Pioneering global standards in automated storage and heavy-duty structural steel racking systems.
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.
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. 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.
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, ecommerce logistics hubs, and global retail enterprises to deliver reliable, efficient, and scalable storage infrastructure worldwide.
Advanced roll-forming lines, computerized machinery, and exhaustive testing instruments guaranteeing dimensional accuracy and high load capacity.
Selective pallet racking stands as the most widely deployed warehousing storage configuration globally, primarily due to its 100% selectivity. Unlike high-density systems (such as drive-in or push-back racking) that operate on Last-In, First-Out (LIFO) principles, selective configurations allow warehouse forklifts to access any pallet slot instantaneously without relocating neighboring loads. This structural characteristic eliminates product honeycombing and reduces overall cycle times in high-throughput fulfillment environments.
As supply chains pivot toward omni-channel distribution and just-in-time logistics, the ability to store highly diverse SKUs with instantaneous access is non-negotiable. Selective racking interfaces seamlessly with standard reach trucks, counterbalance forklifts, and Very Narrow Aisle (VNA) vehicles, ensuring low initial capital expenditure (CapEx) and maximum equipment interoperability.
In high-load warehouse structures, safety is paramount. Failure of a single racking component can lead to catastrophic progressive collapses, threatening worker safety and causing millions of dollars in inventory loss. A true CE certification denotes that the manufacturing and engineering practices of the selective racking system comply with European harmonized standards, specifically:
CE marked systems undergo rigorous finite element analysis (FEA) to assess dynamic impact resistance, structural deflection under maximum loading capacity, and seismic safety factors. For international importers, procurement of CE certified racking minimizes compliance risks, simplifies municipal building permits, and reduces commercial insurance premiums.
Leveraging domestic steel supply chains, optimized logistics hubs, and advanced roll-forming technology.
We source cold-rolled steel coils directly from state-owned enterprises, utilizing high-tensile Q235B and Q355B grades. This guarantees structural stability, superior load-bearing thresholds, and predictable elastic deformation curves under stress.
Our Shenzhen factory utilizes automatic multi-station continuous roll-forming mills, automated robotic CO2-shielded welding lines, and specialized electrostatic powder coating systems. This minimizes dimensional tolerance and guarantees consistent finish thickness (60-80 microns).
Backed by 35 QC professionals, our testing laboratory handles weld penetration analysis, cross-cut adhesion tests, digital bolt drawing verification, and coating thickness profiles. No batch exits the production floor without complete traceability certification.
The warehousing sector is undergoing a transformation driven by rapid e-commerce expansion and automated material handling. Standard static racking systems are no longer sufficient; they must integrate seamlessly with dynamic systems like AGVs (Automated Guided Vehicles) and AS/RS (Automated Storage and Retrieval Systems).
Modern selective racking profiles must accommodate the high-precision navigation sensors of laser-guided forklifts. This demands tighter structural tolerances and specialized floor anchoring systems. Tolerances outlined in EN 15620 Class 400 (VNA) require vertical deviation limits under 1mm per meter of height, ensuring that automated forks can insert and retrieve pallets without manual intervention or sensor collision.
For outdoor storage hubs, ports, and coastal zones, environmental corrosion presents a constant structural hazard. Selective racking systems designed for these areas utilize hot-dip galvanized (HDG) steel or specialized zinc-rich powder coatings. These treatments provide sacrificial galvanic protection, resisting salt spray corrosion and extending the racking system's operating lifespan to 20+ years.
Every industrial sector imposes specific demands on its warehouse racking architecture. Rather than relying on a generic design, we engineer systems tailored to specific vertical sectors:
Technical clarifications and procurement guidelines for global warehouse racking projects.
Complementary material handling pallets, AGV interfaces, and specialized high-density components.
