What Is Double Deep Racking?
Double deep racking is not the same as drive-in racking or mobile racking; it is a separate category of racking system. These systems all have unique components. Instead, Double deep racking refers to a configuration used with standard adjustable pallet racking.
This configuration consists of two rows of standard APR tracks back-to-back. However, access is only possible from one side. Forklifts can directly retrieve pallets from the front positions. To access the rear pallet positions, operators must use specialized equipment: forklift extension poles or forklifts equipped with telescopic forks.
This setup creates a pallet storage solution with higher density than standard selective shelving. Crucially, compared to ultra-high-density systems like drive-in shelving, it retains a significant degree of direct pallet access selectivity. This balances space utilization and operational costs.
Why Choose Double Deep Racking?
Maximise Storage Space
Reducing the number of aisles in your warehouse layout directly translates to a significant boost in usable storage area.
High Levels of Productivity
Pallets can be loaded and unloaded with impressive speed and efficiency, minimizing handling time per load.
Reduce Damage
Implementing guide rails on upper storage tiers significantly enhances operational safety and accuracy.

Advantages of Double Deep Pallet Racking
✓ Double deep racking boosts storage density significantly over standard adjustable racking, maximizing space without major operational changes.
✓ Access remains efficient, with roughly 50% of pallets immediately accessible, supporting good product rotation. The system typically achieves over 80-90% space utilization.
✓ This solution balances selective racking and high-density systems, operating on LIFO (Last-In, First-Out) inventory management.
✓ It increases usable space by eliminating unnecessary aisles and handles virtually any standard pallet load.
✓ Installation and modification are quick, similar to adjustable racking, reducing handling time and labor for faster stock rotation.
✓ The modular design allows easy reconfiguration or expansion as needs change, offering long-term flexibility.
✓ Safety is enhanced through integrated accessories like guards and netting. Components use durable pre-galvanized steel to ASTM standards, often including traceability features.
Flexibility
Double deep racking utilizes identical structural components to standard pallet racking (APR). This inherent compatibility offers significant operational flexibility. Should your storage strategy evolve, the system can be efficiently disassembled and reconfigured directly into a selective layout. This transformation requires no additional parts and minimizes operational downtime during the changeover process.
Increase Storage Capacity
Double deep racking effectively doubles the pallet positions available compared to a selective racking layout occupying the same aisle footprint. This design maximizes storage volume within constrained warehouse areas.
Last In, First Out (LIFO)
Double deep racking inherently operates on a Last In, First Out (LIFO) inventory management basis. This means the pallet most recently placed into a storage lane becomes the first one retrieved during picking operations.
Due to this LIFO behavior, double deep racking is generally not recommended for perishable inventory requiring consistent rotation.
Double Deep Racking Frames
Frames serve as the primary structural elements within a double deep racking installation. Each frame assembly incorporates two vertical uprights, diagonal cross-bracing, base plates for stability, and essential fastening hardware like bolts and nuts.
Aceally provides an extensive selection of frames featuring a durable galvanized finish. This protective coating offers superior corrosion resistance and longevity, significantly outperforming standard painted alternatives in demanding warehouse environments.
Main applications of Double Deep Racking for Pallets
Double deep racking significantly boosts storage density by placing pallets two deep within each row. This setup delivers major space savings compared to single-deep systems, though it operates on a LIFO (Last-In, First-Out) principle, meaning the most recently stored pallet must be accessed first.
This configuration shines in specific warehouse environments where maximizing space is paramount and the LIFO access method aligns with inventory flow. Key operational scenarios where it proves highly effective include:
- High-Volume SKUs: Ideal for products consistently stored in large quantities, requiring multiple pallets of the same item per location.
- Uniform Product Lines: Exceptionally efficient for warehouses handling large volumes of identical SKUs with minimal variation.
- Stable, Longer-Term Inventory: Well-suited for goods with moderate to slow turnover rates. It’s generally not the best fit for highly perishable items needing strict FIFO (First-In, First-Out) rotation due to the inherent LIFO access.
- Space-Constrained Operations: The optimal choice when the critical need for increased storage capacity outweighs the requirement for instant, unrestricted access to every single pallet position.

how much does double deep pallet racking cost
Costs swing based on height, capacity, bay count, and current steel prices. Always get custom quotes – Aceally Pallet Racking supplier details matter!
double deep pallet racking dimensions
Heights usually run 8-12 ft; beam lengths (often 8-10 ft) depend on your pallet depth including overhang. Crucially, match this to your forklift’s reach capability.
