What is Cantilever Racking?
Cantilever racking is a specialised storage system designed to store long or irregular loads using vertical columns and outward-projecting arms. Unlike pallet racking, cantilever systems provide unobstructed access to the load, making them ideal for timber merchants, steel stockists, building supplies and yard storage.
What Types Of Cantilever Racking Do You Offer?
Conventional Cantilever
The most commonly used system and is designed to accommodate long length products. We offer either single-sided or double-sided options dependent upon your specific storage needs.
Free-Path Cantilever
Consists of rows of racking which are adjacent to each other, separated by an aisle. It enables your handling equipment to travel the length of the aisle without any guidance.
Guided-Aisle Cantilever
Provides a space-saving solution and maximises the use of your floor space which means it is ideal for warehouses which are limited by space. Runs are positioned closer together and can be accessed by specialist trucks guided by the guide-rail.
Internal & External Systems
We design our cantilever racking to fit your space perfectly, whether for indoor use or outdoor applications. For long-term external storage, we also offer durable, weatherproof galvanized finishes.

Cantilever Racking Features
Column
Punched at every 76 mm for maximum flexibility for accommodating different load heights. Columns are punched double sided as standard to allow single sided racks to be easily converted to double sided racks if and when required in the future.
Base
Bolted as standard on all stock racks which allows simple changeover from single to double sided and vice versa. Full width base end plates minimise damage to tyres on handling equipment.
Arms
Tapered open section arm design maximises clearances when loading and unloading.
Brace Frames
Cross braced bolted design gives good rigidity to minimise sway during loading/unloading operations.
Arm Connector Pins
Tailored design allows transmission of load from arm into column. Uniquely designed to allow rapid fitting and removal for quick arm relocation.
Readily Available
