Metal fabrication facilities handle thousands of linear meters of raw stock every month—steel pipes in various diameters and wall thicknesses, rebar bundles for concrete reinforcement, structural profiles for building construction, and tubing for automotive and industrial applications. When these materials sprawl across cantilever racks or floor-level pallets, they consume disproportionate warehouse square footage and create daily bottlenecks in material retrieval.

The challenges are particularly acute for heavy loads. A single bundle of large-diameter pipe can weigh several tons. A rack of rebar sections may exceed 5,000 kg per level. Traditional storage methods require heavy-duty forklifts or overhead cranes for every movement, introducing safety risks and limiting retrieval speed. Inventory accuracy suffers because counting heavy materials is physically demanding and time-consuming. Workers spend hours navigating cluttered aisles to locate a single length of pipe; valuable vertical space goes unused; and the risk of material damage or workplace injury remains persistently high.

Herochu has engineered the Automated Pipe & Rebar Racking System specifically to address these challenges. The system replaces horizontal sprawl with vertical density, condensing chaotic floor storage into a digitally managed multi-level rack structure that rises from five to thirteen levels depending on ceiling clearance, with each shelf tier engineered for loads reaching 3,000 kg to 5,000 kg per level.

High-Density Vertical Storage Architecture

The defining feature of the Herochu Automated Pipe & Rebar Racking System is its vertical stacking architecture. Rather than allocating aisle after aisle to ground-level racks, the system uses multiple independently moving storage layers arranged in tower configurations. Each tower accommodates pipe lengths from 6,000 mm to 8,000 mm across five to eight customizable layers, with per-level load ratings reaching 5,000 kg.

The rack structure is engineered from heavy-duty steel with columns, bases, and arms manufactured from premium H-shaped steel or welded C-shaped steel depending on load requirements. The system includes open-bottom drawers that allow swarf and coolant to drop through during cutting operations, with perimeter retention pins and closed-side options to protect round stock from rolling off during storage and retrieval.

The floor-mounted rail system with shared picking aisle optimizes space utilization while maintaining accessibility. The shelf layout is tailored to on-site material requirements, with bin configurations that accommodate both long and short materials as well as loose items. This flexibility ensures that the system adapts to the specific material mix of each facility rather than forcing operations into a rigid storage geometry.

Precision Automation and Real-Time Control

The gantry-based retrieval system operates with ±2 mm repeatability, ensuring precise positioning for every storage and retrieval operation. Horizontal travel speed ranges from 5 to 30 meters per minute, with lifting speed adjustable from 5 to 15 meters per minute. The system is controlled through a PLC touchscreen interface that provides real-time inventory display and digital inventory management.

The warehouse control system maintains a three-dimensional cell map in which every cantilever arm position is mapped to a unique three-coordinate address: rack row number, bay number within the row, and arm level number within the bay. The system database stores this address alongside the material SKU, heat number or batch code, quantity in the cell, length, and put-away timestamp. Every movement is a PLC-logged transaction, ensuring that inventory records remain accurate and current.

Direct Operational Benefits

The Herochu Automated Pipe & Rebar Racking System delivers immediate and measurable operational improvements. Material retrieval time drops from 15–20 minutes of manual searching to approximately 90 seconds of automated delivery. Mispicks—errors in selecting the wrong diameter, grade, or length—are reduced by over 92%. Floor space utilization improves by more than 80% compared to conventional storage layouts.

Safety improvements are equally significant. The system eliminates hazardous manual climbing, heavy overhead crane operations for routine stock picking, and ladder usage. For facilities operating multi-shift schedules, the system enables “lights-out” overnight material feeding and continuous automated cutting cycles. This capability translates directly to increased machine utilization and higher throughput without additional labor costs.

Herochu manufactures this Automated Pipe & Rebar Racking System in its ISO 9001-certified facility with CE compliance and mandatory pre-shipment structural load testing. The company offers custom design engineering, zero minimum order quantity, and worldwide on-site installation, debugging, and operational training. For facilities seeking to transform heavy long goods storage from a cost center to a competitive advantage, the Herochu Automated Pipe & Rebar Racking System delivers the density, precision, and intelligence required to meet modern production demands.
