Engineered high-performance machinery, logistics platforms, and material handling systems for structural warehousing optimization.
Established in 2015, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. has developed into a premier industrial pioneer focusing on dynamic structural warehousing and Automated Storage and Retrieval Systems (AS/RS). Our foundational engineering capacity leverages over 12 years of core industry experience and 8 years of professional international trade operations, allowing us to export heavy-duty infrastructure assets to complex logistical environments across North America, Western Europe, Southeast Asia, and the Middle East.
We operate from a state-of-the-art 38,000 m² manufacturing plant, integrating automated structural welding and advanced electrostatic powder-coating technologies. Our annual export footprint achieves a consistent volume between $18 million and $25 million, proving the reliance global enterprises, 3PL logistics networks, and heavy manufacturing distribution centers place upon our design accuracy.
OEM/ODM Custom Capability: We provide fully integrated steel structure layout drawings, Finite Element Analysis (FEA) load capacity calculations, electrostatic discharge (ESD) protective configurations, and customized automated shuttle integrations tailored to maximize volumetric storage densities.
Supported by a distributed network of over 800 supply chain partners, we scale production pipelines rapidly to meet critical infrastructure schedules without quality degradation.
Understanding the shift towards higher-density, automated footprint configurations in the global logistics network.
Modern international supply chain models demand unmatched spatial efficiency and operational speed. The transition towards smart warehouses has altered purchasing patterns globally. Procurement executives no longer seek simple metal storage frameworks; instead, they require complex mechanical and structural configurations that integrate with automated robotic layers. The need for global standardization (such as CE compliance, ISO9001 quality controls, and localized load certifications) has elevated specialized Chinese manufacturers into strategic engineering partners.
By leveraging advanced raw material metallurgy (chiefly Q235B cold-rolled steel structures) and automated assembly pipelines, our facility guarantees structural reliability under severe static and dynamic load conditions. For heavy industrial applications, maintaining safety standards is critical, especially when pallet configurations exceed 1,500kg per storage cell and scale to vertical heights of over 20 meters.
Inside our 38,000 m² production base: from structural raw material processing to robotic weld checks and scientific verification.
An evaluation of structural engineering properties, anti-corrosion profiles, and spatial dynamic controls.
The core material utilized throughout our structural rolling lines is high-grade carbon structural steel, predominantly Q235B and Q355B, which complies with international yield strengths and mechanical criteria. Columns are profiled utilizing continuous cold-roll forming mills to prevent internal stress concentration points. The standard load capacity per layer can exceed 3,000kg with minimal deflection. This allows industrial warehouses to build vertical systems without risking buckling or structural failures.
Additionally, our facilities maintain strict environmental and safety regulations, utilizing lead-free epoxy-polyester powder formulations. With dry-film thickness configurations strictly monitored between 60 and 90 microns, our systems resist oxidation, acid/alkali exposures, and scratching in challenging warehouse environments.
Modern supply chains require more than static shelves. Integrating Automated Guided Vehicles (AGV) and AS/RS systems increases retrieval velocities, minimizes picking errors, and reduces overhead operating expenses. Utilizing laser-navigation (LIDAR) scanners, dual-drive motors, and DC24V power systems, our AGVs transport payloads up to 1,500kg with sub-millimeter tracking accuracy.
These automated systems interface directly with Warehouse Management Systems (WMS) and Warehouse Control Systems (WCS) via standard industrial networks. This provides supply chain managers with real-time inventory visibility and reduces manual handling risks in high-throughput fulfillment centers.
How digital twins, advanced AI controls, and sustainable logistics shape the next decade of material handling.
As logistics operations face increasing labor shortages and demands for rapid order processing, the manufacturing sector must evolve. The next phase of structural material handling relies on the integration of Artificial Intelligence (AI) and Cyber-Physical Systems (CPS). By embedding real-time pressure transducers and structural sensors into heavy rack frames, systems can monitor structural integrity and dynamically alert operators to potential overload stresses before failures occur.
Furthermore, energy conservation has become a major design requirement for warehouse operators. Our R&D division is focused on developing lightweight structural profiles that maintain yield strength while reducing total steel consumption. Simultaneously, we are building smart kinetic energy recovery systems for automated stacker cranes and AGVs, enabling them to recharge onboard supercapacitors during braking phases, which cuts operating power requirements by up to 25%.
The Evolution of Warehouse Navigation: The transition from physical tape guidance to SLAM (Simultaneous Localization and Mapping) and Visual Inertial Odometry (VIO) allows AGV networks to operate in complex spaces without structural modifications to the facility floors. This ensures rapid system deployment and flexibility for changing facility footprints.
How we maintain zero-defect standards for international distribution projects.
To operate reliably across the world's most regulated logistics hubs, our equipment meets stringent global building standards. Shenzhen Sunli Intelligent Logistics Equipment maintains full compliance with FEM 10.2.02 (European Racking Guidelines), RMI (Rack Manufacturers Institute of North America specs), and AS4084 (Australian Steel Storage Racking standards). This guarantees our structural systems conform to regional seismic design requirements, protecting both operators and assets.
Our quality assurance program is managed by a team of 35 dedicated QC professionals. They oversee a multi-stage verification protocol that includes raw steel chemical analyses, weld non-destructive testing (NDT), dry film thickness audits, and static load deflection verification. We ensure each shipment is backed by clear documentation, mill certs, and installation support guides.
Localized Logistics Support: We collaborate with engineering partners and local site contractors across North America, Europe, and Asia to manage regulatory approvals, customs clearance, site assembly, and structural sign-off. This hands-on oversight reduces deployment delays and ensures our products fit seamlessly into our client's existing warehouse footprints.
Comprehensive ESD Protection: For electronics manufacturing plants, semiconductor storage facilities, and precision medical cleanrooms, we offer specialized conductive coatings and electrostatic grounding systems to protect sensitive electronics from static discharges during handling and storage.
Technical answers to critical procurement questions regarding industrial steel racking and AGV system design.
Our primary manufacturing lines utilize Q235B and Q355B carbon structural steel. Q235B is preferred for industrial racking due to its optimal balance of yield strength, ductility, and welding characteristics. It provides the necessary structural resilience to withstand heavy loads and seismic shifts without brittle failures, complying with international structural standards.
Our AGVs utilize advanced LIDAR-based laser navigation, allowing the vehicles to construct real-time mapping zones. Equipped with safety obstacles scanners, they detect surrounding workers, vehicles, and structures, slowing down or stopping within milliseconds. This reduces workplace injuries, product damage, and structural impacts compared to manual forklift operations.
All Shenzhen Sunli solutions are certified to meet major international standards, including CE certification for electromagnetic compatibility and structural safety, ESD protection standards for electro-sensitive workspaces, and ISO9001:2015 quality management procedures. This guarantees conformity with local safety codes in North America, Europe, and Asia Pacific.
