Premium selection of industrial mezzanine structures, heavy-duty gravity flow racks, and autonomous laser-guided logistics solutions.
A trusted global leader in structural engineering, automated warehousing integration, and high-performance material handling logistics.
Established in 2015, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. has developed into a premier global manufacturing pioneer of high-performance heavy-duty industrial racking, automated storage and retrieval systems (AS/RS), and smart warehouse storage solutions. Leveraging a dynamic foundation of 12 years of core industry manufacturing experience and over 8 years of seamless international trade expertise, we cater directly to demanding Fortune 500 logistics hubs, large-scale 3PL providers, industrial distribution channels, and global e-commerce fulfillment networks.
Operating from our modern state-of-the-art 38,000 m² production plant, we run high-capacity automated rolling, bending, punching, and welding lines. Sunli maintains an impressive annual export volume ranging between $18 million and $25 million, consistently serving key markets throughout North America, Western Europe, Southeast Asia, and the Middle East. Our product development pipeline is driven by 28 highly skilled R&D engineers who continuously adapt designs to evolving structural safety codes, introducing more than 120 product iterations and structural improvements annually.
Quality assurance is embedded in our manufacturing DNA. Our dedicated division of 35 QC inspectors guarantees that every load-bearing rack configuration undergoes rigorous engineering validations, from raw steel chemical analysis to paint finish salt spray tests. This technical rigor allows us to provide comprehensive OEM and ODM support, providing structural steel configurations that match our customers' precise loading patterns and global safety requirements.

Global logistics managers face rising land costs. Standard industrial racking must optimize vertical space. Implementing multi-tier steel mezzanine systems and carton flow systems can increase storage density by up to 150% without expanding the warehouse footprint.
Industrial storage requires strict load-bearing parameters. Sunli's selective racking configurations use Q235B and Q355B cold-rolled steel profiles. Dynamic finite element analysis (FEA) ensures safety margins and minimizes structural deflection under maximum load.
Modern supply chains require automated hardware support. Integrating laser-guided autonomous forklifts (AGVs) requires high tolerances in rack straightness and levelness. Our production tolerances align with FEM 10.2.02 and RMI standards to ensure smooth AGV integration.
The industrial storage sector is transitioning from static steel structures to dynamic, software-integrated logistics nodes. Racking structures are no longer just passive frames; they serve as the backbone for robotic shuttles, pallet runners, and autonomous material handling systems. Modern supply chain operations focus on optimizing cost per pallet position, vertical space utilization, and safety compliance.
The foundation of any structural rack is raw material quality. Using high-tensile, cold-rolled steel coils allows manufacturers to reduce gauge thickness without sacrificing load-bearing capacity. Automated roll-forming lines shape upright columns with precision lock-joint patterns, ensuring secure connections with horizontal box beams. High-precision welding robots maintain consistent weld penetration, preventing stress points under heavy loads.
Industrial racking must withstand diverse conditions, from refrigerated cold storage to humid regional ports. Modern electrostatic powder coating lines apply a uniform epoxy-polyester layer, typically 60 to 80 microns thick, which is heat-cured to resist mechanical impacts and chemical exposure. Pre-treatment processes, including multi-stage acid pickling and phosphating, ensure strong adhesion and rust resistance.
Safety is critical in high-density storage. Dynamic operations can result in accidental forklift collisions. Installing rack column protectors, guide rails, and heavy-duty barrier systems helps isolate critical structural uprights from impacts. Under seismic design guidelines like RMI MH16.1, engineering calculations must account for local seismic zone categories, ground soil conditions, and concrete slab strength to prevent structural failure.
Common questions from procurement engineers and logistics managers regarding design, safety, and compliance.
Standard heavy-duty selective pallet racks typically support load capacities ranging from 1,000 kg to 4,000 kg per level, depending on the beam profile, upright frame thickness, and structural steel grade (such as Q235B or Q355B). Systems can be customized to support higher load configurations.
Warehouse mezzanine platforms leverage unused vertical overhead space, creating distinct floor levels. They can double or triple storage capacity without requiring building expansions. These platforms are engineered to integrate with manual storage, conveyors, or sorting systems.
Our design and manufacturing processes comply with key global standards, including CE certification, ISO 9001 quality management systems, FEM 10.2.02 European Code, and RMI design specifications in North America.
Laser-guided forklifts and AGVs provide consistent, driverless internal transport. Operating with obstacle detection, they help reduce product damage, lower labor costs, and maintain high throughput in complex industrial environments.
