Explore our heavy-duty steel structures and high-density racking configurations engineered to optimize space and efficiency.
Established in 2015, Ningbo Xinmiao Storage Equipment Co., Ltd. is a leading manufacturer specializing in heavy-duty pallet racking, industrial shelving, and intelligent warehouse storage systems. Spanning a modern manufacturing facility of over 35,000 square meters, we have dedicated over 14 years to the industry, providing robust and reliable storage solutions to global enterprise clients. With 8 years of direct export experience, our products are trusted in key markets across North America, Europe, Southeast Asia, and the Middle East, generating an annual export revenue exceeding $18 million.
Driven by a highly skilled team of 18 R&D engineers, we offer strong OEM/ODM and full custom-tailoring capabilities—from structural engineering and custom dimensions to specialized powder-coating finishes. Continuously advancing warehouse technology, we launched 45 new innovative products last year to support our global partners in optimizing space and efficiency.
In modern industrial logistics, standard selective pallet racking fails to address the spatial problems presented by long, irregular, or high-volume linear materials. Structural profiles, pipelines, timber products, sheet metal, and industrial extrusion products represent severe storage density challenges. Traditional methods often require stack storage or floor grouping, which increases the footprint requirement while limiting mechanical accessibility and introducing severe structural hazards.
Engineered OEM/ODM cantilever storage structures eliminate upright obstructions to deliver continuous horizontal storage. By removing the front-most vertical structural pillar, cantilever racks allow uninterrupted placement of structural material. Under the current trajectory of international supply chain systems, third-party logistics providers (3PL) and manufacturing entities are transitioning from conventional layouts to specialized cantilever layouts. This change yields an average storage volume enhancement of 35% to 50% relative to floor-based systems, while significantly accelerating picking and loading cycles for forklift operators.
Structural Integrity Mandate: Operating with load tolerances up to 5,000 kg per arm requires meticulous steel composition. Ningbo Xinmiao designs systems with strict deflection coefficients compliant with the global L/200 standard, preventing mechanical deformation under sustained load conditions.
To design an optimized cantilever racking system, engineers must calculate the exact physical dimensions and bending moments of the materials being stored. Upright columns act as the main structural support, bearing vertical loads and countering the moment forces created by extended cantilever arms. Structural bases distribute loads evenly across concrete floors to maintain structural stability.
OEM customization allows clients to tailor structural columns (heights up to 12 meters), cantilever arms (lengths from 500 mm to 2,000 mm), and horizontal base dimensions to their precise storage layout. These configurations can be single-sided, for perimeter installation, or double-sided, to maximize aisle efficiency. Additional structural elements, including end-stop pins, pipe retaining collars, and integrated steel guide rails, protect both inventory and storage equipment from damage during forklift operations.
Our 35,000-square-meter facility features automated manufacturing equipment, enabling us to trace materials and verify load tolerances throughout production.
Quality and structural integrity are at the core of our manufacturing philosophy. Backed by a strong network of over 800 supply chain partners, our operation is supported by a dedicated team of 25 Quality Control (QC) specialists. We implement comprehensive non-destructive testing (NDT), load-bearing stress evaluations, and automated ultrasonic weld inspections to ensure that every rack meets stringent international safety standards.
Our raw steel profiles are sourced exclusively from certified metallurgical mills, selecting only high-grade Q235 and Q355B structural carbon steel. During the rolling stage, computer-controlled roll-forming systems shape the structural channel columns, keeping thickness tolerances within 0.05 mm. Standardized vertical punching systems create precise connection spacing, allowing users to adjust cantilever arm heights in increments of 75 mm or 100 mm to optimize space utilization.
Industrial storage systems operate under strict regulatory and safety codes that vary by region. In North America, the Rack Manufacturers Institute (RMI) governs these structures under the ANSI/RMI MH16.1 standard, which sets criteria for mechanical loads, seismic design, and anchor configurations. Systems installed in European markets must comply with EN 15512 (Steel Static Storage Systems - Adjustable Pallet Racking Systems - Principles for Structural Design) and EN 15635 (Application and Maintenance of Storage Equipment).
As an export-oriented manufacturer, we primarily serve third-party logistics (3PL) providers, global distributors, and large-scale industrial enterprise clients. Ningbo Xinmiao partners with certified mechanical engineering firms to perform region-specific structural calculations. Our designs factor in local seismic hazards, base plate thickness requirements, and high-strength anchoring systems, helping customers secure fast regulatory approvals and passing local safety inspections.
| Regional Standard | Primary Authority | Seismic Requirement Focus | Deflection Limits Allowed |
|---|---|---|---|
| ANSI/RMI MH16.1 | North America (RMI) | Seismic Force Factors & Column Base Plate Dimensions | L/240 of Arm Length |
| EN 15512 / EN 15635 | Europe (CEN) | Global Buckling Analysis & Structural Safe-Load Tolerances | L/200 of Arm Length |
| AS 4084 | Australia | Base Plate Shear Anchoring & Frame Upright Deflection Limits | L/250 of Arm Length |
The warehouse equipment sector is shifting toward automation, driving changes in standard heavy-duty structural steel designs. As automated guided vehicles (AGVs) and AS/RS (Automated Storage and Retrieval Systems) become more common, racking systems require tighter mechanical tolerances. Conventional manual setups are giving way to automated cantilever systems, which use precise laser coordinates to place loads with minimal error margins.
Ningbo Xinmiao is investing in this transition by manufacturing high-precision roll-formed shapes designed for automated crane integration. Our R&D team is developing smart cantilever systems featuring integrated strain-gauge sensors that monitor load conditions and arm deflection in real time. These IoT-enabled safety systems alert operators to load anomalies or structural shifting, preventing workplace accidents and extending the operating life of the warehouse infrastructure.
