Types of warehouse racking systems
Different racking systems are essential for optimising storage and enhancing efficiency in a warehouse. Each type of racking offers unique benefits, depending on the specific needs for capacity and accessibility.

Selective pallet racking
Selective pallet racking is one of the most common systems. It allows direct access to each pallet, providing flexibility and accessibility. This system uses vertical space effectively, making it suitable for varied pallet sizes and weights.

It’s ideal for warehouses that store diverse products. Operators often use forklifts to place and retrieve pallets, ensuring quick and easy inventory management.

Drive-in and Drive-through racking
Drive-in and Drive-through racking systems are for high-density storage. Drive-in racks operate on a last-in, first-out (LIFO) principle, where forklifts enter the rack from one end to load and unload.

Conversely, drive-through racking allows access from both ends, following a first-in, first-out (FIFO) system.

These systems maximise storage capacity by reducing aisle space, making them suitable for bulk storage. They are ideal for warehouses with products that don’t require quick rotation.

Pallet flow racking
Pallet flow racking, or dynamic or gravity flow racking, uses inclined rails and rollers to move pallets automatically. This system is a FIFO solution, ensuring high stock rotation and efficient handling.

It’s perfect for environments requiring high-volume throughput. Pallets move smoothly from the loading to the unloading end, making it easier to manage expiry-dated products.

The design effectively reduces handling time and increases storage density by utilising vertical space.

Cantilever racking
Cantilever racking stores long, bulky items. It uses arms extending from a central column to support loads without obstructing the floor space beneath.

This system provides easy access and flexibility for storing materials like lumber, pipes and sheet metal.

Cantilever racking is adjustable, allowing the storage of items with different lengths and weights. The open design enables forklifts to quickly load and unload items, making it a versatile choice for warehouses handling oversized materials.


Design and layout considerations
Effective warehouse design and layout can significantly improve storage efficiency, accessibility and workflow. This section covers key aspects to consider when designing a warehouse racking layout.

Maximising storage space
To maximise storage space, it is crucial to select the right racking system based on the warehouse’s specific needs. Inventory size, weight, and turnover rates should guide these choices.

For instance, pallet racking systems are ideal for storing single items and palletised loads because they leverage vertical space. However, racks must be placed strategically to ensure the system’s efficiency.

Proper planning can significantly improve space utilisation so you can store more products without expanding the warehouse footprint.

Aisle width and forklift access
Aisle width is a critical factor in warehouse design. It’s essential to balance between storage space and accessibility.

Narrow aisles can increase storage density but may restrict forklift manoeuvrability. Conversely, adequate aisle width ensures efficient forklift movement and operator safety. Standard aisle widths range from 12 to 14 feet for conventional forklifts.

Proper aisle planning also facilitates quicker access to products, reducing retrieval times and improving overall efficiency in warehouse operations.

Height utilisation and vertical space
Using vertical space efficiently can significantly boost storage capacity.

Use high-reaching racking systems that allow stacking products in tiers. Pair height utilisation with proper safety measures, such as secure shelving and pallet supports. It is vital to consider the height of the warehouse ceiling and the reach capabilities of forklifts.

Implementing these strategies can turn unused air space into productive storage areas, thus maximising the warehouse’s storage potential without needing floor expansion.


Racking system installation and safety
Proper installation and strict safety protocols are crucial for effectively and securely using warehouse racking systems. These measures help ensure that the storage systems are durable and safe for everyday use.

Proper installation procedures
Installing a racking system involves various steps and requires attention to detail to ensure everything is secure and stable.

First, it’s essential to have an ergonomic warehouse design that supports efficient storage and material handling. Engineers and installers must evaluate the warehouse layout and tailor the racking setup to the specific needs.

High-quality materials like durable steel are essential for the racks. Proper bolt anchoring to the floor and correct assembly of racking components are critical for stability. Installers should follow manufacturer guidelines meticulously and use appropriate tools and safety equipment during installation.

Adequate spacing should be maintained between racks to allow easy access and manoeuvring of goods and prevent potential damage.

Safety precautions and protocols
Ensuring a safe warehouse environment starts with maintaining the structural integrity of racking systems.

Regular inspections are essential to identify any wear and tear or potential hazards. Warehouse managers should train staff on the appropriate loading techniques to avoid overloading racks, which can lead to structural failures. Strategic prevention measures, such as column protectors, can minimise damage and increase safety.

Keeping aisles clear is crucial to avoid accidents and not obstruct emergency exits.
