In the world of industrial storage, few challenges compare to the safe and efficient organization of long, heavy, or irregularly shaped materials. Steel pipes, in particular, demand a storage system that goes beyond conventional pallet racking. Standard shelving units often fail to provide the necessary support, accessibility, or load distribution required for cylindrical or elongated products. This is where cantilever racking systems demonstrate their true engineering value. Herochu has developed a specialized solution for steel pipe warehouse storage using SS401 steel, a material known for its exceptional yield strength and resistance to structural fatigue. This article explores the technical specifications, operational benefits, and long-term cost efficiencies of the Herochu heavy-duty cantilever racking system designed specifically for steel pipe storage.

Structural Composition and Material Grade

The foundation of any reliable pipe storage rack lies in its material composition. Herochu utilizes SS401 structural steel, a grade that complies with international standards for heavy-load applications. SS401 offers a minimum yield strength of 400 MPa, making it significantly more resilient than standard mild steel options. This allows the rack to maintain dimensional stability even when supporting maximum loads of up to 5,000 kg per layer. The column profiles are cold-formed from 3.0 mm to 4.5 mm thick SS401 sheets, depending on the height and load requirements. Base plates are reinforced with gussets to distribute vertical loads evenly across the floor surface, reducing point-load stress on warehouse concrete slabs.

Cantilever Arm Design and Capacity

Each cantilever arm in the Herochu system is fabricated from a single continuous piece of SS401 steel, bent into a tapered profile that increases strength at the root where bending moments are highest. Standard arm lengths range from 550 mm to 800 mm, with custom extensions available up to 1,200 mm. The arms are rated for loads between 1,000 kg and 1,500 kg per arm, depending on length and spacing. A key safety feature is the pivot arm safety system, which prevents accidental dislodgement during crane loading or seismic events. Arms are coated in high-visibility orange powder coating, while the columns, bases, and bracing receive a durable galvanized finish. This color differentiation serves both aesthetic and safety purposes, as operators can quickly identify moving parts and load boundaries.

Column Heights and Storage Density

Herochu cantilever racks are engineered with column heights reaching up to 10,000 mm, allowing warehouses to maximize vertical airspace. When combined with overhead crane systems, these tall racks eliminate the need for wide forklift aisles. The standard column spacing is set at 1,200 mm on center, but this can be adjusted to accommodate specific pipe diameters. Each column section is punched with square holes at 75 mm increments, providing precise height adjustability for arm positioning. This modularity means a single column can support between three and five levels of arms, depending on pipe diameter and access requirements. For warehouses storing mixed pipe diameters, the adjustable arm height allows for reconfiguration without welding or cutting.

Roll-Out Cantilever Mechanism for Direct Access

One of the most innovative features of the Herochu steel pipe storage rack is the optional electrically driven roll-out mechanism. Unlike static cantilever racks that require cranes or forklifts to extract pipes from the front, the roll-out system allows each arm level to extend outward horizontally. This mechanism uses precision-ground bearings mounted on linear rails, with a travel distance equal to 80% of the arm length. Once extended, the arms lock into position using a spring-loaded pin system, giving operators full access to stored pipes from above or the side. This eliminates the need for deep-reach forklifts or multiple crane movements. The roll-out function can be manual for lighter loads or motorized for loads exceeding 2,000 kg per level. For heavy-duty applications, Herochu offers a synchronized electric drive that extends all arms on a given level simultaneously, reducing retrieval time by up to 60% compared to traditional cantilever systems.

Load Capacity Table and Customization Options

The following parameters represent standard configurations for Herochu roll-out cantilever racks, with full customization available for unique warehouse dimensions:

The “+1” in the number of layers indicates a dedicated top level for short offcuts or accessory storage. Arm nose deflectors are standard on all units to prevent pipe ends from snagging during loading. Colors are available in orange/blue or full galvanized for outdoor applications.

Durability and Maintenance Considerations

Warehouse environments expose steel racking to humidity, dust, and mechanical impacts from crane hooks and pipe ends. Herochu addresses these challenges through a three-stage corrosion protection process. First, all SS401 components are sandblasted to Sa 2.5 cleanliness. Second, a hot-dip galvanized coating of 85 microns is applied to columns and bases. Third, arms receive a polyester powder coating cured at 200°C. This combination provides resistance to red rust for over 1,000 hours in salt spray testing. For maintenance, the pivot arm safety system and roll-out bearings are designed for lubrication every 2,000 operating hours using standard lithium-based grease. Replacement arms or column protectors can be ordered individually, reducing downtime compared to welded racks that require complete unit replacement.

Conclusion

Herochu heavy-duty cantilever racking using SS401 steel offers a purpose-built solution for steel pipe warehouse storage. From its high-strength metallurgy and adjustable arm configurations to the advanced roll-out mechanism and corrosion-resistant finishes, every detail is engineered for industrial longevity. Warehouses dealing with steel pipes, structural sections, or any long product will find this system reduces labor costs, improves safety, and increases storage density. Custom dimensions are available for facilities with unique height or load requirements.
