A modern industrial facility rarely stores a single material. A typical service center may hold carbon steel seamless pipe for pressure applications, welded steel tubing for structural fabrications, and aluminum extrusions for lightweight framework—all under the same roof. Managing these materials with conventional floor stacking or generic cantilever racking creates a predictable set of problems: bundles get mixed, grades get misidentified, and aluminum surfaces get scratched or dented by steel-handling equipment. The industrial pipe storage warehouse from Herochu is engineered to solve exactly these problems by integrating storage, handling, and inventory control into a single automated system.

Rather than treating the warehouse as a building that happens to contain racks, Herochu approaches it as a coordinated storage and retrieval operation. The gantry manipulator, the storage tower bank, the PLC controller, and the inventory database are designed to work together from the outset. This integration is what distinguishes a storage warehouse from a collection of racks.

Universal Material Versatility: Steel, Aluminum, and Beyond

Steel and aluminum have different handling requirements. Steel bundles are heavy, resistant to surface damage, and often stored in large-diameter formats. Aluminum tubes and profiles are lighter per unit length but demand scratch-free handling, because cosmetic surface defects can downgrade the material or trigger customer rejection. The Herochu storage system addresses both through universal material versatility: modular bins engineered to securely store pipes, beams, and long profiles, compatible with loose or bundled materials up to 12 meters in length.

The bin cradles are lined with replaceable wear strips—typically high-density polyethylene or hardened steel depending on the application—that prevent metal-on-metal contact between the stored bundle and the bin structure. For aluminum storage, the fork engagement surfaces use padded contact pads that distribute clamping force over a wide area, eliminating the point-loading that marks soft alloy surfaces. The same gantry fork retrieves a 5,000 kg steel bundle in one cycle and a lighter aluminum profile bundle in the next, without reconfiguration.

This versatility extends to material format. The bins accommodate:

• Long bundles: full 6-meter, 8-meter, or longer seamless and welded pipe
• Short bars and remnant stock: offcuts and partial-length material that accumulate in fabrication shops
• Loose material: individual bars or tubes not secured in bundle form

Storing all three formats in a single system eliminates the need for a separate short-bar storage area and a separate remnant rack, which are typically the most disorganized zones in a conventional warehouse.

Smart Scalability for Evolving Logistics Demands

A warehouse built for today’s throughput may be undersized within three years. The Herochu storage system is designed for smart scalability: customizable layout and modular shelf architecture allow rapid expansion to meet evolving logistics demands. Because the gantry rail is segmented and the storage towers are self-standing modules, a facility can add towers or additional storage levels without replacing the existing infrastructure.

The gantry manipulator itself is specified for the maximum anticipated travel length. If the initial installation includes six towers along a 20-meter rail, the system can later extend to eight or ten towers along a longer rail, provided the rail extension and additional towers are installed to the same flatness and alignment tolerances. The PLC software accommodates the expanded bin map, and the touchscreen interface updates to display the additional storage locations. This is modular expansion without operational disruption.

The configurable models illustrate the scalability path:

• HC-XG6053-6: 6,000 mm length, five levels, 3,000 kg/level, six towers
• HC-XG8055-8: 8,000 mm length, five levels, 5,000 kg/level, eight towers
• HC-XG8085-10: 8,000 mm length, eight levels, 5,000 kg/level, ten towers

A facility that begins with the HC-XG6053-6 for lighter gauge product can scale to the HC-XG8085-10 configuration as volume and material size increase, without retraining staff or replacing the control system.

Fail-Safe Protection for Equipment and Personnel

Automated storage systems handle heavy loads at controlled speeds, which means safety cannot rely on operator vigilance alone. Herochu integrates intelligent laser sensors and real-time load monitoring throughout the gantry system to ensure maximum safety for both equipment and personnel.

The safety architecture operates on multiple layers. Laser scanners mounted on the gantry carriage define a detection field around the manipulator’s travel path. If a person or object enters the field, the gantry decelerates and halts according to a programmed response curve. At the bin engagement point, load cells on the fork assembly verify that the engaged bundle weight matches the expected value before the lift sequence proceeds. An unexpected weight deviation triggers an alarm and halts the cycle, preventing the system from lifting a partial load or an incorrectly identified bundle.

During vertical lifting, the load monitoring system tracks the lifting force in real time. If the force exceeds the expected range for the commanded bundle—indicating a jammed load, an entangled bundle, or a structural obstruction—the gantry stops and signals an operator alert. These protections are active during every storage and retrieval cycle, not just during commissioning.

Electrostatic Powder Coating for Multi-Metal Environments

In a warehouse that stores both steel and aluminum, galvanic corrosion is a real concern. When dissimilar metals contact each other in the presence of moisture, the less noble metal (aluminum) corrodes preferentially. The storage structure itself is steel, which means the bin surfaces must be electrically isolated from the aluminum product. Herochu applies an electrostatic powder coating to all structural surfaces, which provides both the corrosion resistance and the dielectric separation needed.

The powder coating process begins with surface preparation to Sa 2.5 standard, followed by electrostatic spray application of a thermoset powder that is oven-cured to a hard, continuous film. The cured coating is non-conductive, which means aluminum bundles resting on coated bin surfaces are galvanically isolated from the steel structure. The coating also resists the cutting fluids, lubricants, and atmospheric humidity present in industrial environments, protecting the structure from rust and extending the maintenance interval significantly.

For outdoor or semi-open storage yards, the coating system can be upgraded to a duplex specification—powder over hot-dip galvanizing—for maximum service life in corrosive atmospheres.

Double-Sided Design for Mixed-Material Banks

The double-sided design of the Herochu storage tower bank enables a practical mixed-material layout. One face of the tower bank can be dedicated to steel pipe storage, while the opposite face stores aluminum tubes and profiles. The gantry manipulator serves both faces from the shared rail, retrieving a steel bundle for one production order and then an aluminum bundle for the next, all under the same control system and inventory database.

This configuration is more than a space optimization. It allows the warehouse to segregate materials by handling requirements—steel on one side, aluminum on the other—while maintaining a single retrieval system and a single inventory record. Operators do not need to move between two separate storage zones; the gantry delivers the requested material to one outbound station regardless of which face it was stored on.

PLC Control and Digital Inventory Across Material Types

The PLC touchscreen control maintains a real-time digital inventory that tracks each stored bundle by material grade, dimensions, weight, and storage location. For a warehouse handling multiple metal types, this level of tracking is essential. The system can report at any moment how many bundles of a specific aluminum alloy are in stock, where each bundle is located, and when it was stored. The same query applies to carbon steel, alloy steel, or any other material in the system.

When integrated with the warehouse management system or ERP, this transaction-level tracking ensures that the material issued to production matches the material specified in the work order. For operations supplying certified material—where traceability is a contractual requirement—the digital inventory record provides an auditable history from inbound receipt to outbound issue.

The Herochu industrial pipe storage warehouse is built around this principle: the value is not in the rack, but in the coordinated system that stores, tracks, and protects the material. For steel and aluminum tube distributors, that coordination is the difference between a warehouse that functions and one that merely contains inventory.
