Higher-Capacity Pallet Storage in Malaysia
Double Deep Pallet Racking System
A higher-density derivative of selective pallet racking that stores pallets two positions deep, making it practical when each SKU occupies several pallet positions.
Double-deep racking can increase storage capacity by up to 35% compared with selective pallet racking. Approximately half of the pallet positions remain directly accessible, and suitable deep-reach handling equipment is required.
Double-Deep Racking at a Glance
Is Double-Deep Racking Right for Your Warehouse?
This system balances higher pallet density with controlled access. It is most useful when a warehouse carries fewer SKUs than a typical selective-racking operation and stores several pallets of each SKU.
Best suited for
- Operations where each SKU has several pallets
- Warehouses needing more capacity than standard selective racking
- Stock profiles that can accept controlled pallet accessibility
- Facilities with suitable deep-reach handling equipment
- Layouts seeking a balance between density and aisle-based access
Another system may be more suitable when
- Direct access to every pallet is essential
- The warehouse carries many SKUs with only one or two pallets each
- The existing forklift cannot reach the rear pallet position
- Maximum storage density is required for very large quantities of fewer SKUs
- Frequent access to individual rear pallets would disrupt daily operations
What Is Double-Deep Pallet Racking?
Double-deep pallet racking is derived from selective pallet racking. Two rack rows are positioned together so pallets can be stored two positions deep from the working aisle. The front pallet position remains directly accessible, while the rear pallet is reached using suitable deep-reach equipment.
Pairing rack rows reduces the number of aisles required compared with conventional selective layouts. The trade-off is lower pallet selectivity, so SKU quantities and access frequency should be evaluated before the configuration is chosen.
Two-Deep Storage
Front and rear pallet positions increase the number of pallets stored between aisles.
Higher Capacity
Can provide up to 35% more capacity than selective pallet racking.
Controlled Access
Approximately half of the pallet positions can be accessed directly from an aisle.
Reach-Truck Operation
Suitable deep-reach equipment is required to handle pallets in the rear position.
Double-Deep Racking Layouts and Applications
The final arrangement should follow the pallet profile, SKU quantity, reach-truck capability and warehouse dimensions. These SKL product images illustrate double-deep and selective pallet-storage configurations.
Key Information to Confirm Before Quotation
A double-deep system should not be selected from floor area alone. Pallet dimensions, pallet load, SKU profile, reach-truck capability, aisle space and usable height all affect the proposed configuration.
| Information to confirm | Why it matters |
|---|---|
| Pallet length, width and loaded height | Dimensions influence rack depth, beam spacing, storage levels and operating clearances. |
| Maximum load per pallet | The heaviest loaded pallet is required to determine the appropriate rack configuration. |
| Number of SKUs | The system is more practical when several pallet positions can be assigned to each SKU. |
| Pallet quantity per SKU | Front and rear positions should suit the actual stock quantity and access pattern. |
| Access and stock-rotation requirement | Rear pallets are not directly accessible while a pallet occupies the front position. |
| Required pallet positions and levels | The capacity target influences rack rows, height, levels and aisle arrangement. |
| Reach-truck model and lift height | The equipment must reach the rear pallet and suit the proposed aisle and rack height. |
| Warehouse dimensions and clear height | Floor area, columns, doors and overhead obstructions affect the final layout. |
| Floor and installation conditions | The installation area and site constraints should be reviewed before the layout is agreed. |
Main Benefits and Trade-Offs
Potential benefits
- Up to 35% more storage capacity than selective pallet racking
- Fewer aisles than a conventional selective-racking layout
- Good fit where each SKU has several pallets
- Balances higher density with aisle-based pallet handling
Operational trade-offs
- Only approximately half of pallet positions are directly accessible
- Rear pallets require the front position to be clear
- Special deep-reach handling equipment is required
- SKU allocation and replenishment need more planning than selective storage
Double-Deep vs Selective vs Drive-In Racking
These systems provide different balances between pallet accessibility, density and equipment requirements.
| System | Best suited for | Pallet access | Main consideration |
|---|---|---|---|
| Double-Deep Racking | Fewer SKUs with several pallets per SKU | Approximately half of positions directly accessible | Requires suitable deep-reach equipment |
| Selective Pallet Racking | Many SKUs and frequent pallet access | Direct access to every pallet | Uses more aisle space than denser systems |
| Drive-In Racking | Few SKUs with large pallet quantities | Deep-lane FILO access | Forklift enters the rack lane and selectivity is lower |
Reach-Truck, Pallet and Safety Considerations
The proposed rack height, rear-pallet reach and aisle arrangement must suit the actual material-handling equipment. Pallet condition, loading and rack protection should also be managed as part of daily operation.
- Confirm the reach truck can place and retrieve pallets from the rear position.
- Review lift height, aisle requirement, turning space and operating clearance.
- Confirm pallet dimensions, construction, condition and maximum loaded weight.
- Do not exceed the confirmed pallet or rack loading requirement.
- Plan front and rear pallet allocation around SKU quantity and access frequency.
- Keep working aisles and pallet-handling routes clear.
- Inspect visible rack or pallet damage and address maintenance requirements.
- Consider protection where handling equipment operates close to uprights.
Suitable racking accessories and safety protection can be considered according to the layout and operating environment.
