The Most Common Pallet Racking Systems: Which One Is Right for Your Warehouse?

What are the most common types of pallet racking in industrial applications? We have the answers, along with the pros and cons of each, to help you make the right decision for your warehouse. So, let’s break down each type of industrial pallet rack.

Selective Pallet Racking

Selective pallet racking in industrial applications is the most widely used system in warehouses. It offers direct access to all pallets, making it ideal for operations with a wide variety of SKUs and moderate inventory turnover. This system consists of upright frames and horizontal beams that form levels for pallet storage.

The layout of selective pallet racking can be easily modified to accommodate changing inventory needs. It’s particularly suitable for warehouses that need to store a diverse range of products and require frequent access to individual pallets. However, it may not be the most space-efficient option for facilities dealing with large quantities of identical items.

SELECTIVE PALLET RACKING
PROS	CONS
Easy access to pallets Flexible configuration Cost-effective Simple inventory management	Not ideal for bulk storage Requires wider aisles for forklifts Lower storage density Less space-efficient than some others

Double Deep Racking

Double deep racking is an extension of selective racking that allows pallets to be stored two deep on each side of an aisle. This system significantly increases storage density compared to standard selective racking, making it an excellent choice for warehouses looking to maximize their storage capacity.

Double deep racking is particularly effective for storing large quantities of similar items or for operations with a lower turnover rate. However, specialized forklifts with telescopic forks are required to reach the back pallets. This system also sacrifices some accessibility, as the front pallet must be removed to access the one behind it.

DOUBLE DEEP RACKING
PROS	CONS
Increased storage capacity Good for bulk storage Better space utilization Reduced aisle space needed	Requires specialized forklifts Less accessible than selective racking Potential for product damage LIFO systems may not suit inventory

Drive-In/Drive-Through Racking

Drive-in and drive-through racking systems are high-density storage solutions that allow forklifts to drive directly into the rack structure. These systems are ideal for bulk storage of homogeneous products and are particularly useful in cold storage environments where space is at a premium.

In a drive-in system, forklifts enter and exit from the same side, following a last-in, first-out (LIFO) inventory management method. Drive-through systems, on the other hand, allow entry from both sides, enabling a first-in, first-out (FIFO) approach. Both types significantly increase storage density but sacrifice accessibility to individual pallets.

DRIVE-IN/DRIVE-THROUGH RACKING
PROS	CONS
Strong space utilization Ideal for bulk storage Good for cold storage High-density	Limited selectivity Requires skilled forklift operators Not suitable for a diverse inventory Higher risk of damage to racks

Push-Back Racking

Push-back racking is a high-density storage system where pallets are stored on wheeled carts that move along inclined rails. When a new pallet is loaded, it pushes the existing pallets back. This system typically allows for storage of two to six pallets deep per level.

Push-back racking is excellent for storing multiple SKUs in a high-density environment. It operates on a last-in, first-out (LIFO) basis, making it ideal for products with a shorter shelf life or where stock rotation is less critical. However, it’s more expensive than basic systems and requires careful attention to pallet weights and sizes.

PUSH-BACK RACKING
PROS	CONS
Good storage density LIFO inventory management Multiple SKUs per lane Faster loading than drive-in	Not suitable for FIFO operations Requires consistent pallet sizes Potential for cart jamming More expensive than basic systems

Pallet Flow Racking

Pallet flow racking, also known as gravity flow racking, uses inclined rails with rollers or wheels to move pallets from the loading end to the picking end. This system automatically rotates stock on a FIFO basis, making it ideal for perishable goods or date-sensitive materials.

Pallet flow racking offers high-density storage and is particularly effective in operations where stock rotation is crucial. It’s often used in distribution centers and manufacturing facilities where large quantities of similar products are handled. However, it has a higher initial cost and requires consistent pallet sizes for smooth operation.

PALLET FLOW RACKING
PROS	CONS
High-density storage FIFO inventory management Automatic stock rotation Reduced handling time	Higher initial cost Requires consistent pallet sizes Limited selectivity Potential for pallet jams

Cantilever Racking

Cantilever racking is designed to store long or irregularly shaped items that don’t fit well on standard pallet racking. This system uses vertical columns with horizontal arms extending out to support loads, eliminating the need for front uprights.

Cantilever racking is highly versatile and can be easily adjusted to accommodate different product sizes. It’s commonly used for storing items like lumber, pipes, furniture, and other long or bulky products. While it’s excellent for these specialized items, it may not be the most efficient choice for standard palletized goods.

CANTILEVER RACKING
PROS	CONS
Versatile for non-standard items Easy to adjust arm positions Good for long/bulky items Unobstructed access for loading	Not suitable for standard pallets Can be inefficient in the use of space May require special handling equipment Higher cost for standard storage
