Explore our premium grade automated systems, heavy duty racks, and smart logistic equipment engineered for optimal sub-zero industrial performance.
Why modern global enterprise supply chains require high-integrity structural storage solutions specialized for sub-zero cooling chambers.
Building and operating a cold storage warehouse requires immense capital expenditure compared to dry, ambient-temperature facilities. Because cooling costs scale with volume, operational space utilization is critical. Every cubic meter of unutilized air is a direct energy loss. Global businesses in the pharmaceutical, chemical processing, and frozen food industries are aggressively investing in ultra-high-density storage setups (like Drive-in Racking, Radio Shuttle, and ASRS).
Operating in environments down to -30°C places severe structural stress on standard mild steels. The ductile-to-brittle transition point of typical carbon steel means standard structures can fracture without warning. Consequently, professional cold chain procurement managers must only source from certified manufacturers using high-grade, impact-tested steel (like Q345B, Q355D, or Q420D) coupled with special powder coatings designed not to peel under severe thermal contractions.
Purchasing directly from Shenzhen Sunli Intelligent Logistics provides global enterprises with reliable access to custom-engineered steel racking designed explicitly for sub-zero thermal stress. This minimizes localized buckling risks and extends the structural lifecycle up to 25+ years.
Established in 2015, we are an elite manufacturer specializing in heavy-duty industrial racking and smart warehouse storage solutions.

Choosing the correct structural configuration decides the long-term ROI and daily throughput speed of your refrigerated storage.
| System Type | Space Efficiency | Access Speed (FIFO/LIFO) | Optimal Thermal Application | Automation Compatibility |
|---|---|---|---|---|
| Drive-In Racking | Very High (Up to 75%) | LIFO Only (Slower cycles) | Ideal for bulk, single-SKU food inventories | Manual Forklift Driven |
| Radio Shuttle System | Extremely High (Up to 85%) | FIFO & LIFO (Fast cycles) | Excellent for sub-zero high turnover lanes | Semi-Automated (Shuttle Carts) |
| ASRS Automated Storage | Maximum (Up to 95%) | Strict FIFO (Continuous flow) | Best for multi-SKU temperature sensitive pharma | Fully Automated Stacker Cranes & AGV |
| Selective Pallet Racking | Moderate (Up to 50%) | Direct Access (Rapid picking) | Small cold rooms / sorting spaces | Manual with smart barcode tracking |
Every step of our process, from raw material selection to structural assembly, is tracked under ISO 9001 quality guidelines.

Advanced laser and mechanical cutters deliver exact sizing.
Uniform weld beads prevent structural fatigue at freezing temperatures.
Thermal-cured powder coating protects against condensation corrosion.
We invest in advanced heavy machinery to guarantee consistency and meet the structural tolerances demanded by ASRS systems.
























We deploy 35 dedicated QC professionals along with specialized physical and chemical test instruments to verify steel and coating integrity.










How we ensure long-term structure integrity and localized seismic compliance for global industrial installations.
We run FEA structural simulation reports during the design phase, calculating natural frequencies and localized stresses based on regional seismic hazard maps. Double anchor plates are standard in high-risk zones.
Standard structural steel becomes brittle in deep freezes. We exclusively source impact-tested alloy steel (Q345B/Q355) that maintains ductile behavior and resists cracking at temperatures down to -30°C.
Refrigerated spaces run high risks of moisture condensation when gates open. Our powder coatings are applied to a strictly monitored dry film thickness (DFT), preventing oxidation under paint layers.
The convergence of heavy structural storage, warehouse management software (WMS), and autonomous robotic systems.
Human workers face physical limitations when working in sub-zero environments, which has accelerated the transition to automated warehousing systems (ASRS). Modern cold store operations rely on high-speed automated shuttle cars and laser-guided AGVs to run 24/7 dark warehouses without lighting or human heating intervals.
Shenzhen Sunli is committed to developing smart structures, including embedded racking sensor arrays that monitor temperature anomalies, localized shelf strain, and minor deflections. Our R&D team designs rack structures that seamlessly integrate with stacker cranes, radio shuttle runners, and navigation sensors, allowing rapid and precise vehicle positioning.
