Explore our newly engineered automated solutions and heavy-duty steel structures designed to maximize warehousing efficiency.
Established in 2015, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. has developed into a premier global enterprise specializing in heavy-duty industrial racking systems, custom transport racks, and automated warehouse logistics solutions. Operating from our advanced, state-of-the-art production base spanning over 38,000 m², we successfully bridge structural precision engineering with high-capacity warehouse efficiency.
Leveraging over 12 years of core industry design experience and 8 years of professional international trade expertise, our engineering department designs optimized layouts that maximize storage density while maintaining strict regulatory safety factors. Our annual export operations range between $18 million and $25 million, supporting key supply chain operations in North America, Western Europe, Southeast Asia, and the Middle East.
A comprehensive breakdown of our roll-forming machinery, automated production tools, and precision tooling lines.
Why global enterprises rely on Chinese production clusters for precision-engineered heavy storage infrastructure.
We source certified structural steels (specifically Q235B and Q355B grades) from China's leading mills. These materials feature high yield strengths and uniform grain structures essential for heavy structural load-bearing reliability under mechanical stress.
Based in Shenzhen, we tap into a dense industrial cluster of advanced robotics, smart controls, and automated engineering suppliers. This ecosystem drives cost-effective hardware integration, including laser sensors, AGV control units, and automated shuttles.
Our facility's close proximity to major deep-water ports (Shenzhen and Guangzhou) guarantees efficient marine container transport. We utilize customized steel packing methods to optimize loading density and minimize international shipping freight costs.
Ensuring our engineered racking products comply with international structural safety and loading performance guidelines.
For global heavy-duty racking suppliers, safety is non-negotiable. Shenzhen Sunli structures undergo precise engineering calculations referencing ANSI/RMI MH16.1 (Specification for the Design, Testing and Utilization of Industrial Steel Storage Racks) and the European EN 15512 steel structural standards.
Our structural engineering team leverages finite element analysis (FEA) to verify stress, buckling states, and deflection margins under static and dynamic loads. This is critical for sites situated in seismic hazard zones where local structural codes require base plate anchoring modifications and engineered frame configurations.
From initial design inputs to on-site assembly, here is how we customize rack configurations for heavy logistics operations.
Our engineers assess your facility's layout, material handling gear (forklifts, AGVs), pallet weights (ranging from 500KG to 2500KG per level), temperature zones, and ceiling heights to determine optimal rack footprints.
Utilizing high-end CAD tools and structural analysis software, we model critical joints, load beams, and upright posts under worst-case loading configurations to verify design safety factors and prevent stress points.
Approved designs proceed to production. Heavy-duty cold-rolling mills form profiles from Q235B steel coils, while automated robotic welders apply clean welds to connector tabs and base plates, avoiding thermal distortions.
Finished steel components undergo testing for coating thickness, cross-cut adhesion, and tensile draw strength. The parts then receive a high-durability electrostatic powder coating to prevent corrosion in humid or cold environments.
Discover how our high-capacity storage racks and smart AGV equipment solve material handling bottlenecks across global markets.
Fulfillment operations require high density and rapid picking cycles. Our integrated mezzanine flooring platforms and multi-layer shelving units optimize vertical cubic space, creating pathways for automated sorting and cart logistics.
Automotive and industrial production lines handle dense, heavy components. Sunli's heavy-duty selective pallet racks and customized transport frames sustain extreme load profiles while ensuring fast forklift accessibility.
Cold-chain space is expensive. We build high-density Automated Radio Shuttle Rack systems coated with special low-temperature powder treatments, maintaining structural integrity down to -30°C.
