When it comes to storing sheet metal, structural profiles, or long raw materials, conventional shelving often falls short. Enter the Industrial Cantilever Sheet Metal Rack with Extendable Arms for Heavy Storage—a purpose-built, high-capacity system that redefines how warehouses manage bulky, elongated inventory.
This advanced racking solution combines the strength of heavy-duty cantilever design with the intelligence of electric telescoping technology. Each arm can support between 2 to 6 tons, depending on the model, making it ideal for steel plates, aluminum sheets, copper coils, and composite panels. The HC-G9055D, for instance, offers a staggering 6-ton per-layer capacity and a total rack load of 42 tons, ensuring reliability even under extreme industrial demands.
What sets this system apart is its extendable arm functionality. Instead of requiring workers to reach deep into racks or use cranes for every retrieval, the arms glide forward at the touch of a button. This “grab-and-go” mechanism eliminates secondary handling, reduces product damage, and enhances worker safety. It’s particularly effective when integrated with overhead cranes or automated guided vehicles (AGVs), enabling fully mechanized workflows without manual intervention.

The rack’s modular design allows for flexible configuration. Choose from single or double-sided units, adjust vertical spacing between layers (600mm or 800mm standard), and select arm lengths from 550mm to 800mm—all customizable to match your material dimensions. Whether you’re storing 4-meter stainless steel sheets or 10-meter I-beams, the system accommodates varied lengths up to 12,000mm+.
Beyond performance, the rack excels in space efficiency. By removing the need for wide maneuvering aisles, it enables tighter row spacing and higher storage density. In facilities where floor space is at a premium, this can mean the difference between expanding your warehouse or optimizing within existing walls.
Durability is guaranteed through robust engineering: high-tensile steel frames, reinforced base columns, and anti-slip arm surfaces ensure stability even during dynamic loading. The PLC-controlled frequency conversion system provides precise speed regulation, soft start/stop motion, and overload protection—critical for protecting both equipment and personnel.

Backed by ISO9001 and CE certifications, and supported by Ji’nan Constant’s end-to-end service—from R&D to installation—this rack represents a long-term investment with a low total cost of ownership (TCO). Companies report doubled handling efficiency and 30% greater space utilization within weeks of deployment.
For any operation handling sheet metal or long goods, the Industrial Cantilever Sheet Metal Rack with Extendable Arms isn’t just practical—it’s transformative.
