Double Deep Pallet Racking

What Is Double Deep Pallet Racking?

Double deep racking is a type of storage system used in warehouses to store pallets of goods with two rows of pallets set back to back. This allows for the storage of pallets two deep, effectively doubling the storage capacity in the same floor space. It is particularly suitable for warehouses with volumes of identical products or that operate a Last In, First Out (LIFO) process.

Some of the most common specifications and considerations are:

• Dimensions – As standard pallets are approximately 1200mm deep, most double deep racks are around 2450mm deep to accommodate two pallets back to back.
• Heights – The height of the racks will depend on the ceiling height of the warehouse and the reach capacity of the forklifts, meaning some double deep racks can be up to 12cm.
• Load capacity – Each level of racking has specific weight capacities depending on the materials and design of the rack, and the range can be between100kg and 3000kg.

There are a variety of accessories that double pallet racking can have to enhance functionality, safety and efficiency, such as:

• Pallet Support Bars – These are placed between the beams to provide additional support for pallets, especially useful for pallets that are not strong enough to span the distance between beams.
• Row Spacers – These connect back to back rows of racks for stability, maintaining uniform spacing and alignment.
• Wire Mesh Decking – This is laid over the beams to create a solid shelf for storing items. It’s particularly useful for non-palletised goods or pallets that are smaller than the rack span. Mesh at the back of shelving can also prevent products from falling out of the back of pallets.
• Load Stops – These are barriers attached to the back of the rack to prevent pallets from being pushed too far and falling off the back.
• Guide Rails, Frame Guards or Rack Protectors – Installed along the floor, they help guide forklifts, preventing accidental damage to the racking system and minimising impact damage.
• Safety Pins or Clips – These secure beams to the uprights, preventing them from dislodging during loading and unloading.
• Labelling and Signage – Proper labels and signs for identification, weight capacity and safety instructions are crucial for efficient and safe operation.
