Custom Smart Material Racking System for long metal profiles, pipes and beams, ideal for laser cutting

“Custom” is one of the most overused words in industrial equipment marketing. In long-goods storage, however, customization is not a cosmetic option—it is the difference between a system that fits the factory and a system that forces the factory to fit it. A gantry ASRS for six-meter steel pipes and a gantry ASRS for eight-meter aluminum extrusions share a control philosophy but differ in structural engineering, tray geometry, load distribution, and safety envelope. Understanding what is actually customizable clarifies why these systems cannot be specified from a catalog page alone.

The mechanical core: gantry, tower, and tray

The Herochu Gantry-Type Pipe ASRS Warehouse System is built around four mechanical elements that function as a coordinated unit: the gantry loading and unloading system, the vertical rack towers, the material trays, and the floor-mounted guide rail system. The gantry spans the rack array and travels horizontally on linear guide rails, carrying a vertical lifting mechanism with an extraction tool that engages trays at any shelf level. Horizontal travel speeds range from 5 to 30 meters per minute; lifting speeds range from 5 to 15 meters per minute; positioning repeatability holds at ±2 millimeters—tight enough for automated tray engagement without operator correction. The drive system uses chain transmission paired with linear guide rails, chosen for reliability under heavy cyclical loads and in environments where dust, metal chips, and temperature variation are present.

The towers are cantilever-style rack structures arranged in rows along the guide rails, with each tower supporting multiple storage layers. The number of towers and layers scales with storage volume: a compact configuration might use six towers with five layers, while a high-capacity layout expands to ten towers with eight layers. Load capacity per level reaches 3,000 to 5,000 kilograms depending on the model, sufficient for bundled round pipes, square tubes, rectangular profiles, and structural sections.

What actually changes between installations

The variables that matter in a real deployment are the ones that connect the storage system to the factory’s physical and operational reality. Material length is the first: standard configurations accommodate 6,000 to 8,000 millimeters, but extended configurations are available for longer stock. Tray spacing and support intervals are engineered around the material’s deflection characteristics—long profiles stored horizontally tend to sag under their own weight, and the tray design must support material at calculated intervals along its length to preserve dimensional stability. Load capacity per level is specified against the actual bundle weights the factory handles, not against a nominal maximum. And the control layer—PLC touchscreen, WMS, WCS—is configured to the facility’s inventory logic and ERP/MES integration requirements.

Q: What does “ISO 9001 and CE certified” actually cover on a custom ASRS?
A: Certification applies to the manufacturing quality management system and the product’s conformity with applicable European health, safety, and environmental requirements. On a custom system, certification covers the engineered structure, the electrical and control components, and the safety devices—including anti-collision sensors and guarded access zones—rather than a fixed catalog design. Herochu’s systems are built to these certification standards as baseline specifications.

Q: How is safety handled when the system moves multi-ton bundles automatically?
A: Through a combination of physical guarding, sensor-based anti-collision devices, and control logic that prevents the gantry from entering an occupied zone. The operator interface is outside the rack aisle, and the automated cycle is interlocked so that manual access during motion is not possible. The safety architecture is designed into the custom configuration rather than added as an afterthought.

Q: Can a custom ASRS be expanded later without replacing the whole system?
A: In most cases, yes. The modular tower architecture allows additional tower sections and layers to be added within the original engineering envelope, and the gantry travel and control system can be extended to cover the expanded rack array. The practical constraint is the building’s height and floor capacity, not the storage system’s modularity.

The engineering reality behind “custom smart material racking” is therefore a set of interdependent decisions: gantry speed and repeatability, tower height and layer count, tray support geometry, load distribution, safety envelope, and control integration. A system that gets these right for a six-meter pipe inventory may be entirely wrong for an eight-meter extrusion inventory, even though both are “long goods.” Herochu’s approach is to engineer the gantry, tower, and tray as a single coordinated system around the customer’s material dimensions and throughput pattern, which is why the specification process begins with the material and the factory layout rather than with a standard model number.
