How high-density automation and heavy-duty structural engineering are reshaping international supply chains, driving spatial efficiency, and reducing operational overhead.
In modern industrial hubs, spatial limitations require dynamic high-bay stackable structures. Implementing pallet runner shuttle racking and AS/RS automated platforms increases storage density by up to 60% compared to traditional single-tier layouts.
Automated high-speed stacker cranes and laser-guided robotic systems lower warehouse labor overhead. Shifting to high-bay storage also reduces lighting, heating, and cooling footprints, helping operators meet corporate sustainability targets.
Using standard Q235 cold-rolled steel and anti-corrosive powder coatings extends the working life of storage systems in challenging settings like cold storage or high-humidity facilities, ensuring consistent operation and supply chain reliability.
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.
From premium structural steel coils to precision molding, automatic welding, and high-quality spray coating lines.
Our dedicated 35 QC professionals use precise testing methods to ensure structural load capacity, weld integrity, and coating durability.
We design our products to meet strict international standards, ensuring safe installation and compliance across different regions.
Our engineering standards align with FEM 10.2.02 (Europe), RMI standards (North America), and AS4084 (Australia). This ensures safety and reliability under local wind, seismic, and occupational regulations.
We perform full finite element analysis (FEA) to calculate seismic response coefficients for regional installations, optimizing beam configurations for safe structural performance.
Our manufacturing processes are certified to CE and ISO 9001:2015. We offer specialized finishes like food-safe FDA compliant powder coatings and ESD protection for electronics manufacturing.
We design custom racking systems to meet the specific operational demands of key industrial sectors.
High-density racking configurations that maximize storage density while allowing quick access to a high volume of SKUs.
Strong steel structures built to handle heavy, irregular loads and tooling dies, utilizing selective high-capacity framing.
Galvanized steel finishes and dense racking designs optimized to withstand temperatures down to -30°C while maximizing cold storage space.
Dynamic, multi-level shelving designed for quick manual picking, high inventory turnover, and integration with conveyor lines.
How our engineering team is integrating smart technologies and sustainable materials into next-generation industrial storage.
We design our structural racks for precise interaction with automated cranes, shuttles, and laser-guided forklifts, keeping dimensional tolerances tight to support autonomous operations.
Our R&D team is testing digital strain gauges and angle sensors integrated into upright supports. These provide real-time alerts for overloading or accidental impact damage, improving facility safety.
To support sustainability goals, we are incorporating high-strength recycled structural alloys and low-VOC powder coatings, reducing the environmental footprint of our products.
Technical details regarding design calculations, material specifications, and global logistics options.
We primarily use premium cold-rolled Q235B and Q355B structural carbon steel. Q355B steel is chosen for heavy-duty components and high-bay uprights because of its higher yield strength, ensuring stable performance under heavy load requirements.
Our engineering team conducts structural testing using Finite Element Method (FEM) software. Each component design is verified through physical compression, shear, and deflection testing in our onsite laboratory before volume production.
Yes. We engineer customized configurations for regions with seismic activity. Based on local building codes, we design larger base plates, heavy-duty floor anchoring systems, and enhanced bracing profiles to manage dynamic loads safely.
We apply an electrostatic thermosetting epoxy powder coating. The steel undergoes a multi-stage wash and zinc-phosphate pretreatment, followed by curing at 200°C to create a scratch-resistant, anti-rust surface. Hot-dip galvanized finishes are also available for outdoor or high-humidity environments.
We offer full OEM and ODM services. Our R&D team provides CAD layouts, 3D models, and technical specifications tailored to your specific warehouse dimensions, load requirements, pallet handling equipment, and material types.
Standard manufacturing times range from 20 to 35 days, depending on project scale and complexity. Orders are securely packed using steel banding and protective wrapping to ensure safe sea or rail transport to destination ports.
