How to Balance High Density Storage with Operational Flexibility

Warehouse operations must achieve a balance between high density storage and operational flexibility if they are to work efficiently and cost-effectively while delivering high levels of customer satisfaction and repeat business.

Why the design of a warehouse matters

There is a sweet spot in terms of warehouse capacity, where the physical space available is maximised without compromising the ability of warehouse personnel to locate and fulfil orders quickly. Where this balance is achieved, warehouse operations thrive, with high density storage extending vertically and horizontally to accommodate maximum stock levels.

Should businesses fail to realise the potential of their premises and hold less stock than they are capable of accommodating, they are losing money, as although workers are easily able to account for inventory, locate it and fulfil orders, they could potentially operate from smaller, less expensive premises while achieving the same return.

When businesses push the limits of what their premises can accommodate, they can create friction in their processes, with workers less able to manage inventory and adapt to changes in market dynamics.

How the right pallet racking design supports business objectives

Choosing the right racking and storage systems is pivotal to the success of warehouse operations. Businesses must consider the physical space available to them, the weight and dimensions of the products they will store, the manner in which those products will be lifted and moved and the speed with which orders must be fulfilled in order to select an appropriate storage solution that maximises operational flexibility while delivering high density storage.

Different warehouse storage solutions

Some of the most common warehouse storage solutions include:

• Adjustable pallet racking: This versatile adjustable racking solution enables beam levels to be repositioned as required to adapt to different sized pallets, allowing warehouse operations to reconfigure their storage solutions as their inventories and requirements evolve.

• Push-back racking: Push-back systems maximise the available space in a warehouse by eliminating unnecessary aisles and storing multiple pallets one in front of the other, operating on a last-in, first-out principle. This is a popular storage solution for businesses with high product turnover rates.

• Drive-in racking: Similar to push-back racking, drive-in racking aims to minimise the number of aisles in the warehouse by placing pallets close together. While this solution allows for storage of large volumes of pallets, access to specific individual pallets is limited, so this solution is unsuitable for businesses where selectivity is important.

• Tiered shelving systems: As not all warehouses are exclusively used for palletised goods, tiered shelving allows for the creation of multiple walkable floor levels, making best use of the vertical axis within the environment and keeping products easily accessible without the need for specialist equipment.

Industry best practice for warehouse design

Industry bodies such as the UK Warehousing Association (UKWA) and the Storage Equipment Manufacturers' Association Ltd (SEMA) have issued best practice guidance on warehouse and pallet racking design, installation, and maintenance to enhance operational capacity while prioritising worker safety.

These best practice guides cover a number of elements, including tailoring the warehouse design based on the characteristics of the products they stock, the way in which those products are picked and the likely throughput patterns, making recommendations that will ensure legal compliance without compromising productivity.

By designing for functionality and safety, warehouse operations can be zoned to satisfy operational needs and safety instructions tailored to those individual zones. This means that businesses can employ different processes and technologies within each zone as appropriate in achieving their KPIs without putting workers at risk.

The link between maintenance, compliance and safety

For warehouse operations to be productive and safe, it is essential to design for success, ensure that all storage solutions are professionally installed and follow the manufacturer's recommended maintenance schedule. On-site personnel should receive adequate health and safety training to allow them to discharge their duties safely and effectively and to report any defects or deficiencies in the organisation's processes or equipment such that they can be remedied at the earliest possible opportunity.

Because there is not a one size fits all solution to warehouse design, it is essential that warehouse operators carefully consider their needs and consult with independent industry experts where appropriate. This approach helps them develop solutions that maximise capacity while allowing for flexibility and efficiency, enabling them to meet logistical challenges and take advantage of new opportunities.
