Herochu sheet metal stack systems represent a fundamental advancement in how laser cutting stations manage raw material inventory. These are not simple shelving units; they are sophisticated material handling systems designed to integrate seamlessly with laser cutting workflows. The defining feature is the robust roll-out drawer mechanism that transforms sheet metal storage from a logistical challenge into a competitive advantage.

The Stacking Problem in Laser Cutting

Laser cutting stations require immediate access to a variety of sheet metal types, thicknesses, and sizes. Traditional stack systems—where sheets are piled on top of each other—create a cascade of operational problems. Retrieving a sheet from the middle of a stack requires lifting every sheet above it, risking damage to every surface touched. The physical demands of this process lead to operator fatigue and injury.

Furthermore, stack systems fail to protect sheet surfaces from scratching and deformation. When heavy sheets rest on each other, the weight distribution creates pressure points that can permanently mark or warp the material. These imperfections become costly defects when they appear in finished laser-cut parts.

Herochu sheet metal stack systems solve these problems by storing each sheet individually in dedicated drawers. Think of it as a massive, heavy-duty filing cabinet for metal plates. Each drawer holds a single sheet type, thickness, or bundle, providing complete separation between materials.

Vertical Stack Density

The Herochu sheet metal stack system leverages vertical space that traditional stacking leaves unused. Standard configurations include 5+1 layers—five storage layers plus a base layer—with the available height of each partition layer reaching up to 220 mm. This vertical density achieves 70% space reduction compared to conventional shelving.

For laser cutting stations, this space efficiency translates directly to productivity. More material can be stored within reach of the laser cutter, reducing travel time and material handling steps. Herochu systems can be configured with 8-12 customizable layers for even greater density, making them ideal for high-volume laser cutting operations that process multiple material types daily.

The high-density vertical roll-out sheet metal rack from Herochu achieves remarkable storage density through a multi-layer design that maximizes vertical space utilization. Each drawer stores sheets vertically while providing horizontal access, creating an efficient use of cubic volume.

Load Capacity and Structural Integrity

Herochu sheet metal stack systems are engineered for the extreme loads typical of laser cutting stations. Standard models handle 3 to 6 tons per layer, with customization available for heavier applications. The HC-B3015-63 supports 3000×1500 mm sheets at 3 tons per layer; the HC-B4020-65 accommodates 4000×2000 mm sheets at 5 tons; and the HC-B6020-66 handles 6000×2000 mm sheets at 6 tons.

The structural foundation of each system is Q235B high-strength carbon steel, chosen for its ideal balance of strength, plasticity, and welding properties. The dual-beam crossbar design distributes heavy loads evenly across the support structure, preventing deflection and fatigue. This engineering ensures the racking system maintains its integrity even under decades of dynamic industrial loading.

Each drawer in a Herochu stack system extends completely on heavy-duty steel bearings. The 100% extension capability is critical for laser cutting stations, where overhead cranes and vacuum lifters require unobstructed access to sheets. The lock-in and lock-out mechanisms for each drawer ensure safe operation during loading and retrieval.

Integration with Laser Cutting Automation

Herochu sheet metal stack systems are designed to complement laser cutting automation. The integrated pull-out drawer movement method allows single-person operation using lift equipment—vacuum lifters, magnets, or hoists. This integration creates a seamless material flow from storage to cutting bed.

When a sheet metal stack system is positioned adjacent to a laser cutting station, the workflow becomes remarkably efficient. Operators extend the drawer containing the required material, use a vacuum lifter to secure the sheet, and transport it directly to the laser cutting table. The entire process takes minutes rather than the 15-20 minutes typical of forklift-dependent systems.

Herochu systems can be integrated with full-automatic loading and unloading laser cutting machines, creating a synchronized production ecosystem. This automation capability allows laser cutting stations to achieve lights-out operation—running production through multiple shifts without manual material handling.

Protection of Material Quality

Sheet metal represents a significant capital investment for any laser cutting operation. Protecting this investment requires storage that prevents damage during handling and storage. Herochu sheet metal stack systems excel at material protection through individual drawer storage and full-surface support.

Each sheet rests on a flat drawer surface, supported across its entire area. This eliminates the pressure points and concentrated loads that cause deformation in stacked systems. The smooth glide of the drawer mechanism prevents the jerking and scraping that damages sheet edges and surfaces during retrieval.

The organized nature of the stack system also reduces inventory damage from mishandling. Operators can see exactly what material is available without disturbing other sheets. This visibility reduces the “digging” that damages sheet surfaces and edges in traditional stack systems.

Customization for Laser Cutting Requirements

Herochu recognizes that laser cutting stations have unique requirements based on the materials they process and the parts they produce. The company offers extensive customization options across all key parameters. Plate size configurations range from 3000×1500 mm to 6000×2000 mm, with custom dimensions available. Load capacity scales from 3 tons per layer to higher capacities for thick-gauge materials.

The number of layers can be adjusted to match production volume and available ceiling height. Standard 5+1 configurations accommodate most laser cutting operations, but additional layers are available for high-volume applications. The available height of partition layers adjusts to accommodate different material thicknesses, from thin gauge sheets to heavy plate.

Quality Assurance and Industry Standards

Herochu sheet metal stack systems carry ISO9001 and EU CE certifications, confirming compliance with international quality and safety standards. The company’s technical patents and industry recognition provide additional assurance of product quality. Herochu has signed strategic cooperation agreements with well-known domestic enterprises, demonstrating the trust that industry leaders place in the company’s products.
