Selective Storage Racking Vs. Push Back Racking: What’s The Difference?

Push back racking and selective storage racking are two popular options for warehouse storage systems. Both have their own unique strengths and weaknesses, making them suitable for different types of businesses and storage needs. In this article, we will explore the key differences between selective storage racking and push back racking to help you determine which option is best for your warehouse.

Overview of Selective Storage Racking

Selective storage racking is a type of storage system that allows for direct access to every pallet stored. This means that each pallet can be easily retrieved without having to move others out of the way. Selective storage racking is ideal for warehouses that need quick and easy access to their inventory. This type of racking system is also beneficial for businesses that have a wide variety of SKUs and need to be able to pick a small number of items from a large inventory.

Selective storage racking is typically designed with upright frames and horizontal beams that can support pallet loads. These racks can be easily adjusted to accommodate different pallet sizes and weights. Some common types of selective storage racking include pallet flow racks, drive-in racks, and push back racks.

One of the main advantages of selective storage racking is its versatility. It can be configured to fit virtually any warehouse space and can accommodate various types of inventory. Selective storage racking is also relatively easy to install and maintain, making it a cost-effective option for many businesses.

However, selective storage racking is not without its drawbacks. Since each pallet is stored individually, this type of racking system requires more aisle space compared to other systems. This can reduce overall storage density in the warehouse and may not be the most efficient option for businesses with limited space.

Overview of Push Back Racking

Push back racking is a type of storage system that utilizes a series of nested carts to store pallets. When a new pallet is loaded onto the system, it pushes the existing pallets back along the rails, hence the name "push back racking." This allows for high-density storage while still providing access to multiple SKUs.

One of the main advantages of push back racking is its ability to maximize storage density. By storing pallets in a last-in, first-out (LIFO) manner, push back racking can make the most of available warehouse space. This can be especially beneficial for businesses with limited space or a need to store a large amount of inventory.

Another benefit of push back racking is its efficiency. Since pallets can be stored several deep, fewer aisles are needed to access the same amount of inventory compared to selective storage racking. This can reduce the amount of time it takes to pick items and increase overall warehouse productivity.

However, push back racking may not be the best option for all businesses. One potential drawback is the lack of selectivity in accessing inventory. Since pallets are stored in a LIFO manner, it can be challenging to access specific items without moving other pallets out of the way. This may not be ideal for businesses that need to pick a large number of SKUs on a regular basis.

Key Differences Between Selective Storage Racking and Push Back Racking

While selective storage racking and push back racking both offer unique benefits, there are several key differences between the two storage systems that should be taken into consideration when choosing the right option for your warehouse.

Selectivity: One of the main differences between selective storage racking and push back racking is the level of selectivity they offer. Selective storage racking allows for direct access to each pallet stored, making it easy to retrieve specific items quickly. On the other hand, push back racking stores pallets in a LIFO manner, which can make it more challenging to access specific items without moving others out of the way.

Storage Density: Another key difference between the two storage systems is storage density. Push back racking is designed to maximize storage density by storing pallets several deep. This can be beneficial for businesses with limited space or a need to store a large amount of inventory. Selective storage racking, on the other hand, may not offer the same level of storage density since each pallet is stored individually.

Efficiency: Efficiency is another factor to consider when comparing selective storage racking and push back racking. Push back racking can be more efficient in terms of space utilization and picking times since fewer aisles are needed to access the same amount of inventory compared to selective storage racking. However, selective storage racking may offer better efficiency in terms of selectivity and quick access to specific items.

Cost: The cost of installation and maintenance is another important consideration when choosing between selective storage racking and push back racking. Selective storage racking is generally more cost-effective to install and maintain since it requires less equipment and can be easily adjusted to accommodate different inventory sizes. Push back racking, on the other hand, may require more upfront investment and ongoing maintenance due to its nested cart system.

Versatility: When it comes to versatility, selective storage racking has the upper hand. This type of racking system can be configured to fit virtually any warehouse space and can accommodate various types of inventory. Push back racking, while efficient in terms of storage density, may not offer the same level of versatility since it is designed for high-density storage.

In conclusion, both selective storage racking and push back racking have their own unique strengths and weaknesses. The best option for your warehouse will depend on your specific storage needs, available space, and budget. Selective storage racking may be ideal for businesses that need quick access to a wide variety of SKUs, while push back racking may be better suited for those looking to maximize storage density. Consider the key differences between the two storage systems outlined in this article to make an informed decision for your warehouse.

In summary, selective storage racking and push back racking are two popular options for warehouse storage systems, each offering unique advantages and drawbacks. Selective storage racking provides direct access to each pallet stored and is versatile and cost-effective. In contrast, push back racking maximizes storage density and efficiency but may lack selectivity in accessing inventory. When choosing between the two systems, consider factors such as selectivity, storage density, efficiency, cost, and versatility to determine the best option for your warehouse needs.
