How to Choose the Right Cantilever Racking for Long or Bulky Loads

Storing long, awkward, or heavy items like timber, steel bar, pipe, or PVC conduit is one of the trickiest warehouse challenges, and standard pallet racking rarely does the job well. Cantilever racking solves this by removing front columns entirely, giving you open-access arms that support loads along their full length rather than boxing them into a bay.

Consider Your Load Type First

Timber and structural steel need wide arm spacing and higher weight ratings, while smaller items like pipe or conduit often benefit from closer-spaced arms and roll-formed uprights to stop stock rolling off. Matching arm length and spacing to what you're actually storing prevents both wasted space and overloading.

Single-Sided vs Double-Sided Racking

If your racking will sit against a wall or be accessed from a forklift on one side only, single-sided cantilever units make sense. Where you have aisle space on both sides, double-sided racking roughly doubles storage density for the same footprint, which matters a lot in a Dandenong South-sized warehouse where floor space carries a real cost.

Engineering Standards and Compliance

Cantilever racking actually falls outside the scope of AS 4084 (which governs structural steel pallet racking), so there's no single mandatory Australian standard covering it the way there is for pallet racking. That makes it even more important to work with a supplier who can confirm the engineering basis for their design in writing — load ratings, arm and column specifications, and relevant structural certification — so you have a paper trail if you're ever audited.

Outdoor vs Indoor Use

Timber yards and building suppliers often need cantilever racking outside, exposed to weather. Galvanised finishes cost more upfront but avoid the corrosion that eventually weakens arms and uprights in an uncovered yard.

Plan for Future Growth

Cantilever bases are usually straightforward to extend with additional arms or columns later, so it's worth discussing your likely stock growth with your supplier before locking in a fixed configuration.
