Engineered high-capacity shelving systems and material handling equipment for global industrial hubs.
Unlike standard pallet racking systems that utilize vertical front columns to distribute weight, heavy-duty cantilever racks operate on a structural arm principle extending from a single vertical upright spine. This design provides unobstructed frontal access, which is critical for storing non-standard, linear, and high-density industrial materials such as steel tubes, structural timber, drywall sheets, extrusions, and heavy machinery assemblies.
The stability of a cantilever rack depends on structural mechanics. Base members must counteract the forward-tilting moment generated by loaded arms. The design uses structural H-beams or heavy roll-formed steel, engineered using finite element analysis (FEA) to ensure safety factors match or exceed standards like the ANSI/RMI MH16.3 specifications for industrial cantilever racking.
"By removing the front post limitation, a cantilever system changes structural storage layout efficiency, allowing crane-loading and specialized side-loader forklift access to maximize storage volume density."
Proper design requires evaluating arm deflection, load centers, and base-to-height stability ratios. Our heavy-duty racking uses high-strength structural grade steels such as Q235B and Q355B. This provides the load distribution capacity required to sustain dynamic impacts from material handling equipment.

Nanjing Dulis Warehouse Equipment Co., Ltd. (DuraRacks) is an integrated direct-export manufacturer specializing in heavy-duty industrial storage solutions.
Established in 2014, Nanjing Dulis Warehouse Equipment Co., Ltd. (operating globally under the brand DuraRacks) has developed over 12 years of industry experience and 9 years of direct export experience. Our main plant occupies a modern 38,000 square meter industrial facility in the logistics equipment manufacturing cluster of Nanjing, China.
We work with a network of over 1,200 qualified supply chain partners to deliver high-capacity industrial shelving systems, heavy-duty cantilever racks, and automated warehouse structures. Our primary markets cover North America, Western Europe, and Australia. We serve industrial clients including 3PL logistics hubs, large-scale e-commerce fulfillment centers, cold storage operators, and heavy industrial manufacturing plants.
From raw steel selection to powder-coating and quality control packing, our factory processes comply with ISO9001 and CE quality management parameters.
Our plant is equipped with automated machinery to maintain dimensional tolerances and surface coating thickness.
Our quality control processes align with ISO9001, CE, and FEM standards. The factory QA department uses dynamic testing facilities to verify load capacity and structural integrity under stress.
Our testing program includes:
To support global deployment, we configure systems to match regional requirements. We provide structural drawings that comply with RMI (USA), AS4084 (Australia), and FEM 10.2.09 (Europe) racking design standards.
Direct export minimizes intermediate markup. Working directly with our engineering team supports structural adjustments for specific wind, seismic, and floor loading conditions at your site.
Cantilever racks are utilized across various industries for specialized storage requirements.
Supports storing long items like steel pipes, copper tubes, and aluminum extrusions without bending. Side-loader forklifts can access inventory directly, reducing cycle times.
Protects lumber, plywood packs, gypsum board, and structural beams from damp flooring. Supports outdoor installation when paired with canopy roof structures.
Configured with continuous solid decking supports to store heavy steel tools and stamping dies, allowing overhead crane access.
The industrial warehousing market is shifting toward automated, high-density configurations. Cantilever designs are adapting to work with Automatic Guided Vehicles (AGVs) and crane retrieval systems. This requires high manufacturing accuracy, with tolerances controlled within ±1mm across the entire system height to prevent structural interference.
Additionally, environmental durability has become a priority. Warehouses in coastal or industrial chemical zones require structural protective coatings. DuraRacks offers hot-dip galvanized finishes and high-durability polyester powder coatings to protect steel surfaces in demanding environments.
