Modern global supply chains operate at unprecedented velocities, placing structural demands on distribution centers and heavy-duty industrial storage arrays that go far beyond basic space utilization. Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. (established in 2015) is a premier manufacturer specializing in heavy-duty industrial racking and smart warehouse storage systems. Operating from our advanced 38,000 m² automated production plant, we combine 12 years of core engineering experience and 8 years of international trade expertise.
Sunli's annual export revenues range between $18 million and $25 million, serving leading enterprise clients in North America, Western Europe, Southeast Asia, and the Middle East. Through strict structural calculations, advanced metallurgy, and seamless robotic AGV and AS/RS integration, we ensure that every system delivers long-term durability and safety.
Fully customizable structural configurations utilizing high-grade cold-rolled steel. Certified load capabilities of up to 4000kg per level, engineered for high-turnover logistics centers.
Seamless engineering integration with autonomous forklifts and automated shuttles. Equipped with multi-line Lidar guidance and 6-8H runtime profiles to maximize automated throughput.
Industrial platforms designed using Q235B perforated panels and heavy supports, doubling vertical floor utility without requiring expensive building expansions.
Industrial structural integrity is determined by manufacturing precision. At Sunli, our engineering team utilizes high-precision roll-forming lines to achieve cross-sectional thickness tolerances within ±0.1mm. Our powder-coating systems apply an electrostatic epoxy-polyester layer of 60 to 90 microns, which is verified using cross-cut and impact testing. This ensures exceptional corrosion resistance, making our storage racks suitable for environments ranging from temperature-controlled warehouses to cold-storage facilities.

|---|---|---|---|
| Heavy-Duty Pallet Racking | Q235B / Q355B Hot-Rolled | Up to 4,000 kg / Level | Electrostatic Epoxy Powder Coat / CE Certified |
| Industrial Mezzanine Flooring | Q235B Perforated Panels | 300 - 1,000 kg / m² | Hot-Dip Galvanized / ISO 9001 |
| Long Span Shelving Systems | Cold-Rolled Structural Steel | 200 - 800 kg / Level | Anti-Rust Double Powder Coating / ESD Protection |
| SL-AGV-1000BY-01 Navigation Unit | Reinforced Structural Chassis | 1,000 kg Dynamic payload | Multi-Line Lidar / Laser Obstacle Avoidance |
Sunli's quality assurance process is managed by a team of 35 dedicated QC professionals. We perform comprehensive inspections on all materials, from raw coil verification to final weld non-destructive testing (NDT). Our structural calculations comply with European Federation of Materials Handling (FEM) 10.2.02 standards and the American Rack Manufacturers Institute (RMI) MH16.1 specifications.
This systematic quality control ensures that our systems are built for long-term safety. By testing structural welds and assessing finish adhesion under high-stress conditions, we deliver storage configurations designed to minimize downtime, prevent structural failures, and lower the total cost of ownership (TCO) for global supply chain operations.
We use Q235B and Q355B structural steel grades. These materials are selected for their optimal balance of tensile strength and ductility. Every batch undergoes chemical composition and load-bearing analysis to ensure performance integrity under maximum load limits.
Yes, our R&D engineering division offers full OEM and ODM services. We can customize dimensions, load configurations, powder coating colors, and integrate systems with automated logistics tech (AS/RS and AGV navigation) based on your site plans.
Our AGV systems, including the SL-AGV-1000BY-01, feature multi-line Lidar, physical safety bumpers, and automated obstacle detection sensors. These components enable the units to navigate busy facility floors safely while handling continuous 6-to-8-hour work cycles.
