Pallet Racking Explained: Information About Commercial Warehouse Racking

What is Pallet Racking?

Pallet racking is a material handling storage system designed to store pallets, which are horizontal platforms used to support goods. These systems are commonly used in warehouses and industrial settings to maximise storage space and facilitate the efficient movement of goods.

Pallet racking systems have evolved significantly over the years, incorporating advanced materials and engineering principles to enhance load capacity and safety.

How Pallet Racking Works

Pallet racking systems operate on the fundamental principle of loading pallets onto storage racks and retrieving them as needed. Forklifts are essential tools in this process, used to move pallets onto the racks, transfer them to different areas within the warehouse, and remove pallets when they are no longer required.

A standard warehouse racking system includes racks with aisles between them for easy access. However, to achieve higher storage density, various systems place racks higher, closer together, or in configurations that allow multiple pallets to be loaded and unloaded from a single access point.

Different racking systems cater to different operational needs. Some are designed for first-in, first-out (FIFO) processing, ensuring that the oldest inventory is used first. Others are better suited for first-in, last-out (FILO) storage, where the most recently stored items are accessed first. There are also dynamic systems, which can be either gravity-powered or self-powered, allowing pallets to automatically move through the storage process.

The main components of pallet racking systems include:

• Uprights: Vertical frames that support the racking structure.
• Beams: Horizontal supports that hold the pallets.
• Wire Decking: Mesh grids placed on beams to support the pallets and provide additional safety.
• Accessories: Components such as spacers, safety bars, and column protectors that enhance the functionality and safety of the racking system.

Uses & Benefits Of Pallet Racking In Warehouses

You will find pallet racking systems in almost every commercial warehouse in the world that used to store, manage and handle goods, and for good reason. Pallet racking systems offer a range of important benefits to warehouse operators:

Increased Storage Capacity
Pallet racking systems maximise the use of vertical space in your warehouse, allowing for a more efficient layout by stacking pallets high. This results in an increase in your overall storage capacity without the need to expand the footprint of your facility.

Efficiency & Accessibility
A well-organised pallet racking setup enables easy access to every pallet, which streamlines the process of storing and retrieving goods. This accessibility significantly speeds up operations and can reduce costs by minimising the time spent on handling products.

Scalability & Flexibility
Modern pallet racking systems are designed to be adaptable, accommodating changes in the volume or type of goods stored. As your business grows or evolves, your racking can be adjusted or expanded to meet new demands without requiring a complete overhaul of the existing system.

Inventory Management
With everything neatly organised and easily accessible, inventory tracking becomes more manageable. Pallet racking systems facilitate better inventory control, allowing businesses to implement just-in-time inventory practices which reduce the holding costs of inventory and can improve order fulfilment times.

Enhanced Safety
Safety in the workplace is paramount, and a well-designed pallet racking system contributes significantly to a safer warehouse. By reducing clutter and ensuring that heavy items are securely stored at appropriate heights, the risk of accidents and damage to goods is minimised.

Cost Savings
By optimising space and improving operational efficiency, pallet racking systems can lead to considerable cost savings. These savings come from reduced property costs (by making better use of existing space), lower labour costs, and minimised product damage.

Customisation
Pallet racking systems can be custom-designed to accommodate specific items, weight capacities, and warehouse layouts. This tailored approach ensures that your storage solution is perfectly aligned with your operational requirements.

What To Consider When Choosing Pallet Racking

When selecting a pallet racking system, there are a range of factors that need to be considered to ensure the solution meets your specific requirements.

Consider the load capacity and weight distribution to ensure the system can safely support the weight of the stored goods. It's essential to choose a racking system that fits within the available warehouse layout and space constraints, including both the floor space and the building's height.

The type of goods stored is also fundamental to selecting the best racking solution for any space. Take into account the size, weight, and nature of the items, as well as the need for easy access to stock for picking and rotation. Future expansion plans should also be considered; select a system that can be easily expanded or reconfigured to accommodate growth or changes in inventory needs.

Consider your warehouse workflow and processes. Think about the speed at which goods need to enter and leave the warehouse and the type of handling equipment that will be used.

What Kind Of Pallet Racking Do I Need?

There are various types of pallet racking systems and configurations available, each designed to meet specific storage needs and operational requirements. It’s important to understand the differences between types of pallet racking in order to choose the most suitable solution for your warehouse.

Selective Pallet Racking: This is the most common type of racking system, allowing direct access to each pallet. It is ideal for warehouses with a wide variety of products and where stock rotation is important. For example, a retail distribution centre might use selective pallet racking to store and easily access different types of merchandise.

Double Deep Racking: This system stores two pallets deep, increasing storage density and requiresspecialised forklifts with extendable forks. A food and beverage warehouse might use double deep racking to store large quantities of the same product while minimising aisle space.

Narrow Aisle Racking: This system is designed to maximise storage capacity by reducing the width of the aisles between racks. Narrow aisle racking requires specialised forklifts to operate in tighter spaces. A high-density storage warehouse, such as those used by logistics companies, might use narrow aisle racking to increase the number of pallet positions within the same footprint.

Drive-In and Drive-Through Racking: This type of racking allows forklifts to enter the racking system to pick up or deposit pallets. Drive-in racking is suitable for last-in, first-out (LIFO) inventory management, while drive-through racking supports FIFO. A cold storage facility might use drive-in racking to store frozen goods that have a longer shelf life.

Push-Back Racking: In this system, pallets are placed on nested carts that move along inclined rails. Push back racking stores goods multiple pallets deep and operates on a LIFO basis. A manufacturer of packaged goods might use push-back racking to store products with a high turnover rate and limited SKU variety.

Pallet Flow Racking: This system uses gravity to move pallets on inclined rollers, facilitating FIFO inventory management. A distribution centre handling perishable items, such as dairy or produce, might use flow racking to ensure that older stock is used first.

Cantilever Racking: Ideal for storing long, bulky items such as lumber, pipes, or steel rods, cantilever racking uses a unique design with improved access necessary to deposit and retrieve these items. A building materials supplier might use cantilever racking to organise and store different lengths and types of materials efficiently.

Shuttle Racking: These racks are mounted on mobile bases that move along tracks, maximising space utilisation by eliminating the need for multiple fixed aisles. Shuttle racking can be used to move whole pallets into and out of storage, and helps to improve efficiency with less input from personnel.
