The automation of long goods storage has historically lagged behind other warehouse functions. The dimensions and weight of tubes, bars, and profiles present challenges that conventional automated storage and retrieval systems (ASRS) are not designed to address. The Automated Honeycomb Racking System for Tube & Bar Storage from Herochu bridges this gap, combining high-density honeycomb storage with rail-guided, gantry-served automation to deliver unprecedented efficiency in long goods warehousing.

The Convergence of Geometry and Automation

The automated honeycomb racking system represents the convergence of two powerful concepts: the space efficiency of hexagonal geometry and the operational efficiency of automated material handling. The honeycomb configuration provides the storage density necessary to maximize warehouse utilization, while the automated gantry system provides the speed and precision required for high-throughput operations.

Herochu’s automated system replaces random floor stacking with a rail-guided, gantry-served honeycomb rack that can cut floor-space demand by up to 60% and reduce handling times by 75%. This dramatic improvement in space utilization and operational efficiency makes the automated honeycomb racking system particularly valuable for facilities handling high volumes of tube and bar inventory.

Gantry-Based Retrieval and Storage

The automated honeycomb racking system utilizes a gantry-based retrieval mechanism that travels on a single linear guide rail, positioning pick-up or set-down operations with ±2 mm precision. This precision ensures accurate placement and retrieval of materials, minimizing the risk of damage during handling.

The gantry system achieves a maximum travel speed of 50 meters per minute, double that of competing systems which typically operate at 25 meters per minute. This speed advantage translates directly into higher throughput, allowing facilities to process more materials in less time. The system operates 24/7 without the need for forklift drivers or manual crane operators, eliminating handling errors such as misplaced inventory, dropped materials, or incorrect quantity picking.

High-Density Storage Configuration

The automated honeycomb racking system maintains the high-density storage characteristics of manual honeycomb racks while adding automation capabilities. Thousands of individual honeycomb storage locations provide far greater storage capacity than conventional racking systems. The hexagonal cells distribute load in six directions, creating a self-bracing structure that carries up to 7,000 pounds per slot while using 27% less steel than equivalent box-beam sections.

This combination of high density and structural efficiency makes the automated honeycomb racking system ideal for facilities where space is at a premium. The vertical utilization of warehouse volume reduces the footprint required for storage, freeing floor space for production or other value-added activities.

Accommodating Diverse Tube and Bar Inventories

The automated honeycomb racking system is designed to handle the full range of tube and bar inventory typically found in industrial warehouses and steel service centers. The system accommodates single or bundled stock from 6 meters to 12 meters in length. The honeycomb compartments can be configured to match specific material dimensions, ensuring that each tube or bar is stored in a dedicated position.

For facilities handling diverse inventories, the automated system provides continuous traceability of metal bar stock. Each storage location can be tracked within the inventory management system, providing real-time visibility into stock levels and locations. This traceability reduces the time spent searching for materials and improves inventory accuracy.

Operational Efficiency and Labor Savings

The automated honeycomb racking system delivers operational efficiency gains that extend beyond simple material handling. By automating the retrieval and storage process, the system eliminates the delays and errors associated with manual handling. The gantry system can retrieve materials in seconds rather than the minutes required for manual operations.

The labor savings from automation are substantial. Manual tube and bar handling typically requires multiple operators, often working in coordination to manage heavy loads. The automated system operates with minimal human intervention, freeing personnel for higher-value activities such as quality control, inventory management, or production supervision.

Integration with Existing Operations

The automated honeycomb racking system integrates with existing warehouse operations and infrastructure. The system supports overhead crane operations, allowing seamless transfer of materials between storage and production areas. The gantry system can be configured to deliver materials directly to cutting machines or CNC tools, creating an automated material flow that reduces handling steps and improves overall workflow efficiency.

For facilities with existing honeycomb racks, Herochu offers automation upgrades that add gantry-based retrieval capabilities to manual systems. This upgrade path protects previous investments while delivering the benefits of automation.

Long-Term Value and Scalability

The automated honeycomb racking system is designed for long-term value and scalability. The modular construction allows facilities to expand storage capacity by adding more honeycomb units without replacing the entire system. The gantry system can be extended to serve additional storage bays as capacity requirements grow.

The system’s durability is assured through ISO9001 and CE certified construction standards. Herochu’s engineering ensures that the automated honeycomb racking system maintains its performance through years of continuous operation, delivering a strong return on investment over its service life.
