Stow pallet racking can increase the number of pallet positions in a warehouse, but the densest layout is not automatically the most productive one. The right specification depends on how often stock moves, how many pallet types you store, which handling equipment serves the aisles and how replenishment fits around picking. Before choosing a Stow-branded system, confirm the exact configuration being proposed and compare its storage capacity with its effect on access, travel and safety. A practical assessment starts with stock and workflow, then tests whether the racking, trucks, building and operating plan work together.

What does “Stow pallet racking” mean for a warehouse?

The phrase can refer to a Stow-branded pallet storage system, but it does not by itself identify one layout or operating method. A proposal may involve conventional adjustable pallet racking or a denser arrangement designed around a narrower selection of stock and access requirements. Product names, available configurations and specifications should be confirmed with the supplier serving your market rather than assumed from the general term.

Start by asking what the proposal includes: the racking configuration, bay and level arrangement, design load information, protective components, installation scope and any assumptions about pallets or handling equipment. If a project uses an existing Stow installation, confirm component compatibility before planning extensions or replacements. Similar-looking frames, beams and accessories should not be treated as interchangeable without verification.

The warehouse decision is broader than choosing a rack. The system must fit the building and the way goods enter, are stored, picked and dispatched. More pallet locations have limited value if operators struggle to reach the right stock or replenishment traffic interferes with order picking.

Compare racking configurations by access and stock flow

These common configurations illustrate the main trade-offs to discuss when reviewing a Stow pallet racking proposal. They are general system types, not a claim that every configuration is available under a particular local product range. Ask the supplier to identify the proposed system and explain its operating sequence.

Configuration Access to pallets Typical strength Main trade-off Consider it when
Selective pallet racking Direct access to each stored pallet position Flexible access across a broad stock range Aisles use floor area that a denser system might reduce Many SKUs need separate, straightforward access
Narrow-aisle racking Direct access, using equipment suited to narrower aisles Can use floor space more intensively while retaining individual access Requires compatible trucks, operating practices and aisle planning More capacity is needed without moving to deep-lane storage
Drive-in or drive-through racking Access is organised by lane rather than by individual pallet position Stores more pallets in a concentrated area Access and stock rotation depend on lane design and operating sequence There are multiple pallets of the same product or batch
Push-back or pallet-flow arrangements Pallets move within a lane; access is managed by lane and loading method Can support denser storage with defined replenishment and retrieval patterns Requires suitable stock profiles and attention to equipment and lane operation Inventory can be grouped into lanes and the rotation method suits the business

Selective racking is often the simplest starting point when staff need to reach different SKUs independently. Drive-in storage commonly limits direct access within a lane; push-back systems are commonly operated on a last-in, first-out basis, while pallet-flow designs can support first-in, first-out movement when configured and loaded for that purpose. Actual stock rotation depends on the equipment layout and process, so confirm how each lane will be loaded, picked and replenished before comparing capacity.

Assess storage density against daily warehouse flow

Storage density describes how much stock a layout can hold within its footprint. It does not tell you how quickly staff can retrieve a particular pallet, how easily replenishment can be completed or how much congestion will build at busy times. Compare usable capacity and operating effort, not just the number of positions shown on a plan.

Begin with a stock profile. Identify the number of active SKUs, pallets held for each one, the rate at which they move and whether particular goods need separate locations or rotation rules. A lane system can suit repeated pallets of the same product, but may be awkward when a lane contains stock that needs frequent individual access. Conversely, selective access can make it easier to reach varied stock but usually requires more aisle space.

Map the main journeys through the warehouse: receiving, put-away, replenishment, picking, consolidation and dispatch. Check whether inbound pallets will cross busy picking routes, whether replenishment can happen without blocking dispatch activity and whether operators can reach staging areas without unnecessary detours. Consider peak activity as well as an average shift; a layout that works when quiet may create queues when several processes converge.

For each candidate configuration, ask the supplier to show the locations that are accessible at the same time and how stock will be replenished. A plan should make clear which pallets are reserve stock, which are picked directly and whether additional moves are needed to reach a target pallet. Those extra touches can erode the practical benefit of a more compact arrangement.

Check the racking against handling equipment

Racking and material handling equipment must be specified as a working pair. Aisle width, turning space, rack height and the position of beams all affect the equipment that can serve the installation. Confirm the relevant truck type and its operating clearances with the equipment supplier and racking designer; do not select an aisle dimension by copying a figure from another warehouse.

Review the full operating envelope, including the truck’s ability to approach a bay, lift and place the intended load, and manoeuvre at aisle ends. Check any effects of mast height, load dimensions, pallet condition and floor conditions on the proposed arrangement. If the layout relies on specialised equipment, account for its availability, operator training, maintenance and impact on work practices as part of the decision.

Consider what happens when equipment is unavailable or a route is obstructed. If a particular truck is essential to reach a large share of stock, a breakdown may affect more than one task. A contingency plan might involve alternative equipment or a different operating sequence, but it should be tested against the actual layout and not assumed to work.

Fit the layout to the building and its constraints

A warehouse plan needs to reflect the building as it stands, not an empty rectangle. Mark columns, walls, doors, loading areas, floor changes, building services, fire protection and pedestrian routes before settling on bay positions. Confirm how these constraints affect rack rows, aisle ends, staging and access for maintenance or emergency response.

In New Zealand, include seismic design and applicable local building and workplace requirements in the project brief. The appropriate design depends on the site, building and proposed installation; a supplier’s general arrangement is not a substitute for project-specific review. Ask who is responsible for confirming the design assumptions and what information they need about the building and floor.

Leave room for operational changes where practical. If the business expects a different product mix, larger pallets or more picking activity, ask how the proposed layout could adapt. Future flexibility may be worth more than squeezing in a small number of additional positions that make later changes difficult.

Confirm load assumptions and safety provisions

Capacity should be based on the loads the warehouse will actually store. Provide accurate information on pallet dimensions, maximum loaded weight, load shape and any uneven or overhanging loads. A system designed around one pallet profile may not suit another, even if both fit the same general bay. Have the supplier document the applicable load information for the proposed arrangement, including any restrictions on beam levels or configuration.

Discuss the floor and installation as part of the design. The project team should confirm the relevant floor information, anchoring approach and installation requirements rather than assuming that an existing slab or old layout will support a changed system. Changes to bay geometry, load assumptions or building conditions may affect the design and should be reviewed before work proceeds.

Plan for day-to-day protection and inspection as well as initial installation. Depending on the layout and site assessment, this may include protection in vulnerable locations, clear operating procedures, visible load information and a process for reporting damage. Staff should know how to isolate a damaged area and whom to notify. Do not allow damaged components to remain in service on the assumption that the rack still appears stable; have them assessed by a competent person.

Keep pedestrian movement, vehicle routes and work areas in the design discussion. Racking rows should not create blind conflicts or obstruct designated routes, and staging should not spill into aisles. The right controls depend on the site and its operations, so verify the arrangement through a safety review before the warehouse starts using it.

A practical process for choosing a Stow pallet racking layout

  1. Build a usable stock profile. Record the pallet types, load details, SKU counts, stock quantities and movement patterns that the layout must support. Separate unusual or oversized loads from standard assumptions.
  2. Map the operating process. Show where goods arrive, where reserve stock sits, how picking is replenished and where completed orders wait for dispatch. Note existing congestion and avoid designing around a workflow that staff cannot sustain.
  3. Set the access requirement. Decide which stock needs direct pallet access, which can be grouped by product or batch, and what rotation method each product requires. This helps determine whether selective or lane-based storage is appropriate.
  4. Test equipment and building fit. Give the racking designer and equipment supplier the same layout and load information. Resolve aisle access, lift requirements, floor assumptions, building obstructions and pedestrian routes before comparing proposals.
  5. Compare operating consequences. Look beyond pallet positions. Ask how many handling moves a typical replenishment or retrieval requires, where queues could form and whether the operation can cope if key equipment is unavailable.
  6. Review the documented design and handover. Confirm the final configuration, load information, installation responsibilities, inspection arrangements and any restrictions. Make sure operators receive instructions that match the installed system.

Compare total operating cost, not just installation scope

A denser layout may require different handling equipment, changes to staff routines or more careful lane management. A less dense configuration may use more floor area but make individual pallets easier to retrieve. The relevant comparison is the cost and capacity of the whole operating system, not a rack-only quote.

Ask suppliers to clarify what their proposals include and exclude, including design work, installation, protection, alterations to existing equipment and any preparation required at the site. Then assess ongoing implications: equipment needs, maintenance, training, inspection, replenishment effort and the consequences of limited access. These items will vary by project, so use documented assumptions rather than relying on a general cost-per-position comparison.

Where two proposals appear close, test them against the same stock profile and operating scenario. For example, compare how each handles a fast-moving SKU that needs frequent replenishment as well as a slow-moving product held in reserve. A proposal that performs well across the actual mix may be a better fit than one that maximises capacity for a single product category.

Common planning mistakes to avoid

  • Choosing by position count alone. A capacity figure is useful only if the required pallets remain accessible and the workflow can keep up.
  • Assuming every pallet is standard. Different dimensions, weights and load conditions can change the suitability of a bay or lane.
  • Leaving equipment decisions until later. The truck and rack layout need to be assessed together, especially where narrow aisles or high storage levels are involved.
  • Ignoring replenishment and staging. Racking may fit on the plan while leaving too little usable space for receiving, picking or dispatch activity.
  • Changing an installation without checking the design. Altering levels, loads, components or layout can invalidate assumptions; obtain a proper review before making changes.

Frequently Asked Questions

Is Stow pallet racking suitable for every warehouse?

No single racking layout suits every stock profile, building or handling method. Ask the supplier to identify the proposed Stow configuration and assess it against your loads, equipment, access needs and workflow.

Does higher-density racking always increase usable capacity?

It can increase the number of positions within a given area, but the result depends on the building and the system’s access requirements. Allow for aisles, staging, replenishment and stock that needs direct access when comparing usable capacity.

What information should I provide for a racking proposal?

Provide pallet dimensions and maximum loaded weights, stock quantities, SKU and movement information, handling equipment details and a building plan with known obstructions. Also explain any stock-rotation requirements and how receiving, picking and dispatch currently work.

Can I add bays or reuse parts from an existing Stow installation?

Possibly, but compatibility and suitability need to be confirmed for the actual components and proposed arrangement. Ask the supplier or a qualified designer to review the existing installation, load assumptions and any changes before ordering or altering parts.

Should I choose selective or drive-in pallet racking?

Selective racking is worth considering when staff need direct access to many different pallets. Drive-in storage may suit repeated pallets of the same product where lane-based access is acceptable; compare retrieval sequence, stock rotation and replenishment needs before choosing.

What should happen if a rack is damaged?

Follow the site’s procedure to report the damage and keep the affected area out of use when its safety is uncertain. Have the rack assessed by a competent person and make repairs or replacements in line with the documented design, rather than improvising a fix.

Choose the system that supports the work

Stow pallet racking is a sound fit only when its capacity, access pattern and equipment requirements match the warehouse’s actual operation. Compare configurations using the same stock and workflow assumptions, confirm the design and load information, and review building and safety constraints before committing. The best proposal is the one that adds useful storage without making everyday put-away, picking and replenishment harder.
