A storage racking project should not begin with, “How many bays do you need?” It should begin with a more important question: what must your warehouse be able to handle six, twelve or twenty-four months from now? This guide explains the practical checks that purchasing managers, warehouse managers and factory operators should make before selecting a racking system and supplier.
A Racking Project Is an Operational Decision, Not Only a Steel Purchase
The system you install affects receiving, put-away, replenishment, stock rotation, picking, forklift travel, product protection and future capacity. A layout can look efficient on a drawing yet perform poorly when trucks arrive, staging areas fill up and operators need to retrieve stock quickly.
1What Are You Storing—and How Does It Move?
A storage racking system must match the product and handling method, not only the available floor area. Palletised inventory, long materials, fast-moving cartons, irregular goods and high-volume stock each create different access and load requirements.
Your supplier should ask how goods enter the warehouse, where they are staged, how frequently each SKU is picked and whether stock is moved by forklift, reach truck, pallet jack or manual picking.
- Pallet dimensions, orientation, condition and maximum loaded weight
- Number of SKUs and average pallet quantity per SKU
- Fast-moving, slow-moving and seasonal inventory profiles
- FIFO, FILO or flexible stock-rotation requirements
- Manual picking, pallet retrieval or mixed handling operations
- Long, bulky, fragile or irregularly shaped materials
Selective pallet racking is commonly considered when direct access to many different palletised SKUs is important.
Which Storage Racking System Fits Your Inventory?
The best system depends on the balance between access, storage density, stock rotation and handling equipment. There is no single racking configuration that suits every warehouse.
| Racking system | Best suited to | Main advantage | Planning consideration |
|---|---|---|---|
| Selective pallet racking | Warehouses with many SKUs and frequent pallet access | Direct access to individual pallet positions | Requires sufficient aisle space for handling equipment |
| Double-deep pallet racking | Operations holding several pallets per SKU | Higher density than conventional selective layouts | Requires compatible reach equipment and reduced direct access |
| Drive-in racking | High pallet quantities with a relatively small number of SKUs | High-density storage with fewer access aisles | Commonly operates on a first-in, last-out basis |
| Multi-tier heavy-duty racking | Small and medium goods stored in high-clearance buildings | Creates usable storage levels within existing vertical space | Requires planning for stairs, handrails, gates and movement between levels |
| Specialised long-span storage | Cartons, loose goods, bulky products and hand-picked inventory | Flexible shelf dimensions for non-palletised products | Shelf loading and picking ergonomics must be assessed |
| Cantilever and specialised storage | Pipes, steel bars, timber, panels and other long materials | Open-front access for long or awkward loads | Arm capacity, load length and material stability are critical |
Drive-In Racking
Suitable when storage density is more important than immediate access to every pallet and the operation carries larger quantities per SKU.
Multi-Tier Storage
Useful for hand-picked cartons and smaller goods when the warehouse has sufficient clear height but limited ground-floor capacity.
Specialised Long-Span Storage
Long and awkward materials need open access, suitable support spacing and load control rather than a standard pallet-only configuration.
A structural or mezzanine solution can turn suitable overhead space into a practical working or storage level.
2Your Warehouse Height Is an Asset—Use It Properly
When ground-floor storage reaches its limit, relocating or renting additional premises may appear to be the only option. In some facilities, a better layout or multi-tier configuration can create more usable capacity within the existing building.
The objective is not to fill every cubic metre. It is to use height without making picking, replenishment, lighting, access and safety more difficult.
Information your supplier should verify
- Clear height below roof members, lighting and services
- Column positions, wall clearances and door openings
- Forklift lift height and turning requirements
- Goods movement between ground and upper levels
- Staircase, handrail, loading gate and edge-protection requirements
- Activities that must continue below or beside the proposed structure

3Do Not Select Storage Racking by Price Per Bay Alone
The cheapest quotation can become the most expensive option when the installed layout restricts forklift access, causes poor stock rotation, creates unused locations or cannot accommodate future pallet sizes.
A practical quotation should define
- Maximum unit load and stated load assumptions
- Frame height, depth, beam length and beam levels
- Number of usable pallet or shelf positions
- Required aisle widths and handling-equipment assumptions
- Anchoring, protectors, mesh, barriers and related accessories
- Delivery, unloading and installation responsibilities
- Proposed installation sequence and site requirements
- Options for future extension or reconfiguration
Warning signs in a quotation
- The proposal is based only on bay quantity without a site layout
- Pallet weight or product dimensions are not recorded
- No allowance is made for forklift turning or staging space
- The supplier assumes all floor areas and levels are suitable
- Safety accessories are treated as optional without explanation
- Expansion is discussed only after the initial system is finalised
Compare usable capacity, not steel quantity
Two quotations may include a similar number of frames and beams but provide very different usable capacity. Compare the number of accessible storage positions, handling time, aisle requirements and ability to adjust the layout.
SKL Metal Systems offers industrial pallet racking systems as well as racking accessories for complete warehouse configurations.
Practical Racking Selection Scenarios
The following examples show how stock profile and operational priorities can change the recommended direction. They are planning examples rather than claims about individual customer projects.
Spare-Parts Distributor
A distributor carries many palletised SKUs, but only one or two pallets of each item. Direct access is more valuable than maximum density.
Likely direction: selective pallet racking with clear picking and replenishment zones.
Manufacturer With Repeated Pallets
A factory stores larger quantities of the same finished products and needs to reduce the number of aisles used for storage.
Likely direction: drive-in or double-deep racking, subject to stock-rotation and equipment requirements.
Carton-Picking Warehouse
A business has many small and medium cartons, increasing SKU count and substantial unused clear height.
Likely direction: long-span or multi-tier storage with clearly planned stairs, walkways and replenishment routes.
4Installation Must Fit Your Business, Not Interrupt It
Receiving, production and dispatch cannot always stop while a racking project is installed. For an active warehouse, the installation sequence should be planned around stock movement, working hours and areas that must remain accessible.
A phased installation may include
- Clearing and marking one work zone at a time
- Installing empty sections before transferring stock
- Keeping emergency routes and loading areas unobstructed
- Scheduling disruptive activities outside peak operating hours
- Coordinating unloading space for frames, beams and accessories
- Completing final checks before each area is released for use
SKL Metal Systems states that it has its own trained installation team, supporting closer coordination between the proposed layout and on-site installation. Learn more on the SKL Metal Systems company profile .
Installation planning should consider access for materials, active operations and the sequence in which completed areas will be loaded.
Not Every Product Needs a Pallet Rack
Using heavy pallet racking for every item may create inefficient shelf heights and difficult manual picking. Smaller cartons, documents, spare parts and hand-picked products may be better organised with light-duty or long-span shelving in a dedicated zone.
A mixed warehouse can combine pallet storage for reserve stock with lower-level picking shelves for frequently accessed items. This reduces unnecessary forklift handling and helps separate pallet movement from manual picking.

5Choose a Supplier That Can Support Your Next Change
Your warehouse may not look the same next year. New product lines, increased pallet volume, changing pick frequency and different handling equipment can all affect the suitability of the original layout.
Future-ready planning does not mean buying unnecessary capacity immediately. It means avoiding decisions that make future expansion difficult or force the warehouse to replace otherwise usable components.
Reserve Logical Expansion Zones
Decide where additional bays, picking shelves or staging space could be added without blocking doors, columns or main travel routes.
Plan Adjustable Beam Levels
Consider whether beam positions can be revised when pallet heights or product dimensions change.
Separate Storage Profiles
Create zones for fast-moving pallets, reserve inventory, cartons and long materials instead of forcing every load into one system.
Retain Project Information
Keep the approved layout, load assumptions and component details available when making future modifications.
What Should a Storage Racking Supplier Do Before Installation?
A reliable supplier should convert your operational requirements into a practical layout before materials arrive on site. The following process helps reduce assumptions and last-minute changes.
Collect Data
Record warehouse dimensions, pallet details, load weights, SKU profile, handling equipment and target capacity.
Assess the Site
Check columns, doors, clear height, floor conditions, services, loading areas and operational restrictions.
Develop the Layout
Balance usable storage positions with aisle access, picking routes, staging space and future expansion.
Plan Installation
Confirm delivery, unloading, work zones, installation stages and the information needed before loading begins.
What Information Should You Send for a Racking Quotation?
Better input produces a more useful quotation. Even a basic warehouse sketch and several clear photographs can help the supplier identify potential constraints before a site discussion.
- Warehouse length, width and clear height
- Column grid, doors, shutters and loading-bay positions
- Pallet length, width, height and maximum loaded weight
- Required pallet quantity or shelf capacity
- Product type and number of SKUs
- Forklift or reach-truck model and lift height
- Current warehouse photos and floor plan
- Stock-rotation and picking requirements
- Target installation schedule
- Expected growth over the next one to two years
