| Selective pallet rack | 2 pallets per beam level; 1,000 kg gross load per pallet; 1,200 × 1,000 mm pallet footprint | 2,000 kg per beam level (2 × 1,000 kg) | Direct access to every pallet; suitable for many SKUs and regular forklift picking. Aisle width depends on the truck and load dimensions. | Confirm beam span, pallet overhang, required clearances, upright-frame capacity, floor slab capacity, and forklift turning space. |
| Selective pallet rack, higher load case | 2 pallets per beam level; 1,500 kg gross load per pallet; load includes pallet and goods | 3,000 kg per beam level (2 × 1,500 kg) | Useful where pallet positions remain individually accessible but heavier unit loads are stored. | Request a design calculation for the specified beam span and load arrangement; do not infer capacity from beam appearance alone. |
| Double-deep pallet rack | 4 pallets per bay level across two deep positions; 1,000 kg gross load per pallet | 4,000 kg per level across four pallet positions, subject to the engineered beam and frame design | Increases storage density by placing rows deeper; requires a deep-reach truck and reduces direct access to rear pallets. | Check truck reach, aisle geometry, load sequence, rear-pallet access, and the capacity of each beam level and frame. |
| Drive-in rack | Pallets stored several positions deep; example planning load: 1,000 kg gross per pallet | Capacity is determined by the number of pallets per lane and level and by the structural design; it is not a single universal bay rating. | High-density storage for a limited number of SKUs with larger, more uniform batches; typically uses last-in, first-out access within a lane. | Verify lane depth, forklift clearance, pallet quality, impact protection, and the intended loading and unloading sequence. |
| Carton or light-duty shelving | Hand-loaded cartons or bins; capacity must be specified per shelf or bay from the actual distributed load. | No pallet-beam capacity applies; obtain the rated shelf load and complete-bay load from the design documentation. | Fits small-item picking, low-level storage, and areas where frequent manual access is required. | Check shelf loading method, bay bracing, anchoring, access requirements, and whether the stated rating is per shelf or per complete unit. |
