| Selective Pallet Racking | Individual pallets stored on adjustable beams with direct access to every pallet position. | 500–4,500 kg per level | 2,000–12,000 mm | 2,400–3,900 mm | Approximately 2,700–3,700 mm, depending on forklift type and pallet dimensions | General warehouses, distribution centers, spare-parts storage, and mixed-SKU inventory | High selectivity, flexible beam adjustment, easy stock rotation, and relatively simple installation |
| Heavy-Duty Pallet Racking | Large pallets or heavy loads stored on reinforced upright frames and load beams. | 1,000–5,000 kg per level | 3,000–12,000 mm | 2,700–4,200 mm | Approximately 3,000–4,000 mm | Metal products, machinery components, building materials, and industrial raw materials | High structural strength, suitable for heavy pallets, and adaptable to different load sizes |
| Drive-In Racking | Forklifts enter storage lanes to place pallets on continuous support rails, generally using a last-in, first-out method. | 500–1,500 kg per pallet position | 3,000–10,000 mm | Storage lane depth commonly 4–10 pallets | Reduced aisle count; forklift access is through the front of each lane | Cold storage, beverage warehouses, and high-volume products with few SKUs | High storage density, efficient use of floor space, and reduced number of operating aisles |
| Drive-Through Racking | Forklifts can enter from both ends of the storage lanes, supporting first-in, first-out operation when properly managed. | 500–1,500 kg per pallet position | 3,000–10,000 mm | Storage lane depth commonly 4–10 pallets | Access aisles are required on both sides of the rack block | High-volume inventory requiring loading and unloading from opposite sides | High density combined with better stock accessibility than single-sided drive-in systems |
| Double-Deep Pallet Racking | Two rows of pallets are positioned one behind another and handled with reach trucks or specialized equipment. | 500–1,500 kg per pallet position | 3,000–11,000 mm | 2,400–3,900 mm per row | Approximately 2,800–3,500 mm, depending on equipment | Warehouses with medium SKU variety and a need for higher density than selective racking | Greater pallet density and lower aisle-space ratio than standard selective racking |
| Very Narrow Aisle Racking | High-rise pallet rack installed in narrow aisles and operated with turret trucks or specialized narrow-aisle equipment. | 500–1,500 kg per level | 6,000–18,000 mm | 2,400–3,600 mm | Approximately 1,500–1,900 mm | High-bay warehouses where floor space is limited and pallet selectivity is important | High use of vertical space, good pallet access, and efficient floor-space utilization |
| Mobile Pallet Racking | Rack rows are mounted on motorized or mechanically assisted mobile bases that open only where access is needed. | 500–1,500 kg per level | 2,500–10,000 mm | 2,400–3,900 mm | One operating aisle can serve multiple movable rack rows | Cold rooms, archives, high-value inventory, and facilities with expensive floor space | Very high space utilization and direct access to stored goods when the required aisle is opened |
| Push-Back Racking | Pallets are loaded from the front and pushed backward on inclined rails or carts, generally using a last-in, first-out method. | 500–1,500 kg per pallet position | 3,000–10,000 mm | Storage lane depth commonly 2–6 pallets | Approximately 3,000–3,800 mm | Medium-turnover products, seasonal goods, and warehouses storing several pallets per SKU | Good density, faster loading and retrieval than drive-in systems, and no forklift entry into the lane |
| Pallet Flow Racking | Pallets move by gravity on roller tracks from the loading side toward the picking side, supporting first-in, first-out rotation. | 500–1,500 kg per pallet position | 3,000–10,000 mm | Storage lane depth commonly 4–20 pallets | Separate loading and unloading aisles are normally required | Food and beverage distribution, date-sensitive goods, and high-throughput order fulfillment | Reliable FIFO control, reduced travel distance, and efficient pallet movement |
| Cantilever Racking | Horizontal arms extend from vertical columns to store long, bulky, or irregularly shaped products. | 250–2,000 kg per arm level | 2,000–8,000 mm | 1,200–2,400 mm per storage section | Approximately 3,000–4,000 mm for forklift operation | Steel tubes, timber, pipes, profiles, furniture, panels, and other long loads | Unobstructed front access, adjustable arm levels, and easy handling of oversized products |
| Longspan Shelving | Manually loaded shelving with wide-span beams and steel or particleboard decks. | 100–800 kg per level | 1,500–3,000 mm | 1,200–2,400 mm | Not normally required; designed for pedestrian access | Hand-loaded cartons, components, tools, maintenance supplies, and small-to-medium items | Flexible configuration, easy assembly, good visibility, and suitable for manual picking |
| Multi-Tier Racking | Several elevated storage and picking levels are connected by stairways, walkways, or shelving platforms. | 150–600 kg per level | 3,000–8,000 mm total system height | 1,200–2,400 mm per bay | Not normally required on the picking levels | Small-parts warehouses, e-commerce fulfillment, archives, and order-picking operations | Uses vertical space efficiently and creates multiple manual picking levels without expanding the building footprint |
| Carton Flow Racking | Cartons or totes move forward on inclined rollers or wheels after being loaded from the replenishment side. | 50–250 kg per lane or level | 1,500–3,000 mm | 900–2,100 mm | Pedestrian picking aisles; forklifts typically operate on the replenishment side | Piece-picking, fast-moving consumer goods, spare parts, and order assembly areas | Improves FIFO rotation, reduces picker walking, and separates replenishment from picking activities |
