Pallet Flow Rack | 500–1,500 kg per pallet position | 3–10 m | First-in, first-out | High | Perishable goods, food distribution, pharmaceuticals, and products requiring FIFO rotation | Gravity rollers automatically move pallets from the loading side to the picking side | Needs level floors and regular roller maintenance; generally costs more than static pallet rack |
| Cantilever Rack | 250–2,500 kg per arm | 2–8 m | Open front access | Moderate | Long, bulky, or irregular products such as pipes, timber, profiles, panels, and carpet rolls | No front columns obstruct the load; arm levels can be adjusted for different product lengths | Requires a stable, level floor and sufficient aisle clearance for long-load handling equipment |
| Carton Flow Rack | 50–250 kg per shelf or lane | 1.5–3 m | First-in, first-out | High for small items | Piece-picking operations, e-commerce fulfillment, spare parts, and fast-moving cartons | Separates replenishment from picking and supports efficient order picking | Best for standardized cartons or totes; roller lanes need correct pitch and load distribution |
| Mobile Rack | 500–3,000 kg per level | 2–10 m | One movable aisle | Very high | Cold rooms, archives, compact storage areas, and facilities where floor space is expensive | Eliminates most fixed aisles while maintaining direct access to stored loads | Higher purchase and installation cost; requires floor rails, safety controls, and dependable power or drive systems |
