Timber merchants, steel stockholders, and fabrication yards across Northern Ireland have the same storage problem. How do long awkward-shaped materials stay off the ground, organised, and safe to pick, while wasting half your yard on aisle space? Cantilever racking only provides that solution if the arm length, spacing, and column layout are correctly specified for what you store. If you get this wrong, you pay for capacity you never use or end up with a system that cannot hold the loads coming off the delivery lorries.

One of the first choices is single-sided or double-sided arms. Fixed single-sided runs against a wall suit sites where access is from one side, such as a builder’s merchant with a loading bay that’s against a boundary fence. For open yards or bays where a forklift or telehandler can approach from either side, double-sided columns with arms extending from either side provide much better floor space utilisation. For most manufacturers and merchants who store large volumes of timber, box section steel, or plastic pipes, double-sided racking provides significantly higher storage per square meter of concrete, which is a big factor given the high cost of land and covered space.

Instead of using a catalog measurement, your arm length and spacing should be measured against your actual stock. It is a safety risk to have unsupported overhangs and to have timber and steel lengths left unsupported. Having arms set further away can create dead space vertically and limit the amount of levels you can have under a ceiling height. Before quoting, an accurate site visit should be done, where lengths, bundle weights, and turnover numbers are measured (not guessed). Real-world handling should also be considered when load ratings are set, including how bundles are lifted and set down, and not just the material’s static weight. For a closer look at load capacities and arm configurations, this guide to cantilever racking is a useful reference when planning a new installation.

Many buyers under estimate how much the base type matters. Northern Ireland’s outdoor cantilever racking will need a galvanised finish on the painted steel for Northern Ireland’s rainfall and salt-laden coastal air, as it will corrode quickly when the coating is damaged from contact with a forklift or falling stock. Column bases must also be placed on an adequately deep, level concrete pad that is prepared properly, as cantilever towers rely on unevenly loaded arms to resist tipping and asymmetrically carry a lot of load.

During the design phase, it is important to get aisle width correct, as the cost to fix it later can be far greater than the cost to do it right initially. Usage of reach trucks and telehandlers with longer wheelbases will further complicate optimal future configurations to maximise yard design. It is decidedly more economical to identify slightly expanded aisle widths than to design for relocate entire cantilever row runs.

While inspection and maintenance may be required on other types of rack systems, it is equally important in conjunction with simpler looking cantilever systems. Regular inspection for loose base fixing’s, column impact damage, and bent arms is required to ensure compromised columns do not create an uneven loaded instability. In a busy yard this creates a genuine safety hazard.

When designing your warehouse, you need to think about how your cantilever racking will integrate with your overall storage solution, especially where long-load storage is integrated with palletised stock or adjacent mezzanine floors. Place cantilever runs so delivery vehicles can access them directly without having to cross heavy forklift traffic, as this will minimise yard congestion and minimise collision risk during busy delivery times. Where a site is likely to broaden its product range over time, leaving an empty bay or two at the design stage is a small cost to avoid a much bigger disruption later to do the reconfiguration.

Starting with what you actually need to store, how it flows through the yard, how you will use the site in the years beyond the current design, and not with an arbitrary arm and column combo is the right way to specify cantilever racking. This means measuring real stock and real handling equipment during a site visit, followed by layouts designed with galvanised steel in locations where corrosion is an issue. This will provide a system that endures while keeping stock, staff, and forklift operators safe.
