Types of Warehouse Racking: A Complete Guide

Efficient warehouse storage starts with the right racking system. Choosing the right type of racking can improve space utilization, streamline operations, and reduce costs. In this guide, we’ll explore the most common types of warehouse racking systems, their benefits, and ideal use cases.

1. Selective Pallet Racking

Overview:

Selective racking is the most widely used system in warehouses. It consists of single-deep or double-deep racks, allowing direct access to every pallet.

Key Benefits:

• High selectivity for multiple SKUs

• Easy inventory management

• Compatible with standard forklifts

Best For:

Warehouses with diverse products and moderate storage density.

2. Drive-In Racking

Overview:

Drive-in racking is a high-density system where forklifts enter the storage lanes to load and retrieve pallets.

Key Benefits:

• Maximizes floor space

• Ideal for bulk storage

Flow Type:

LIFO (Last-In, First-Out)

Best For:

Large quantities of similar products with low turnover.

3. Pushback Racking

Overview:

Pushback racks use nested carts on inclined rails. Pallets are loaded from the front and pushed back as new pallets are added.

Key Benefits:

• High-density storage

• Reduces aisle space

Flow Type:

LIFO (Last-In, First-Out)

Best For:

Medium-turnover products with limited SKU variety.

4. Pallet Flow Racking

Overview:

Pallet flow racks use gravity-fed roller tracks to move pallets forward automatically.

Key Benefits:

• Perfect for FIFO inventory rotation

• High-density storage

Flow Type:

FIFO (First-In, First-Out)

Best For:

Perishable goods or time-sensitive inventory.

5. Double-Deep Racking

Overview:

Double-deep racking stores pallets two deep, increasing storage density without sacrificing too much selectivity.

Key Benefits:

• Higher storage capacity

• Requires specialized forklifts

Best For:

Warehouses with fewer SKUs and high volume.
