Double Deep Pallet Racking System – Design and Installation

High-density storage with a reduced number of aisles

How do double deep racking systems work?

Double deep racking combines standard pallet racking components with a specialist forklift truck attachment to allow pallets to be stored two deep, as well as back-to-back, thereby removing the number of aisles required when compared to a standard single-deep solution.

Generally, the products stored in each of the two locations would be the same; and since the front pallet will need to be removed to access the rear pallet, the last-in-first-out principle applies.

This system requires specialised equipment, such as extendable or telescopic forklifts, and generally, requires slightly wider aisles. However, where 100% selectivity is not required, double-deep can be a very cost-effective method of increasing space utilisation and operational efficiency.

System Benefits

  • Enhanced storage capacity as a double deep solution can increase pallet storage count by up to 50%.
  • Operationally flexible: can be reconfigured into standard single-deep and vice-versa.
  • A comparatively high-density and low capital expenditure storage medium to other solutions
  • Well suited for SKUs that have a high stock rotation
  • Eliminates unneeded aisles and increases floor space utilisation
  • Reduced aisles result in a lower level of lighting and electrical infrastructure and power usage
  • Can be adapted to suit most pallets and loadings.

Common Uses

Double Deep solutions are very versatile and can cater for a wide range of operations. However, they are particularly suitable for warehouses that possess the following:

  • Products with more than one pallet per Stock Keeping Unit (SKU)
  • Non-perishable stock, where first in first out does not need to be strictly adhered to
  • A good quality stock management system, where restricted pallet access does not represent an operational issue
  • A need for storage capacity that outweighs the requirement for 100% selectivity

Product review

“We contacted SEC following an uninspiring performance from two alternative suppliers. We have limited experience in installations of this size so we were heavily reliant on our chosen supplier to help us design and deliver an appropriate solution.

During the design phase, SEC Storage identified a storage solution which had not been offered to us previously, and one which allowed us to store many more pallets than we had expected (a very welcome surprise). I quickly ascertained that SEC Storage was a capable and well-run business and one which could deliver exactly what we needed.”
