Engineered for extreme load-bearing, workspace optimization, and high-efficiency material handling.
Established in 2015, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. has developed into a premier global manufacturing powerhouse specializing in heavy-duty industrial racking, automated storage components, and ergonomic warehousing solutions. From our headquarters and manufacturing base in Shenzhen, we deliver end-to-end consulting, design, manufacturing, and deployment services for global supply chain leaders.
Operating from a state-of-the-art production facility spanning over 38,000 m², we merge more than 12 years of industry engineering experience with 8 years of dedicated international trade operations. We support the evolving demands of Third-Party Logistics (3PL), e-commerce execution centers, manufacturing operations, and global retail chains. Our high-performance storage solutions generate an annual export revenue between $18 million and $25 million, ensuring global compliance with local structural safety standards in North America, Western Europe, Southeast Asia, and the Middle East.
How structural engineering meets worker health, safety compliance, and high-velocity throughput.
In the modern era of logistics, warehousing is no longer merely about static storage. The explosion of global e-commerce, combined with a tightening labor market and rising operational expenses, has forced a dramatic pivot toward ergonomic and automated storage configurations. Modern warehousing principles dictate that systems must adapt to the human operator—reducing fatigue, preventing musculoskeletal disorders, and minimizing travel time.
Ergonomic racking integration involves structural designs that facilitate easier reach zones (the "golden zone" between waist and shoulder height), reduce repetitive bending, and seamlessly integrate with smart warehouse automation like Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs). By providing custom-adjustable beam spacing, high-visibility loading metrics, and safe picking elevations, our ergonomic rack solutions help global operators reduce work-related injury claims while simultaneously boosting per-hour order picking rates by up to 25%.
Deploying racking solutions internationally demands strict compliance with regional structural code systems. As an exporter to North America, Western Europe, and the Asia-Pacific, Sunli designs and manufactures products complying with the highest domestic and international standards:
| Racking Attribute | Standard Configuration | Ergonomic Optimization | Target Applications |
|---|---|---|---|
| Selective Pallet Racking | Fixed heights, standard load capacity | Adjustable level steps, optimized picking heights | High-SKU diversity, manual-robotic hybrid picks |
| Push-Back & Gravity Systems | Standard incline gravity flow | Controlled deceleration, easy replenishment access | High-density storage, FIFO/LIFO rapid processing |
| AS/RS Smart Systems | Static high-bay structures | Full AGV interface, automated crane retrieval | Fulfillment centers, cold chain, dark warehouses |
| Medium-Duty Shelving | Multi-tiered shelving units | Anti-corrosion powder coating, step-less adjustment | Hardware, electronics, components retail hubs |
Inside our 38,000 m² factory: where structural steel is forged into high-load precision racking systems.
How our QC team of 35 specialists guarantees failure-proof storage systems for high-load installations.
Every structural component manufactured in our Shenzhen facility must pass rigorous metallurgical, load-bearing, and environmental resilience protocols. Structural failure in a warehouse containing thousands of tons of goods is catastrophic; our design team prevents this by integrating real-world destructive and non-destructive material evaluation processes before any batch is dispatched for international shipment.
Unlike factories that only measure structural calculations on paper, Sunli conducts routine destructive testing using the Digital Display Bolt Drawing Instrument and hydraulic frame testers. We load test structural weld joints up to 150% of their rated capacity, ensuring our systems withstand seismic anomalies and load misplacements.
Adapting heavy-duty racking systems to the unique structural and ergonomic needs of specialized sectors.
High throughput requires fast manual access and quick integration with pick-to-light systems. Our ergonomic racks optimize retrieval times and reduce worker strain through precise vertical slotting.
Cold storage costs are high per square meter. High-density structures, like AS/RS and push-back rack systems, operate flawlessly in extreme sub-zero temperatures (-25°C or lower) without steel embrittlement.
Automotive parts are heavy and unevenly balanced. We design customized heavy-duty racks with custom widths and ESD protection to ensure sensitive automotive and electronic components are stored safely.
How Sunli is engineering the future of automated and worker-safe warehousing infrastructure.
