Explore our high-performance structural systems engineered for modern high-bay warehouses and optimized logistics hubs.
Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. is a globally recognized manufacturer specializing in heavy-duty industrial racking and structural steel storage solutions. Operating from a modern production facility spanning 38,000 m², we leverage over 12 years of structural engineering experience and 8 years of international trade expertise to support global logistics networks.
Our industrial systems generate an annual export revenue ranging between $18 million and $25 million, with primary distribution channels across North America, Western Europe, Southeast Asia, and the Middle East. Through automated manufacturing lines and precision roll-forming technology, we supply structural racking systems engineered for high-density warehouses, ecommerce hubs, and advanced 3PL fulfillment centers.
Enterprise procurement of industrial warehouse racking demands deep technical evaluation. Industrial structures must sustain significant static and dynamic loads under rigorous daily workflows. When sourcing OEM/ODM racking products, purchasing committees and warehouse designers must prioritize five major factors:
| Selection Factor | Engineering Standard | Key Considerations | Safety Metric |
|---|---|---|---|
| Steel Grade & Metallurgy | Q235B, Q355B (ASTM A572 Grade 50 equivalent) | Yield strength, chemical composition, impact testing | Design safety factor ≥ 1.5 to 1.65 |
| Deflection Limits | FEM 10.2.02 / RMI guidelines | Maximum deflection of beams under full load conditions | Span/200 (1/200th of horizontal span width) |
| Anti-Corrosion Surface Coaings | ASTM B117 salt spray testing compliance | Electrostatic thermoset powder coating thickness | Coating thickness of 60 to 90 microns |
| Seismic Engineering | ASCE 7 / EN 1998 (Eurocode 8) | Baseplate design, anchor bolts, bracing configurations | Variable based on regional seismic hazard zoning |
Our engineering division addresses these specifications through custom configurations. By utilizing finite element analysis (FEA) software, our 28 R&D engineers design structural profiles that maximize load-carrying efficiency while reducing steel mass, delivering optimized material savings to our global B2B clients.
Take a virtual tour of our 38,000 m² automated production facility in China. Every step of our manufacturing is integrated to ensure high reliability and consistency.
In the post-pandemic B2B landscape, logistics operations require robust supply chain resilience. Our facility in China leverages advanced Industry 4.0 frameworks to manage lead times, optimize metal fabrication processes, and guarantee quality levels. We have built partnerships with over 800 supply chain providers, securing raw steel supplies (primarily high-tensile Q235B and Q355B coils) directly from state-owned mills.
This deep vertical integration allows us to hedge against raw material price volatility, offering stable contract terms for large-scale logistics upgrades. Key supply chain capabilities include:
Equipped with specialized testing instruments, our QC division evaluates every production run to ensure compliance with global regulatory and safety standards.
The logistics industry is transitioning rapidly from traditional selective static storage racking to highly integrated dynamic automated systems. Modern supply chain operations rely heavily on data collection, real-time tracking, and automated retrieval to optimize inventory throughput. Sunli's long-term technical roadmap is focused on integrating structural hardware with robotic automated solutions.
Automated storage systems utilize stacker cranes and shuttle fleets to place and retrieve heavy pallet loads. This design allows for higher vertical racking configurations, sometimes exceeding 30 meters. This vertical expansion increases storage density by up to 100% compared to traditional reach-truck warehouse configurations.
Autonomous Guided Vehicles (AGVs) equipped with LiDAR systems navigate warehouse floors without physical tracks. Integrated into Warehouse Control Systems (WCS), these units transport goods from dock levelers directly to high-bay racking systems, lowering operational labor costs and improving facility safety.
Our upcoming product lines include IoT strain gauges and sensor nodes integrated directly into structural racking uprights. These sensors monitor load distribution and detect structural deflections or accidental impacts, transmitting alerts to safety managers' mobile devices to help prevent rack failure.
Storage requirements differ significantly across industrial sectors. We provide engineered solutions tailored to specific commercial operational environments:
Navigating global building codes and warehouse safety regulations is critical for global logistics planning. Sunli engineering designs products that comply with regional structural and safety codes:
Every shipment is provided with load-bearing certificates, material safety data sheets, and comprehensive installation manuals. Our engineering division works closely with local structural engineers to support the permitting process for new warehouse projects.
