High-capacity structural steel systems engineered for optimum density, safety, and seamless warehouse operations.
Established in 2015, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. is a leading manufacturer specializing in heavy-duty industrial racking and smart warehouse storage solutions. Operating from a modern production facility spanning 38,000 m², we leverage over 12 years of industry experience and 8 years of international trade expertise to serve global logistics and industrial sectors.
Our high-performance storage solutions generate an annual export revenue ranging between $18 million and $25 million, with core markets spanning North America, Western Europe, Southeast Asia, and the Middle East. Driven by strong R&D capabilities, our team of 28 skilled R&D engineers continuously innovates to meet evolving supply chain requirements, introducing over 120 new products and structural improvements annually.
Quality and precision are central to our operations. Our dynamic team of 35 dedicated QC professionals implements rigorous product inspection methods, including full raw material load-bearing analysis, high-precision weld seam testing, and comprehensive anti-corrosion powder-coating thickness checks. We offer extensive OEM/ODM custom options, including tailored load capacities, custom rack dimensions, color powder coatings, and fully integrated automated shuttle systems (AS/RS).
Backed by a strong network of over 800 supply chain partners, we primarily partner with large-scale 3PL providers, industrial distributors, e-commerce logistics hubs, and global retail enterprises to deliver reliable, efficient, and scalable storage infrastructure worldwide.
From raw material load deflection metrics to 3D printing design validation, every batch of cold-rolled steel undergoes rigid testing protocols to guarantee maximum safety thresholds in high-density installations.
Leveraging state-of-the-art automation and advanced fabrication tools at our 38,000 m² facility to maximize efficiency and build global supply chain resilience.

























Tailoring heavy-duty storage infrastructure to solve critical bottlenecks in industrial warehousing, high-throughput fulfillment, and cold storage logistics.
Maximizing volumetric efficiency and SKU accessibility is crucial for modern 3PL operations. Our multi-level selective pallet racking systems and radio shuttle racks permit rapid reconfigurability to adapt to dynamic client inventories while maintaining rigorous safety tolerances.
Operate with peak spatial efficiency in high-cost refrigerated and deep-freeze environments. Sunli's hot-dip galvanized drive-in racks and automated shuttle systems withstand temperatures down to -30°C without compromising structural integrity or brittle-fracture safety limits.
Integrating high-precision AS/RS structural racking with smart navigation AGV forklifts enables zero-error picker routes, minimizes overheads, and guarantees up to 99.9% order selection accuracy for global e-commerce and retail supply lines.
The paradigm of warehouse logistics is shifting from static storage to integrated cyber-physical systems. At Sunli, our technology roadmap prioritizes structural intelligence. Through structural IoT sensors and automated racking design, our team is developing real-time load deflection tracking that directly syncs with Warehouse Management Systems (WMS).
Future iterations of our heavy-lift structures leverage advanced high-strength steel grades to reduce dead weight while increasing load capacity limits. This structural refinement significantly reduces carbon emissions during transport and material fabrication, aligning with global green logistics mandates.
Moreover, the integration of AGV forklift pathways with adaptive multi-level shelving ensures that as automated fleets scale, the physical infrastructure remains dynamic, robust, and safe.
