Double Deep Pallet Racking

Double Deep Pallet Racking increases pallet storage density compared with conventional selective racking while maintaining access to a wider range of stored inventory. By reducing the amount of floor space dedicated to aisles, it provides deeper storage for batch-held and finished-goods inventory, making it particularly suitable for products stored in multiple pallets of the same SKU. It offers a practical balance between increased storage density and pallet accessibility.

Double Deep Pallet Racking stores two pallets deep on each side of the aisle, with two double-deep rows positioned back to back. This reduces the number of aisles required compared with single-deep selective racking while using standard racking components. Deep-reach trucks with extending forks or a pantograph mechanism are used to access the rear pallet. The system operates on a LIFO basis within each pair of positions, meaning the front pallet must be moved before the rear pallet can be accessed.

specifications

• Frame depth: two single-depth frames joined back to back with row spacers
• Beam lengths: similar to selective racking, depending on pallet size
• Heights: commonly up to about 10 m, subject to truck capacity at full reach
• Capacity: per pallet position and per beam level, per the supplier’s load table

Operational & Commercial Benefits

• More pallet positions in the same floor area than selective racking, using standard structural components
• Lower cost than automated or motorised dense systems
• Good fit for SKUs with multiple pallets

Ideal for

Finished goods stores, packaging and paper stores, agricultural supplies, and distribution of products held in batches.

Buyer’s guide

• Check the truck’s capacity at full fork extension. The rated capacity of a deep-reach truck falls as the load is held further out and higher up.
• Driver visibility. The rear pallet position is hard to see at height. Camera systems and laser guides are available and worth considering.
• Plan stock by SKU. Because access is LIFO within each pair, the layout works best where pairs hold the same product and batch.
• Pallet quality is important, since the driver cannot easily see problems at the rear position.
