Which Storage Solution is Best for Your Warehouse?
In any warehouse, space is a precious commodity. Every square foot counts, and with the costs associated with storage, making the most of your available area is not just smart—it's essential. Enter pallet racking, a staple in warehouses and distribution centres designed to maximise both vertical and horizontal space. But with various racking systems available, how do you determine which one aligns best with your specific operational needs?
To make an informed choice, start by analysing your inventory dynamics. Consider the number of SKUs, their turnover rates, and any seasonal fluctuations that might impact storage requirements. Understanding how products flow from receiving to order fulfilment is also crucial.
Once you have a clear picture of your operations, you can explore your racking options. While conventional pallet racking is popular for its straightforward design and low cost, it may not always be the most efficient use of space compared to high-density alternatives like pallet flow racking. In this article, we’ll compare these two systems to help you find the right fit for your warehouse storage solutions.
What is Conventional Pallet Racking?
Conventional pallet racking is the backbone of many warehouse storage systems, providing a reliable and efficient way to store palletized goods. This system features rows of racks that create aisles for easy access by forklifts and other handling equipment. Each pallet is stored on horizontal beams, allowing for direct and selective access to every product.
The primary components of this racking system include uprights that form the vertical framework and beams that support the pallets. The design of conventional pallet racking is tailored to accommodate the dimensions and weight of the items being stored, optimizing space utilization while ensuring stability and safety.
Typically, conventional racking can be configured in single or double rows. Single rows are accessible from one side and are often placed along the perimeter of the warehouse. In contrast, double rows allow access from both sides, making them ideal for central storage areas. For increased capacity, two double rows can be combined, enabling deeper storage solutions but requiring specialized equipment to reach pallets at the back.
Advantages
100% selectivity
Low-cost storage racking
Ideal for low-volume, high-SKU inventory
Supports FIFO inventory rotation
Requires considerable space for aisles
Limited pallet density per square foot
Versatile for varying inventory specs
Adaptable for any warehouse climate: ambient, refrigerator, cold-storage
What is Pallet Flow Racking?
Pallet flow racking, often referred to as flow rack, is a dynamic storage solution that utilises gravity to facilitate the movement of pallets. This system employs a series of inclined lanes fitted with rollers or wheels, allowing pallets to glide smoothly from the loading end to the unloading end. This design not only maximises storage density but also streamlines the picking process, making it an ideal choice for warehouses with high inventory turnover.
The fundamental principle behind pallet flow racking is First-In, First-Out (FIFO) inventory management. As pallets are loaded at the back of the rack, they naturally roll forward to the front as items are picked. This ensures that older stock is accessed first, which is particularly beneficial for perishable goods or items with expiration dates.
Pallet flow racks can accommodate multiple pallets deep—often ranging from two to over twenty—allowing for efficient use of vertical space while minimising the need for wide aisles. The absence of intermediate aisles not only optimises storage capacity but also reduces forklift travel time, enhancing overall operational efficiency.
Advantages
Double the capacity vs. conventional pallet rack storage
More productive – less travel time between aisles
Lane depth 2- to 10-pallets deep
FIFO inventory rotation – ideal for dated goods
Higher cost per pallet position
Additional height required per level
Key Differences: Conventional Pallet Rack Vs Pallet Flow Racking
When it comes to optimising warehouse storage, understanding the distinctions between Conventional Pallet Racking and Pallet Flow Racking is essential. Each system offers unique features and benefits tailored to different operational needs. Let’s break down the key differences to help you make an informed decision.
Storage Density:
Conventional Pallet Racking: This system typically requires wider aisles for forklift access, which can limit overall storage capacity. While effective, it doesn’t maximise vertical space as efficiently as high-density systems.
Pallet Flow Racking: Designed for high-density storage, this system utilises gravity to allow pallets to flow from the loading side to the picking side. This results in a compact design that significantly increases storage density.
Inventory Management:
Conventional Pallet Racking: Often operates on a Last In, First Out (LIFO) basis, making it suitable for items that do not require strict rotation. This can lead to older stock being overlooked if not managed carefully.
Pallet Flow Racking: Utilises a First In, First Out (FIFO) method, ensuring that older inventory is picked first. This is particularly beneficial for perishable goods or items with expiration dates, enhancing stock rotation and reducing waste.
Accessibility:
Conventional Pallet Racking: Offers direct access to each pallet but requires more aisle space, which can limit the number of pallets stored within a given area.
Pallet Flow Racking: Provides efficient access as pallets automatically move forward when one is removed. This reduces the need for extensive aisles while maintaining easy access to all inventory.
Cost and Installation:
Conventional Pallet Racking: Generally has lower initial costs and simpler installation processes, making it a popular choice for many warehouses.
Pallet Flow Racking: While the upfront investment may be higher due to its complex design and components, the long-term savings from improved efficiency and reduced labour costs can offset this initial expense.
Flexibility and Scalability:
Conventional Pallet Racking: Offers moderate flexibility in terms of configuration but may require significant effort to adapt to changing inventory needs.
Pallet Flow Racking: Highly adaptable, allowing for retrofitting into existing systems. This makes it easier to scale operations as business needs evolve.

FAQ
What is the difference between pallet flow racking and drive-in racking?
Pallet flow racking uses gravity to move pallets through inclined lanes, while drive-in racking allows forklifts to enter the storage lanes directly.
How does FIFO inventory management impact warehouse efficiency?
FIFO ensures that older stock is used first, reducing waste and improving inventory turnover rates.
Can conventional racks be modified for FIFO inventory?
While some modifications can be made, conventional racks are not inherently designed for FIFO management like pallet flow systems are.
