What Is Double Deep Racking?

What Is Double Deep Racking?

Double deep racking is a high-density pallet storage system designed to increase warehouse capacity without expanding the floor space. It places two pallets deep on each side of the aisle, allowing operators to store more goods while maintaining a relatively simple rack structure.

Key Features

1. Higher Storage Density

Compared with standard selective racking, double deep racking can increase storage capacity by 30%–50%, making it an ideal solution for warehouses with limited space but large inventory volume.

2. Operated by Special Forklifts

The system requires reach trucks equipped with double-deep forks to access the rear pallet positions.

3. LIFO Inventory Management

Because the rear pallet is accessed after removing the front one, this system mainly follows a LIFO (Last In, First Out) principle. It is best suited for products with low FIFO requirements.

4. Strong and Reliable Structure

The rack is composed of uprights, beams, bracing, and safety accessories. It looks similar to selective racking but offers double-depth pallet locations.

Ideal Applications:

FMCG and consumer goods

Food, beverage, paper products

Warehouses storing large quantities of the same SKU

Advantages

30–50% higher storage density

Lower cost compared with other high-density systems

Simple structure and easy maintenance

High safety and high space utilization

Limitations

Requires special double-deep reach trucks

Not suitable for strict FIFO inventory

Higher operating skill is needed to access rear pallets
