Intelligent Steel Sheet Storage Solution – CE/ISO Certified Automated ASRS

Steel sheet storage rarely makes the maintenance meeting agenda — until a missing plate stalls the cutting line. Manual racks swallow floor space, forklift traffic slows every delivery, and operators lose minutes searching for the right gauge. Herochu’s Intelligent Steel Sheet Storage Solution takes that routine out of human hands. It is a CE/ISO certified automated ASRS built around vertical towers, PLC-controlled retrieval, and live inventory records, rated to carry up to 24 tons per set.

The storage problem most sheet metal shops share

Walk through a typical fabrication shop and the pattern repeats: pallets of plate stacked against walls, racks loaded without order, and one forklift driver who knows by memory where a specific sheet sits. When that memory fails, production waits. Horizontal racks spread plate across the floor instead of using the height of the building, so a plant with limited floor area often stores less than a single vertical tower could hold in the same space. Manual movement adds a second cost: every hand-off risks scratches, bending, or misplacement, and damaged plate becomes scrap money. These are exactly the costs an automated ASRS removes.

What the Herochu system does differently

The core of the system is a vertical tower divided into layers, each holding a steel tray. Plates rest flat on the trays, separated layer by layer, so any sheet can be retrieved without disturbing its neighbors. A high-strength elevator moves the material cart vertically, while a variable-frequency-driven conveyor exchanges trays at the inlet and outlet. Exchange and lift speeds of 5–15 m/min keep the cycle short enough to feed fast production lines. Repetitive positioning accuracy of ±2 mm means the tray lands where the next process expects it, every time. No manual handling, no forklift waiting in the storage aisle, no searching. One tower occupying roughly the footprint of two pallets can hold what previously required rows of racking spread across the shop.

PLC control with real-time monitoring

Every movement in the warehouse is supervised by a PLC. The control system monitors pallet positioning, measures steel plate weight, detects overheight plates, and verifies that storage slots are empty before each move. Sensor data is analyzed continuously, so faults are flagged the moment they appear instead of after the line stops. The same system compiles inventory statistics by dimensions, weight, and material specification — the operator always knows what is stored, where it is, and how much it weighs. All operation runs through a 15-inch touchscreen HMI. Default languages are Chinese and English, and region-specific language customization is available for export markets, so the interface can match the language spoken on the plant floor.

Certification and safety built in

The solution carries CE/ISO certification, covering product compliance and manufacturing quality. Sensors are rated IP67, so the system keeps functioning in the dusty environment typical of sheet metal processing. A safety guardrail runs across the front of the warehouse, and safety light curtains stop all movement the instant someone enters the working zone — protection against misoperation rather than a warning after the fact. The guard plates use a modern, simple design that suits both new facilities and retrofit installations, and keeps the equipment looking clean on the shop floor.

Steel that carries steel

Heavy plate needs an equally heavy-duty home. The frame is fabricated from large-section, high-strength thick-walled steel, giving the structure the rigidity to hold hundreds of tons across a long working life. Trays are made of Q345 steel, sandblasted, oxidized, and finished with electrostatic powder coating. In real-world tests, a single tray supports 5 tons. In the standard multi-layer configuration, one set stores up to 24 tons of steel sheet while occupying a fraction of the floor space that racking would demand.

Fits the way modern plants run

The system does not ask a plant to change its processes. It connects to existing production flows — feeding laser cutting machines, press brakes, or shearing lines — and inventory data can be shared with higher-level systems through standard industrial communication protocols, so ERP and WMS platforms can read stock levels without manual entry. Plants moving toward lights-out or semi-automated operation find the ASRS a natural first step, because it removes the most repetitive job on the floor: finding and moving plate by hand. The same data flow that supports automation also supports better purchasing decisions, because managers finally see what is actually in stock.

The economics of automated plate storage

The payback math is straightforward. A manual system costs floor space, forklift hours, and operator time every single day, whether or not anyone notices. The Herochu ASRS converts those recurring costs into one capital investment: the tower holds the same plate in a fraction of the area, retrieves it without a forklift, and records every transaction automatically. Plants that track their numbers typically find the system pays for itself through recovered floor space and reduced handling time — before counting the quieter savings, like fewer damaged sheets and fewer wrong-gauge mistakes reaching the machine. Those small losses are the ones that add up quietly over a year of two-shift operation.

Frequently asked questions

How many layers can the tower have? Standard configurations run eight layers, and the design supports up to 15. Layer count, tower count, and tray dimensions are customized to the plant’s plate sizes.

Can it handle thick, heavy plate? Yes. A single tray is tested to 5 tons, per-layer capacity reaches 5,000 kg, and one set stores up to 24 tons.

What power supply does it need? Input voltage can be 220 V or 380 V, at 50 Hz or 60 Hz, depending on the destination market.

Manual plate storage costs floor space, labor, and time. Herochu’s Intelligent Steel Sheet Storage Solution replaces that cost with an automated ASRS that tracks every sheet, moves it precisely, and records the transaction automatically — CE/ISO certified, and ready to connect to your production line.
