Engineered structural steel racking configurations designed to maximize volumetric efficiency and material handling workflows.
A global authority in high-performance storage architectural fabrication and intelligent material handling ecosystems.
Established in 2015, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. has developed into a premier global designer, manufacturer, and exporter of high-load heavy-duty industrial storage racks and dynamic automated warehouse environments. Utilizing a specialized manufacturing base extending across 38,000 m², Sunli matches industrial-scale capability with rigorous precision engineering. By fusing 12 years of structural engineering design experience with 8 years of complex international trade operations, we enable large-scale enterprises to achieve optimized physical operational capacity, compliance-focused storage, and high-efficiency material logistics.
Our global export infrastructure commands an annual outbound trade footprint ranging between $18 million and $25 million. We maintain strategic design compliance, manufacturing capacity, and deployment pipelines customized for key international logistics centers across North America, Western Europe, Southeast Asia, and the Middle East. Through advanced physical simulations, structural analysis, and robotic fabrication, we supply durable structural steel solutions to global supply chains.

Analyzing the shift from manual static racking systems to highly dynamic automated storage configurations.
Rising industrial land valuations require warehouses to optimize vertical storage. Modern multi-tier mezzanine floor platforms and double-deep racking configurations utilize footprint efficiency to maximize volume capacity without increasing building area.
Modern supply chain logistics rely heavily on AGVs, AMRs, and automated laser-guided forklifts. Transitioning to automated handling reduces human labor costs, increases product sorting throughput, and minimizes product damage within narrow aisle corridors.
Seismic risk mitigation has become essential for high-rack structures globally. Compliance with RMI (Rack Manufacturers Institute) and FEM guidelines is standard protocol, ensuring configurations survive structural loading dynamics and environmental events.
How Sunli designs tailored storage platform solutions for complex distribution facilities and specialized supply chains.
High SKU counts and rapid order fulfillment cycles require dynamic modular racking configurations. Sunli designs adjustable medium-to-heavy shelving architectures that integrate with sorting lines, allowing logistics providers to quickly adapt to shifting retail product lines.
Sub-zero refrigeration environments require anti-corrosive, structurally stable materials. Sunli cold-rolled Q235B structural steel undergoes hot-dip galvanization or specializes in anti-rust powder coatings to maintain load rating integrity and prevent surface degradation at -30°C.
Storing tooling, dies, and raw sheet materials requires heavy-load structural rack arrays. Utilizing structural uprights, heavy cross-beams, and reinforced safety pins, we build storage arrays capable of holding 2,000 kg per pallet layer safely.
From finite element analysis (FEA) to robotic steel production—ensuring high reliability for structural storage platforms.
Our engineering department leverages advanced computer simulations and physical modeling to build reliable industrial storage platforms. The structural safety of a multi-tier mezzanine floor or a 25-meter-tall AS&RS storage system depends on calculating load stresses, weld point fatigue, and seismic anchoring forces. We utilize a quality control team of 35 QC professionals to run steel coupon tensile tests, weld ultrasound inspections, and micrometer thickness checks on our powder coatings, ensuring all components resist corrosion and premature wear.
By utilizing cold-rolled profile forming lines and automated multi-pass robot welding systems, we manufacture high-tolerance structural profiles. This level of fabrication precision ensures that when components arrive at a job site in North America or Western Europe, they assemble quickly with tight bolt connections, reducing installation labor costs.
Supporting international deployments through engineering compliance, certified sourcing, and local installation partners.
All structural designs comply with international engineering directives, including CE validation for European corridors and ISO9001 quality management guidelines. This simplifies building permit approvals for structural steel installations.
Our engineering team designs custom structural profiles, frame configurations, and safety accessories to meet specific architectural requirements, building columns, and fire safety codes.
With 8 years of export trade experience, we coordinate shipping, customs, and delivery logistics, providing detailed structural drawings and video guides to simplify on-site assembly.
Sunli’s forward-looking framework for integrating real-time telemetry and robotics into industrial racking systems.
Refining mechanical tolerances on running tracks to support reliable laser-guided shuttle and automated AGV operation.
Developing structural load sensors to monitor load weight distribution and alert warehouse managers of overload risks.
Testing hybrid eco-friendly powder formulations to improve chemical and impact resistance in harsh industrial environments.
Combining heavy-duty racking structural design with robotic material transport systems for high-throughput operations.
Detailed engineering and procurement guidelines for global industrial storage projects.
We primarily use Q235B and Q355B cold-rolled structural carbon steel. These steel grades provide balanced tensile strength, structural elasticity, and weldability. They are certified for load-bearing reliability under standard warehouse temperatures as well as low-temperature cold storage environments.
Our engineering team conducts structural static calculations and Finite Element Analysis (FEA) using 3D modeling software. We evaluate uniform static loads, point loads, and dynamics like forklift traffic. In our quality control lab, we test real-world stresses using hydraulic testers, ensuring each system meets safety margins of 1.5 to 2.0 times rated capacity.
We offer two main protective coatings: a high-durability electrostatic thermosetting powder coating for standard indoor dry warehouses, and hot-dip galvanization (conforming to ISO 1461 standards). Hot-dip galvanizing protects structures in highly humid, chemical-exposed, or outdoor settings by coating both interior and exterior steel surfaces.
Yes. We design and manufacture structures to match regional regulatory frameworks. We comply with RMI standards in the United States, FEM 10.2.02 codes throughout Europe, and AS4084 guidelines across Australia and Oceania. Our engineering documentation and structural calculation reports are available for local construction permits.
Standard project configurations typically ship within 20 to 30 days following engineering drawing sign-off. Highly customized systems, such as automated AS&RS infrastructures or integrated multi-level mezzanine assemblies, require 35 to 50 days to complete customized tooling, robotic profiling, multi-step welding, and surface treatment.
