Engineered to meet stringent EU safety standards, maximizing vertical space efficiency.
Established in 2015, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. is a premier structural engineering manufacturer specializing in heavy-duty industrial racking systems, custom mezzanine platforms, and dynamic smart-warehouse automation hardware. Operating from our advanced 38,000 m² digital manufacturing facility, we integrate 12+ years of structural storage design expertise with 8 years of international trade operations to design, build, and deliver high-performance structural systems worldwide. Generating $18 million to $25 million in annual export revenue, our core operational footprints span high-regulatory zones including North America, Western Europe, Southeast Asia, and the Middle East.
Optimizing three-dimensional space utilization and structural resilience for advanced global supply chains.
Modern commercial real estate values demand efficient vertical footprint utilization. Structural steel platforms from Sunli elevate logistics layouts, providing multi-tiered load-bearing spaces without requiring external building expansions.
Every industrial structural platform requires precise mechanical modeling to secure regional building permits. We conduct advanced Finite Element Analysis (FEA) to verify that structural load paths safely support operations under dynamic stresses.
Our heavy-duty Q235B platforms serve as the physical foundation for autonomous material handling. By combining structural mezzanines with AGVs, Laser Guided Forklifts, and Automated Radio Shuttle systems, we help facilities scale storage density and processing throughput.
Adapting steel storage architectures to distinct regional regulations, supply chain structures, and environmental demands.
Standards Met: RMI (Rack Manufacturers Institute) Specifications & AISI S100.
Our structures satisfy strict ASTM and ANSI codes for high-bay logistics centers and local retail spaces, incorporating heavy-duty structural steel shapes designed to withstand dynamic high-cycle material handling processes.
Standards Met: EN 1090-2 (Execution of Steel Structures) & CE Marking.
We comply fully with EC directives for steel structures. Our EN 1090-certified welding and traceable steel supplies simplify the inspection and permitting process for European contractors and project managers.
Standards Met: ISO 9001, Seismic-Resistant Custom Coatings.
We supply high-humidity coastal ports and high-heat arid regions with high-durability hot-dip galvanized finishes and custom-thickness thermosetting powder coatings to protect structures against corrosion.
Step-by-step production flow powered by automated fabrication machinery to ensure structural precision.
Mitigating supply chain risks through comprehensive field verification and structural certifications.
We provide full structural site evaluations using high-precision laser scanners, documenting existing slab capacities, seismic design classes, and clear overhead dimensions before final structural fabrication begins.
Our structural engineers design baseplate details and brace connections to suit specific regional seismic codes (such as ASCE 7 in North America and Eurocode 8 in Europe).
We supply precise, detailed installation plans, assembly drawings, and structural load plaques to guide onsite installation and ensure compliance with local building safety requirements.
Our 35-person quality control team utilizes certified testing instruments to verify the performance of every components.
Engineered configurations designed for specific industry challenges and operating conditions.
Standard carbon steel becomes brittle at low temperatures. We utilize certified Q235B structural steel, finished with low-temperature powder coatings or hot-dip galvanization, to prevent embrittlement and maintain load capacity in environments down to -30°C.
Designed to support high foot traffic and mechanical equipment, our multi-level mezzanine structures incorporate safety features like structural stairs, handrails, kickplates, and mesh panels to ensure safe operations alongside automated sortation systems.
For assembly lines with heavy point loads, we design heavy-duty hot-rolled steel platforms. These structures feature custom beam spans and thick steel gratings to carry localized loads up to 2000 kg/m² while minimizing floor vibration.
Investing in sustainable engineering and digital integration to support the next generation of logistics platforms.
We are developing structural systems integrated with strain-gauge sensors. These sensors track changes in structural load patterns and stress, helping operators prevent overloads and optimize safety across multi-level mezzanine platforms.
In line with global environmental goals, we have updated our powder-coating lines to reclaim overspray, reducing chemical waste by up to 98%. We are also working with our steel suppliers to source low-carbon steel profiles for all new fabrications.
To help companies adapt to changing business demands, our engineering team designs modular, bolt-together mezzanine connections. These configurations allow panels and beams to be disassembled, moved, or expanded with minimal downtime.
Answers to common structural engineering, compliance, and international shipping questions.
We provide full structural weld documentation, Mill Test Certificates (MTC) detailing chemical and physical composition, and official CE Declarations of Performance (DoP). These documents confirm that our structural components meet the performance requirements of the EN 1090-1 and EN 1090-2 execution standards.
Our mezzanine platforms are customized to meet specific application requirements. Standard load capacities range from 300 kg/m² for basic hand-pack picking operations up to 2,000 kg/m² for heavy industrial setups, automated storage, or equipment platforms.
Our 35-person QC team conducts raw material checks, weld-joint ultrasonic non-destructive testing (NDT), dry-film coating thickness verification, and mechanical load-path calculations. We pre-assemble critical structural connections in our facility to verify tolerances prior to final packing and shipping.
Yes. Our engineering team designs platform structures to align with automated logistics systems, including Automated Guided Vehicles (AGVs), laser-guided forklifts, automated shuttle systems, conveyor lines, and vertical lifts.
