Longspan Shelving vs Pallet Racking: Which Storage System Is Right for You?

Longspan shelving and pallet racking can look similar from across a warehouse: both use upright frames and horizontal load-bearing members. But they serve different handling tasks, and choosing the wrong system can create operational and safety problems. The most important question is not 'How heavy is the product?' but 'How will it be put away and picked?'

The key difference: hand loading versus forklift loading

Dexion Ultima Longspan 2 is designed as a hand-loaded shelving system. Staff place cartons, parts, tools or other suitable goods directly onto the shelves. The LS2 design manual explicitly states that the system is not suitable for loading by forklift and is not pallet racking.

Selective pallet racking, such as Dexion Speedlock Mk8A, is designed around forklift handling of pallets or suitable load units. It provides dedicated pallet positions within a system engineered for the intended pallet sizes, weights, handling clearances and site conditions.

When longspan shelving makes sense

Choose longspan shelving when the main task is manual picking and you need adjustable levels for cartons, loose stock, spare parts or other items that staff can safely handle. It suits storerooms, maintenance stores, parts distribution and warehouse pick faces where stock is accessed directly without lifting pallets into rack locations.

A modular run of starter and add-on bays can help organise stock by SKU or product size. With LS2, beam levels adjust at 50 mm intervals, allowing the arrangement to suit stock changes within the approved configuration.

When pallet racking makes sense

Choose pallet racking when goods arrive and remain in palletised loads, and a forklift is used to put pallets away or retrieve them. Selective racks are especially useful when individual pallet positions need to be accessed directly. The design needs to consider the forklift type, operating aisle, pallets, beam elevations and available building height.

Pallet racking may also support some specially designed heavy-duty shelving or other applications, but that does not make every shelf-like assembly a suitable pallet storage rack. The final system must be designed for the intended handling and loads.

Capacity: why a simple kilograms comparison is misleading

Both systems can have substantial structural capacity, but the safe working load cannot be determined by a product name alone. With longspan shelving, the frame, beams, decking and support arrangement all matter. With pallet racking, the beams, frames, bracing, floor anchors, slab and layout must be assessed together. A load number from one component is not a universal bay capacity.

If you are planning MDF or other board decking on longspan shelving, don't copy a published particleboard figure without confirming that the board and support configuration have been assessed. For pallet racking, don't estimate a rack capacity from beam colour or an upright's appearance.

Space planning and workflow

Longspan shelving is often arranged for people walking or working with trolleys along picking aisles. Pallet racking needs forklift manoeuvring and safe clearance around loads and equipment. A layout that maximises storage locations on paper can perform poorly if aisles are too tight or popular stock is difficult to reach.

Consider stock turnover, picking frequency, access to fast-moving items and whether you need full-pallet storage, case picking, or both. Many warehouses benefit from different storage systems in different zones rather than forcing every product into one rack type.

What about drive-in, push-back and pallet flow?

These are specialised alternatives to conventional selective pallet racking when storage density or stock rotation is the overriding requirement. They involve different access patterns and material-handling arrangements. For example, pallet flow uses gravity-fed tracks for first-in, first-out movement, while push-back storage is generally last-in, first-out. A design assessment is needed before selecting these systems.

A simple decision checklist

Ask four questions: (1) Are stock units manually picked or moved on pallets by forklift? (2) What are the actual item or pallet dimensions and weights? (3) How frequently must each SKU be accessed? (4) What space, floor condition and handling equipment are available? These answers help determine which type of system to investigate.

Frequently asked questions

Can I put a pallet on longspan shelving? Do not treat LS2 as pallet racking or load it by forklift; it is intended for hand-loaded storage.

Is pallet racking always the best choice for heavy cartons? Not necessarily. Handling method, approved loads and workflow matter; get advice on an appropriate system.

Can one warehouse use both? Yes. Separate zones for pallet reserve stock and manual order picking are often practical, subject to layout and safety requirements.
