Technical Guide to Cantilever Racking Systems
The Runda Cantilever Racking System is the definitive solution for storage challenges that traditional pallet racks cannot solve. Designed specifically for long, bulky, or oddly shaped items, our system eliminates the front-pillar obstructions that hinder warehouse throughput. Whether you are managing a timber yard, a steel distribution center, or a manufacturing facility, cantilever racking provides the 100% horizontal accessibility required for efficient, damage-free operations.
Industry Context: Solving the Long-Load Bottleneck
In traditional racking, the vertical uprights dictate the maximum width of a stored item. For industries dealing with 6-meter pipes, 12-meter timber bundles, or oversized furniture, standard racking leads to wasted space and high risk of collision damage. Forklift operators are forced to navigate tight tolerances, leading to slower cycle times and increased labor costs.
The cantilever system completely reimagines the storage interface. By supporting the load from the rear column and projecting arms forward, the system creates a continuous storage shelf with no horizontal breaks. This unrestricted access allows for the storage of items of any length and significantly simplifies the loading and unloading process. In today’s high-velocity industrial environment, the cantilever rack is not just a storage tool—it is a critical driver of operational speed and safety.
Structural Engineering: Engineering Stability Without Front Support
The primary engineering challenge of a cantilever system is managing the immense leverage (moment) exerted on the rear columns and the base. Runda’s engineering team utilizes advanced FEA (Finite Element Analysis) to ensure that every component can withstand extreme static and dynamic loads.
1. Column and Base Synergy: The vertical column and the horizontal base form the structural foundation. We utilize a high-tensile bolted connection using Grade 8.8 structural fasteners. This allows for a slight degree of controlled flexibility which is superior to rigid welding in seismic events or high-impact environments.
2. I-Beam vs. Roll-Formed Profiles: For light-duty applications (up to 500kg per arm), we offer high-precision roll-formed C-sections. For heavy-duty industrial use, we utilize hot-rolled I-beams (H-sections). These structural steel profiles offer superior resistance to twisting and buckling, allowing our systems to reach heights of 12 meters while supporting 2500kg per arm.
3. Pivot Arm Technology: The most common point of failure in cantilever racks is the arm connection. Runda utilizes a pivot-pin design. Unlike fixed-bolt systems, the pivot pin allows the arm to move slightly when struck by a forklift. This “deflection without damage” philosophy saves our clients thousands in annual repair costs and prevents catastrophic rack collapse.
Material Science: Durability in Harsh Environments
Industrial storage systems are often subjected to moisture, chemical exposure, and temperature extremes. Runda selects materials that ensure a 25-year structural lifespan.
Q345B Structural Steel: We primarily utilize Q345B steel for our heavy-duty columns and arms. This low-alloy, high-strength steel provides a higher yield point than standard Q235, allowing for slimmer profiles that support greater weights, maximizing your storage-to-steel ratio.
Protective Coatings for Every Environment:
- Electrostatic Epoxy Powder: Our standard indoor finish, featuring a 7-stage pre-treatment process for maximum scratch resistance and a professional aesthetic.
- Hot-Dip Galvanization: For outdoor timber yards or metal wholesalers, we submerge the steel in a 450 degree Celsius zinc bath. This creates a metallurgical bond that provides self-healing properties and 30+ years of rust protection.
Operational Efficiency: Reducing Damage and Cycle Times
Efficiency in a long-load warehouse is measured by the “touch count” and the “damage rate.” The cantilever system is designed to minimize both.
1. 100% Selectivity: Every item in a cantilever rack is accessible at all times. There is no need to move “front” items to reach “back” items, as is often required in floor-stacking. This reduces forklift travel time and eliminates the risk of damage during reshuffling.
2. Compatibility with Side-Loaders: Cantilever racks are the perfect partner for side-loading forklifts and multi-directional reach trucks. By allowing these vehicles to operate in aisles as narrow as 2.5 meters, we help clients increase their storage density by up to 40% compared to standard forklift aisles.
3. Adaptive Inventory Levels: Inventory mixes change. Our columns are precision-punched with 75mm hole centers, allowing you to re-space arms in minutes. This adaptability ensures that your rack grows and changes with your business.
Safety & Compliance: Engineering for Peace of Mind
Safety is paramount when storing heavy, long-span loads above head height. Runda’s cantilever systems are engineered to exceed all international safety benchmarks.
Compliance Standards:
- FEM 10.2.09: The European code for the design of cantilever racking.
- AS4084-2012: Steel storage racking standards.
- RMI ANSI MH16.1: The American standard for industrial steel storage racks.
Key Safety Features:
- Arm Deflection Limits: Our arms are engineered to have a maximum upward camber when unloaded, ensuring that they become perfectly level when fully loaded, preventing the “sliding-off” effect.
- Removable Pipe Stops: Every arm includes a pre-drilled hole for 100mm to 200mm vertical stops, essential for cylindrical inventory.
- Seismic Bracing Sets: Custom-designed X-bracing provides the lateral rigidity needed to survive significant seismic events.
Installation & Scalability: A System That Grows With You
Runda’s modular design philosophy ensures that your initial investment is never obsolete.
1. Single-to-Double Conversion: Many of our single-sided columns can be converted to double-sided in the future by simply adding arms and base extensions, doubling your storage capacity without requiring new vertical structures.
2. Rapid On-Site Assembly: Our components are manufactured to such tight tolerances that on-site modification is never required. The system is entirely “bolt-together,” reducing installation time by 50% compared to welded systems.
3. Integrated Roof Systems: Transform your outdoor cantilever rack into a complete storage building. Our heavy-duty roof brackets support corrugated steel sheeting, providing a cost-effective alternative to a full warehouse building for timber and construction materials.

Project FAQ
Q: Are the arms easily damaged by forklifts during loading?
A: Our patented pivot arms are secured with heavy-duty pins rather than rigid bolts. This allows the arm to swing upwards and outwards upon impact from a forklift or load, significantly reducing the risk of structural failure and protecting the inventory from crushing.
Q: What is the maximum item length that can be stored?
A: There is no theoretical limit to the length of items stored. By increasing the number of vertical columns and adjusting the spacing between them, you can support everything from 2-meter steel bars to 20-meter industrial pipes or timber bundles.
Q: Can cantilever racks be installed outdoors?
A: Yes. For outdoor applications, we recommend our hot-dip galvanized finish, which provides superior protection against corrosion. We also offer roof-system attachments that can be bolted directly to the top of the columns to protect inventory from rain and UV exposure.
Q: How do we prevent items from rolling off the arms?
A: Every Runda cantilever arm can be fitted with removable end-stops or integrated 'pipe-stops.' These vertical barriers are essential for storing cylindrical items like PVC piping, metal conduits, or carpet rolls.
Q: What is the difference between I-beam and C-section cantilever racks?
A: C-section racks are made from roll-formed steel and are ideal for light to medium-duty applications. I-beam (structural) cantilever racks are made from hot-rolled wide-flange beams and are designed for extreme heavy-duty loads, such as steel coils or heavy machinery components.
Q: Is a specialized forklift required for cantilever racking?
A: While standard forklifts can be used, side-loaders or multi-directional reach trucks are highly recommended for cantilever systems storing long goods. These specialized vehicles allow for narrower aisles and safer handling of oversized loads.
Q: How is seismic stability managed in high-bay cantilever systems?
A: We utilize heavy-duty vertical and horizontal X-bracing between columns to ensure longitudinal stability. The base-to-column connection is engineered with high-tensile Grade 8.8 bolts, and floor anchors are specified based on local seismic zone requirements.
Q: What are the maintenance requirements for cantilever racks?
A: We recommend annual inspections to check for arm deflection, plumbness of columns, and tightness of floor anchors. Pivot pins should be checked for wear, and any arms showing permanent deformation beyond 0.5% of their length should be replaced.
