Explore our foundational range of heavy-duty storage systems designed for scalability, safety, and operational excellence.
Established in 2015, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. stands as a premier manufacturer specialized in heavy-duty industrial racking and smart warehouse storage systems. Operating from our advanced, state-of-the-art production base spanning over 38,000 m², we integrate structural steel engineering with automated logistics layouts.
With more than 12 years of structural engineering experience and 8 years of global export compliance history, we support complex supply chain setups across North America, Western Europe, Southeast Asia, and the Middle East. Through scalable OEM/ODM configurations, we help organizations optimize floor space and drive workflow automation.
The Evolution of Green Logistics, Decarbonized Steel Systems, and Sustainable Global Supply Chains
Modern distribution centres prioritize structural steel produced via high-efficiency methods that emit less carbon, lowering the overall embodied carbon of the warehouse frame.
Using thermosetting polyester coatings free of heavy metals and VOCs eliminates toxic off-gassing, keeping internal storage environments safer for products and staff alike.
Utilizing high-tensile structural steel improves safety margins and limits long-term wear. This reduces structural replacement rates, saving resources and lowering costs.
Sustainable operations are a key priority for modern supply chains. Global supply chain strategies now focus closely on Scope 3 emissions, which cover indirect value chain emissions. Choosing racking infrastructure that uses recycled steel and energy-efficient manufacturing helps logistics hubs align with green building standards like LEED and BREEAM.
Beyond material selection, structural durability plays an important role in sustainability. Implementing high-density systems like AS/RS and Push-Back configurations reduces a facility's footprint. This optimization lowers energy use for heating, cooling, and lighting, minimizing overall environmental impact.

Addressing the strict design, safety, and supply chain requirements of high-capacity logistics operators
Modern corporate procurement goes beyond comparing initial cost metrics. Global enterprises need structures that are resilient, configurable, and compliant with safety codes like EN 15512 and RMI standards.
Our engineering team designs systems tailored to regional conditions, accounting for soil characteristics and local seismic activity. By combining precise structural planning with high-performance finishes, we ensure long-term stability and performance for demanding operations.
Comprehensive verification workflows checking structural design, coating thickness, and impact strength
Our quality control program covers every stage of production, beginning with structural verification of incoming cold-rolled steel coils. Our QA lab tests weld integrity using non-destructive methods to verify joint strength under load.
We use digital thickness gauges and impact testers to verify paint adhesion and chip resistance on our powder-coated surfaces. We also test post-installation stability with digital bolt-drawing and laser-alignment tools, verifying load performance to keep your warehouse operating safely.
Exporting industrial equipment globally requires adherence to regional certifications and standards. We work closely with site managers and third-party inspectors to ensure all structures align with local safety codes and seismic requirements.
From initial CAD designs to shipping and customs clearance, our team manages the process to ensure on-time delivery. We provide clear installation manuals, anchor testing data, and maximum load plates to keep your operations compliant.
Designing the future of intelligent warehouse storage systems
Developing low-friction racking systems optimized for high-speed automated shuttles (AS/RS), maximizing throughput and density.
Providing detailed 3D structural models to help operators simulate load variations and optimize storage density within their WMS.
Working to source structural steel produced with lower carbon emissions, supporting the industry's shift toward greener logistics.
Technical answers to common questions about heavy-duty storage design, certifications, and load configurations
To design an efficient layout, we require the warehouse floor plan, clear ceiling height, pallet dimensions (width, depth, height), total weight per load, forklift configuration (turning radius), and any regional seismic design codes.
Our ESD-safe systems feature conductive ground paths and specialized anti-static powder coatings. This prevents static buildup, protecting electronic components and sensitive items during handling and storage.
For cold rooms and high-humidity facilities, we recommend hot-dip galvanized steel or specialized outdoor-grade powder coatings. This provides long-term corrosion resistance and ensures structural integrity in temperatures below freezing.
Our engineering team uses specialized software to analyze soil and seismic conditions. We custom-engineer upright profiles, baseplates, and anchorage details to meet local regulations and keep the installation stable.
