Let’s explore each kind and the advantages and disadvantages of each so you can choose the right pallet racking system for your business.
What is a Pallet Racking System?
A pallet racking system is a storage system that stores pallets of items in horizontal rows on multiple levels, allowing for better storage density by taking advantage of available vertical space.
Pallets are loaded onto the racks and unloaded into the rack typically by a forklift truck.
Types of Racking Systems
Selective Pallet Racking: The Most Popular Racking Solution for Warehouse Storage Needs
The selective pallet rack, also known as static racking is the most popular pallet storage system among warehouses. Its popularity is due to its low cost and wide selection of upright heights and beam sizes for custom configuration.
It allows you to store loads at various heights, and it allows for access to 100% of the loads. Because you have direct access to each load, you have 100% “selectivity.”
Selective pallet racks have been around since the 1950s, but they continue to be popular because of their relatively low cost and many benefits.
Advantages of Selective Pallet Racking
- Easy assembly and de-install
- It can be configured in different ways for your industrial equipment
- Lower entry price compared to more complex racking systems
Disadvantages of Selective Pallet Racking
- Lower storage density compared to other types of racking
- Less efficient use of floor space due to many aisles
Double Deep Pallet Rack: Increase your Storage Space
Double deep warehouse racking systems share the same components as a selective racking system, except for one thing: the two rows of rack are installed adjacent to one another, which means a higher storage density is possible.
However, since they are two loads deep you will need a double deep reach truck with an extendable pantograph to load and unload from these pallet rack systems.
Advantages of Double Deep Pallet Rack
- Easy assembly and de-install
- Greater storage density than selective pallet rack systems
- It can be configured in different ways for your industrial equipment
- Lower entry price compared to more complex racking systems
Disadvantages of Double Deep Pallet Rack
- Reduction in selectivity to 50%
- Requires either a bottom beam level or longer beams to accommodate the outriggers of the double deep reach truck
- Requires more expensive loading and unloading equipment
Carton Flow Pallet Racks: The Ideal Storage Solution for Businesses With High Turnover Rates
If your business has high turnover rates for its products, you may want to consider using a carton flow rack system.
Carton flow racks are designed specifically for businesses that deal with small non-palletized, lightweight items and need to pick orders frequently and quickly.
It typically uses uprights and beams like a selective rack system; however, the lower levels are equipped with rollers mounted to rails to transport the cartons from the loading side to the picking side of the system, allowing workers at a ground level easy access when loading or unloading cartons.
It is common to have pallets stored above the carton flow rack.
Advantages of Carton Flow Rack Systems
- Fit for a combination of different carton sizes
- Uses gravity as a free power source
- Clear visibility of product inventory
- Enhanced efficiency for order fulfillment
Disadvantages of Carton Flow Rack Systems
- Carton flow racks are more expensive than standard pallet racking systems
- Typically requires manual unloading of pallets to load cartons into the system
Cantilever Racking System: Perfect for Long Loads
Cantilever racking systems utilize arms attached to upright posts to store long items such as pipes, carpet rolls, and lumber.
Built out of a combination of towers, arms, and bases, cantilever racks are ideal for storing long loads.
They employ vertical supports on the rear side of their structure and use arms that extend from the back to support loads with no vertical obstruction on the loading side of the system.
Advantages of Cantilever Racks
- Ideal for long loads
- Easy to install and reconfigure
- A broad number of capacity ranges
- No vertical obstruction on the front of the system, allowing the ability to stack materials horizontally
Disadvantages of Cantilever Racks
- Can require additional flooring or reinforcement
- Requires very wide aisle for material handling equipment access
- Cannot store pallets
- Load must be self-supporting
Multi-Tier Pallet Rack: Leverage Vertical Height
Multi-tier racking (also referred to as a pick module structure) offers an enhanced use of vertical space. They have different levels for manual picking and loading that are connected by stairs.
These systems are great for orders with small items, such as auto parts and fastener distributors and pharmaceutical companies.
Thanks to the multiple levels, multi-tiered pallet racks create higher density picking. Some means of conveying equipment are typically required to transport the picked goods out of the system.
Advantages of Multi-Tier Pallet Racking
- Maximum use of vertical warehouse space for order picking
- Flexible for different cartons or item sizes
- Direct access to SKUs without the use of industrial equipment
- Safe and enclosed to protect workers
Disadvantages of Multi-Tier Pallet Racking
Drive-In Pallet Racks: Ideal For Businesses With Limited Warehouse Space
Drive-in pallet rack is popular in warehouses because it allows businesses to store many goods in a small area for very dense storage. It’s perfect for warehouses with limited warehouse space since it eliminates aisles by having one shared entry and exit point.
The operator “drives-in,” to the system, and loads and unloads from one side of the system.
Because the operator drives into the system, there is greater interaction between the rack and the forklift resulting in an increased risk of damage and safety concerns.
Advantages of Drive-In Pallet Racks
- By removing aisles you increase storage space
Disadvantages of Drive-In Pallet Racks
- Utilizes LIFO (last-in-first-out storage) so older inventory can get stuck in the back of the racking system
- Low selectivity that may require multiple handling
- Since forklifts place and retrieve items within the racks, there is more risk of damage
- Pallet sizes must be the same size to fit in the lanes
- Pallet condition is very important as it provides the support of the load
- Risk of “honeycombing” with undisciplined storage put-away
- Challenging inventory management
Pallet Flow Racks: Take Advantage of Gravity
Pallet Flow Rack systems utilize common selective pallet rack components, with the addition of roller tracks.
One side of the pallet flow rack (also called gravity flow racks) is for loading, and the other end is for picking. Pallets are loaded into the back of the system and they roll to the front of the system by means of gravity rollers.
This gravity system increases storage capacity and enhances the storage and retrieval process, which reduces the workforce and labor required.
They are commonly seen in applications that have products with expiration dates due to the higher turnover rates these FIFO (first-in-first-out) pallet rack systems provide.
Advantages of Pallet Flow Racks
- It uses the FIFO method, preventing inventory from getting stuck in the back
- Quick and efficient inventory turnover
- Very high storage density with little lost space
- Reduces replenishment for picking (great for fast-moving SKUs)
Disadvantages of Pallet Flow Racks
- Pallets can become jammed if broken pieces get caught in the gravity rollers
- Reliant on pallets as the medium for movement
- Require maintenance on wheels and brakes
- One of the most expensive pallet racking systems
Push Back Pallet Racking: Ideal for Storage Density
Push-back pallet rack systems are perfect for warehouses that have a high volume of SKUs and that are looking for storage density.
The racks use pallets that are stored on inclined rails with free-rolling carts. As pallets are loaded into the system, the loading pallet pushes or stores pallets toward the back of the system, with the new pallet assuming the storage location of the old. When loads are removed from the front of the rack, the next pallet rolls to the front position.
This type of rack is ideal for storing frequently accessed products since items utilize gravity to move the next group of materials forward.
Since everything can be accessed from the front of the aisle, push-back racks use the LIFO method and require fewer pick aisles.
Advantages of Push Back Pallet Racking
- High-density storage
- Custom designed for your pallet sizes
- Decreased labor costs
- Forklifts do not enter the rack structure, limiting damage
- Increased Pallet Access
Disadvantages of Push-Back Pallet Racking
- Limited to 5 or 6 pallets deep
- Reliance on the load to push the other loads
- Possible product damage when carts slide forward
- Loss of some vertical space due to the slope of the rails
- Higher costs and more frequent maintenance – due to the number of wheels, carts, and bearings used
Other Types of Dynamic Racking
Many other types of dynamic racking can be customized to fit the needs of your warehouse.
These include pallet flow racks, light shelving, and mezzanine structures.

Your Guide to the Best Pallet Racking Systems for Different ...
As more companies look for ways to create additional space in their warehouses to meet demand and boost productivity, they need well-designed pallet racks. Pallet racking systems can maximize the capacity and efficiency of a warehouse. With the right storage racking solution, distribution managers can increase their throughput, improve productivity, and ensure their product is safely stored.
What Is a Pallet Racking System?
A pallet racking system is a type of warehouse storage or shelving that's specifically designed to handle products on pallets. By using a pallet rack system, you can take advantage of underutilized vertical space in the warehouse as pallets filled with inventory are stacked horizontally in vertical sections.
Warehouses and distribution centers often use pallet racks to maximize the use of their space and increase the warehouse’s efficiency in picking stocked items. With the help of forklifts, order pickers, and other material handling equipment, these materials can be loaded and unloaded from the racking shelves. The right racking system allows a warehouse or distribution center to organize its inventory, allowing products to be swiftly picked and sent to customers.
Types of Pallet Racking
While there are many types of pallet racking systems, the following are the most common.
Selective Racking
Selective racking is ideal if a warehouse has a low number of pallets per SKU. Many companies choose this pallet racking system since it supports first-in, first-out (FIFO) access to any pallet. Typically, selective racking consists of metal shelving designed to fit pallets. These pallets can be quickly racked and removed with a forklift. Warehouses that use selective racking typically have a space utilization rate of 90%.
Narrow Aisle and Very Narrow Aisle Racking
Narrow aisle and very narrow aisle (VNA) pallet rack systems are ideal for warehouses needing to make use of every bit of space, as the racks are placed much closer together with narrower than average aisles. These narrow aisle and VNA racking systems require specific types of lift trucks to safely and efficiently operate in the rows. Turret trucks or articulated forklifts are used to pick up pallets from the rack picking and deposit (P&D) stations at the end of the bay. These forklifts then store the pallets into the racking.
High Bay Pallet Racking
High bay racks are ideal for creating additional vertical storage space and storing large quantities of high-throughput goods. Pallets are placed in a single or double deep system. This automatically controlled system can be served by racking cranes that operate with floor-mounted rails. High bay pallet racking systems are a good choice for those who want convenient access to all pallets in their warehouses.
Double-Deep Racking
Double-deep racking systems can support first-in, last-out (FILO) access in a warehouse and allow product to be stored two pallets deep. They are a great solution for spaces with more pallets per SKU, providing up to 90% storage utilization. A double deep pallet racking system is not the best choice for a warehouse that regularly needs access to pallets.
Push-Back Racking
A push-back pallet rack is another option for a warehouse that needs to increase storage density. It is best suited for warehouses with more pallets per SKU, where it can boost storage utilization by 90%. When the forklift loads a new pallet, it pushes the last pallet toward the back. Often, this type of racking holds two pallets, but these systems can be customized to fit up to six pallets deep.
Like double-deep pallet racks, this system can support FILO processes and is typically used for whole pallet storage only. Forklift drivers must be careful with the pallets during the unloading and loading stages to ensure pallets are stored in the correct order and at proper alignments.
Pallet Flow Racking
Pallet flow rack systems work in a similar way to push-back pallet racks. However, these systems employ rollers and gravity. Instead of loading the rack in the front, these systems load from the back. The pallet flow racking system is built at a slight angle, allowing the products to be placed in the back and pushed forward until they reach the front of the pallet. A pallet flow rack system is an excellent option for first-in, first-out (FIFO) product arrangements.
Drive-In and Drive-Through Racking
The drive-in and drive-through pallet rack is great for warehouses with high storage density requirements. Instead of horizontal shelves, drive-in racks are designed in a lane with rails on both sides. In many cases, these racking systems can store up to 12 pallets deep or seven pallets high.
Mobile Racking
Warehouses needing a large amount of storage should consider a mobile pallet rack. It can support around 90% storage utilization with only modest pallet movement. A single aisle will be open at a time, allowing forklift drivers to access the pallets. The racks are built on rails in the floor and can be adjusted as needed. Many warehouses use mobile racking for cool or cold storage.
Cantilever Racking
A cantilever rack is a simple system. Rather than having shelves for holding pallets, this system has a base that supports arms to hold long or oversized products like pipes or lumber. A cantilever racking system can be used in warehouses with or without pallets, and managers can customize the system to hold materials of any size.
Pallet Shuttle Racking
This type of warehouse racking system is also called a deep lane pallet rack system, and it is an excellent option for warehouses with a high volume of products. Many warehouses use pallet shuttlepallet shuttle racking systems to increase space utilization. All pallets can be accessed with a remote-controlled mobile shuttle, allowing companies to maximize efficiency and storage.
