Sheet Metal Handling & Storage Rack Design for Fiber Laser Cutter

Sheet metal fabrication shops using fiber laser cutters face a daily challenge: raw sheets arrive in standard sizes (3000x1500mm, 4000x2000mm, up to 6000x2000mm), but storage space is always limited. Traditional sheet metal handling and storage rack design for fiber laser cutter applications often relies on A-frame racks or cantilever racks, which waste vertical space and require forklifts to maneuver between narrow aisles. Worse, pulling a sheet from the middle of a stack often scratches the sheet below. Herochu has reimagined sheet metal handling and storage rack design specifically for fiber laser cutters, introducing a drawer-type vertical rack that holds 3 to 6 tons per layer, with 100% extension for direct suction-cup retrieval.

The Core Problem in Sheet Metal Storage for Fiber Laser Cutters

Fiber laser cutters excel at cutting thin to medium-thickness sheets (1-20mm) with high speed and low maintenance. But the very speed that makes them productive creates a feeding bottleneck. If an operator spends two minutes retrieving a sheet from a traditional rack, the fiber laser cutter may sit idle for that same period. Over an eight-hour shift, idle time accumulates to lost production. Additionally, fiber laser cutters produce such smooth cut edges that operators often want to store finished parts immediately to prevent edge rust – but traditional storage racks don’t accommodate part sorting. Herochu’s sheet metal handling and storage rack design addresses both raw sheet feeding and finished part staging.

Herochu’s Drawer-Type Storage Rack – Engineered for Fiber Laser Workflows

The Herochu HC-B series rack is not a modified pallet rack. It is a purpose-built sheet metal handling and storage rack design for fiber laser cutter environments. Every component is cut on Herochu’s own fiber laser cutting machines, ensuring precision fit and structural integrity. The rack uses a bolted assembly – no welding required – so it can be disassembled and moved if your shop layout changes. Key models include:

• HC-B3015-63: 3000x1500mm sheet size, 6 layers (5 storage + 1 base), 3 tons per layer. External dimensions: 3505x2280x2000mm.

• HC-B4015-63: 4000x1500mm sheet size, 6 layers, 5 tons per layer. External dimensions: 4505x2280x2000mm.

• HC-B4020-65: 4000x2000mm sheet size, 6 layers, 5 tons per layer. External dimensions: 4505x2280x2500mm.

• HC-B6020-66: 6000x2000mm sheet size, 6 layers, 6 tons per layer. External dimensions: 6505x2280x2500mm.

The “drawer” mechanism is integrated pull-out type, meaning the entire shelf layer slides out on heavy-duty bearings. When fully extended, 100% of the sheet surface is exposed. An operator using a Herochu Servo Swing Arm Handling Manipulator can then apply suction cups directly to the sheet without reaching into a dark cavity. For shops without the manipulator, a forklift with extended forks can also access the fully extended drawer, though Herochu recommends the manipulator for scratch-free handling.

Vertical Space Utilization and Floor Area Savings

One of the most quoted statistics in Herochu’s sheet metal handling and storage rack design is 70-80% floor space reduction compared to flat floor storage. A workshop that stacks sheets flat on the floor using wooden dunnage needs the entire footprint of the sheet plus aisles for forklift access. The Herochu rack stacks sheets vertically, so a 4000x2000mm sheet occupies only its own footprint (approximately 8 square meters) regardless of whether it holds 6 sheets or 60 sheets. The rack’s overall width when doors are opened (i.e., when a drawer is extended) is factored into the external dimensions – Herochu provides both closed and open widths in the technical documentation so you can plan aisle space accurately.

Material and Construction Quality

Herochu constructs the rack frame from Q235B or Q355 high-strength structural steel. These grades offer yield strengths of 235 MPa and 355 MPa respectively, ensuring that even the 6-ton-per-layer HC-B6020-66 model does not experience permanent deflection under full load. The bolted connections use grade 8.8 fasteners, and each bolt hole is laser-cut with a precision that eliminates the need for shims or slotted holes. Users have reported installing Herochu racks in less than four hours with two people and a basic tool set.

Integration with Fiber Laser Cutter Loading

The ultimate test of any sheet metal handling and storage rack design for fiber laser cutter applications is how well it integrates with the loading process. Herochu’s design allows two loading methods:

1. Manual with Manipulator: The operator pulls out the required drawer. The Servo Swing Arm Manipulator picks the sheet and places it on the fiber laser cutter’s exchange table or cutting bed. The manipulator’s suction cups never touch the sheet below because the drawer is fully extended.

2. Semi-Automated with Conveyor: For shops with high-volume production, Herochu can install a roller conveyor at the drawer level. The sheet is pulled from the drawer onto the conveyor, then transferred to the fiber laser cutter’s automatic loading system.

The rack’s bottom layer ground clearance of 355mm is designed to accommodate the manipulator’s arm or a forklift pallet. Top floor height varies by model – the HC-B4020-65 reaches 2500mm, which fits under most standard workshop ceilings.

Safety and Load Testing

Every Herochu rack is load-tested before shipment. The test protocol applies 125% of rated load to each drawer for 24 hours, measuring frame deflection and bearing performance. The emergency stop and auto-braking mentioned in the manipulator specifications also apply to the rack when used with Herochu’s integrated system – if the manipulator stops, the rack’s drawer locking mechanism engages to prevent accidental sliding.

How to Specify Your Sheet Metal Handling and Storage Rack

When contacting Herochu for a sheet metal handling and storage rack design for your fiber laser cutter, provide:

• Sheet dimensions (length x width)

• Maximum sheet weight per piece

• Number of different material grades or thicknesses you need to store separately

• Desired number of layers (Herochu standard is 5+1, but custom configurations available)

• Your fiber laser cutting machine’s loading height and table size

Herochu’s technical team will respond with a CAD drawing, a bill of materials, and a quotation. On-site installation and debugging are available for international customers.

FAQ for Sheet Metal Rack Buyers

Q: Can the drawer-type rack hold aluminum sheets?
A: Yes. The rack’s steel construction and drawer bearings are compatible with aluminum, stainless steel, and mild steel. For soft aluminum (e.g., 1100 series), Herochu recommends adding a protective polyurethane mat on each drawer to prevent surface marking.

Q: Do I need a manipulator to use the rack?
A: No, you can use a forklift with extended forks. However, without the manipulator’s suction cup system, you risk scratching sheets when sliding them in and out. Herochu offers a combined package discount for rack + manipulator.

Q: What is the lead time for a custom-size rack?
A: Standard HC-B models ship within 15-20 days. Custom sizes (e.g., 5000x2000mm or 8 layers) require engineering review and typically ship within 30-35 days.
