While sheet metal storage has received significant attention in automated factory literature, the handling of longer, heavier, and more geometrically diverse materials—steel plates, structural profiles, pipes, and beams—remains an underserved challenge. Many warehouses continue to rely on ground-level ground racks or cantilever systems that consume vast floor areas and require manual searching and retrieval. Herochu has addressed this gap with its Intelligent Automatic Plate Storage Warehouse for Steel Plates Profiles 3 ton load capacity per level, a vertically oriented automated storage and retrieval system (AS/RS) purpose-built for the unique demands of long-span materials.

This system is distinct from the plate-only towers described previously. It is engineered to accommodate both flat steel plates and a wide variety of profiles including rebar, H-beams, I-beams, C-channels, and square or rectangular tubes. The maximum material length is 6000 mm, which covers the majority of structural steel sizes used in construction, bridge fabrication, heavy equipment manufacturing, and shipbuilding. Each level within the tower supports a 3‑ton load capacity—a deliberately chosen rating that balances structural integrity with practical utility. For most profile sections, 3 tons represents between 10 and 30 individual pieces, depending on wall thickness and alloy.

The Herochu intelligent automatic plate storage warehouse employs a double-tower configuration for profile storage, similar in concept to the sheet metal double-tower series but with critical adaptations. First, the plate supports are replaced with adjustable profile cradles that can be reconfigured without tools. These cradles feature V-rollers or flat polyurethane pads, selectable at the time of order. Second, the entry station is lengthened to 6500 mm to accommodate the full material length plus over-travel. Third, the vertical lifting mechanism is reinforced with dual chain drives and a guided carriage that prevents swinging—a common failure mode in profile storage systems where long, slender materials can oscillate during lifting.

The double‑tower tube and bar storage series offers a 3 ton load capacity per level and accommodates materials up to 6000 mm in length. It is useful for storing pipes, rebar, H/I/C beams, and other long‑span materials. This versatility makes the Herochu system a single solution for what would otherwise require three or four specialized storage products. A fabrication shop that works with both steel plates for skid bases and structural tubes for frames can store both material types in the same system, with the software automatically segregating them by level or by tower.

The operational logic of the intelligent automatic plate storage warehouse mirrors that of the sheet metal series but adds a few specialized features. Automatic weight detection is implemented using four load cells under the entry station, which measure the total mass of the incoming bundle. Because profiles are often stored in nested or bundled configurations, the system also performs a length scan using through-beam lasers to verify that no material extends beyond the 6000 mm limit. Any over-length material is rejected immediately, preventing damage to the storage structure.

Automatic storage and automatic delivery are handled through the same PLC touch screen control interface used across the Herochu product line. Operators select a material family (e.g., “H-beam 200×200”), input dimensions and quantity, and the system recommends a storage level based on current inventory and upcoming production orders. The recommended location accounts for material weight distribution—heavier items are stored on lower levels to maintain the tower’s center of gravity, while frequently retrieved items are placed near the entry station for faster access.

Safety and efficiency are interlinked in this system. The Safe and efficient, heavy load bearing design philosophy is evident in the choice of linear guide rails and chain drives, which provide positive engagement even under the eccentric loads typical of profile storage. When a bundle of pipes is stored, its weight is not evenly distributed along the length; the chain drive and guide rail system accommodate this by distributing the load across multiple bearings. The two loading modes: forklift and overhead crane are also supported, but with profile-specific attachments. Forklift loading is recommended for bundled materials, while overhead crane loading is preferred for individual heavy beams exceeding 1.5 tons.

A unique safety feature in the profile storage series is the sway damper—a mechanical brake that engages whenever the vertical lift carriage is stationary. This prevents the natural pendulum motion that occurs when a long steel beam comes to rest, keeping the stored profiles aligned and preventing them from contacting the tower walls. The sway damper is controlled by the same PLC that manages lifting and lowering, ensuring coordinated operation.

The number of floors in the profile storage tower is typically 8 to 12, with each level spaced at 350 mm to 500 mm increments depending on the maximum profile height. Standard tower widths are 4015, 6015, and 6025 mm, matching the sheet metal series to simplify factory layouts when both systems are installed side by side. Vertical lifting speed is 9 m/min, and inlet/outlet speed is 12 m/min, consistent with the rest of the Herochu product family.

For workshops operating 24/7, the Herochu intelligent automatic plate storage warehouse includes expandable ERP/MES connectivity that supports continuous operation without manual intervention. The system can be programmed to automatically replenish the production line’s buffer stock based on real-time consumption data. For example, if a downstream saw or laser tube cutter reports that it has fewer than five beams remaining, the storage system will retrieve and deliver the next bundle without any operator action. This level of automation is essential for dark factory or lights-out manufacturing environments.

Customizable shelf heights are available to accommodate unusual profile dimensions, such as tall I-beams or wide flange sections. The modular architecture of the system enables standalone material storage—useful for warehouses that are not yet ready to automate their cutting processes—or seamless integration with third-party laser cutting machines through standard I/O interfaces. Herochu provides a compatibility list for major laser brands, including Trumpf, Amada, Bystronic, and Mazak, as well as plasma and waterjet cutting systems.

In summary, the Herochu intelligent automatic plate storage warehouse for steel plates and profiles is a purpose-built solution for the structural steel and heavy fabrication industries. Its 3-ton per level capacity, 6000 mm length accommodation, and double-tower design provide a storage density that is impossible to achieve with floor racks or cantilever systems. By automating weight detection, storage assignment, and retrieval, it eliminates the physical strain and time waste of manual material handling. For any facility that processes plates, beams, pipes, or channels in volume, this system represents a quantifiable step toward full production automation.
