Explore our certified range of industrial steel racks, automated shuttle units, and custom storage solutions designed for structural integrity and high-density capacity.
A trusted global leader in structural engineering, automated warehousing integration, and custom racking systems manufacture.
Established in 2015, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. has developed into a premier 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. Our quality standards comply strictly with ISO9001 and CE regulations.
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 structural design and raw material verification to advanced robotic welding and electrostatic powder coating lines.
Ensuring absolute compliance with strict European and American safety standard load factors through advanced testing instruments.
An in-depth analysis of supply chain vertical integration, advanced material grades, and high-density warehouse automation trends.
The global dominance of Chinese pallet storage manufacturers is primarily driven by immediate proximity to state-run steel manufacturing clusters. Shenzhen Sunli Intelligent Logistics Equipment utilizes certified Q235B and Q355B structural steel, processed via high-speed computerized roll-forming systems. This ensures optimized yield strength, elastic deformation thresholds, and predictable performance under high-gravity loads.
Compared to localized regional manufacturing hubs, the integration of structural cold-rolling mills directly adjacent to raw material coils minimizes logistics latency. The results are significant: robust steel structural profiles (such as 90mm x 70mm and 120mm x 95mm upright columns) with precision pitch punching (50mm or 75m) that offer consistent load tolerance profiles of up to 4000kg per level. By controlling the supply line from coil to chemical powder formulation, Sunli delivers high structural durability while maintaining extreme cost efficiency.
Modern global logistics is undergoing a rapid transition from simple static storage layouts to high-throughput, automated solutions. Warehousing costs and urban land scarcities demand vertical expansion. The integration of Automated Storage and Retrieval Systems (AS/RS), autonomous laser-guided forklifts (AGVs), and Radio Shuttle Racking systems maximizes vertical space utilization (up to 40 meters in high-bay structures) while reducing operational cycle times.
Our autonomous laser-guided forklift models (such as the SL-AGV-1000BY-01) operate for 6 to 8 hours continuously, utilizing obstacle-avoidance sensors to transport 800KG payloads safely. These smart vehicles operate harmoniously with deep-lane radio shuttle racks, replacing traditional reach trucks. This dynamic combination eliminates unnecessary aisle space, effectively doubling storage densities while significantly reducing picking errors.
Multinational procurement managers increasingly demand strict structural verification. Custom storage configurations must satisfy specific geographical safety guidelines, such as the Rack Manufacturers Institute (RMI) standards in North America and FEM 10.2.02 regulations in the European Union. Furthermore, the rising frequency of global seismic events requires tailored structural designs. This includes heavy-duty baseplates, additional frame bracing, and custom anchor pull-out test values verified by digital drawing instruments.
At Shenzhen Sunli, we satisfy these rigorous criteria by using high-strength steel uprights and heavy-duty box/stepped beams. These structural configurations are analyzed with Finite Element Analysis (FEA) software before manufacture. The powder-coated layers undergo cross-cut adhesion and impact testing to prevent oxidation in harsh environments, such as sub-zero cold storage facilities and high-humidity chemical storage centers.
Custom OEM configurations tailored to specific operational challenges, environmental conditions, and material flow rates.
Utilizing low-temperature resistant Q355D structural steel with high-tensile properties. Features specialized powder coatings that prevent micro-cracking and moisture oxidation at temperatures as low as -30°C. Optimized for maximum density using dynamic shuttle racking systems.
High-bay multi-tier mezzanine floor integrations combined with medium-duty shelving and dynamic gravity flow configurations. Designed to facilitate ultra-fast picking rates and rapid inventory turns, offering direct compatibility with automated AGV systems.
