In modern temperature-controlled supply chains, warehouse operations are faced with the challenge of optimizing space while ensuring structural safety under extreme conditions. Operational spaces maintained at temperatures down to -30°C require specialized storage configurations. In these environments, conventional structural steel is prone to low-temperature embrittlement, which increases structural vulnerability under heavy dynamic loads.
As a leading exporter of cold storage racking systems in China, we design systems engineered to perform reliably in demanding environments. By utilizing optimized cold-rolled steel grades, advanced zinc-rich protective coatings, and seismic-resistant configurations, we provide global logistics operators, food distributors, and pharmaceutical companies with systems that maximize storage density, ensure operational safety, and lower the Total Cost of Ownership (TCO).
Shenzhen Runda Racking Manufacturing Co., Ltd. is a manufacturer specializing in heavy-duty industrial shelving and high-density warehouse storage systems. Established in 2015, we bring over 11 years of industry experience and 9 years of active global export operations. We deliver engineered racking systems to logistics hubs, distribution centers, and manufacturing plants worldwide.
Operating from a modern 35,000 square meter production facility, our operations are powered by a robust network of over 1,200 supply chain partners. Our primary markets span North America, Western Europe, Southeast Asia, and the Middle East, where we serve industrial distributors, third-party logistics (3PL) operators, and enterprise buyers. Quality and innovation drive our core philosophy: we maintain strict quality control through full-process sampling inspection, raw material stress testing, and load-bearing verification. Last year alone, our R&D team updated and released over 120 new storage designs.
Our production processes combine automated efficiency with strict quality control. From sourcing raw steel to final export loading, each stage is tracked to ensure standard compliance. Our structural components are manufactured using CNC punching, laser cutting, and automated powder coating systems, ensuring precise dimensions and consistent structural integrity.
Cold storage engineering is transitioning from traditional static storage structures to dynamic, high-density systems. In sub-zero environments, optimizing storage density directly reduces thermal cooling costs. Our technology roadmap focuses on three main developments:
Standard carbon steel undergoes a transition to brittle behavior at low temperatures. We utilize optimized low-temperature structural steel grades, including Q355D and specialized micro-alloyed steels, which retain their impact toughness and ductile performance at temperatures down to -40°C.
Humidity changes in cold storage entry zones lead to condensation. Our systems use hot-dip galvanized coatings (compliant with ASTM A123) and multi-layer epoxy powder systems to prevent oxidation and protect structural surfaces.
We design structural framing engineered to integrate with Automated Storage and Retrieval Systems (AS/RS) and automated shuttle carts, ensuring the tolerances and alignment stability required for high-speed operation in sub-zero facilities.
Storage requirements vary across cold chain industries. We design storage systems tailored to different product types, inventory rotation models, and ambient conditions.
| Industry Vertical | Operational Challenges | Recommended Racking System | Benefits & Space Efficiency |
|---|---|---|---|
| Food & Beverage Logistics | High volume rotation, strict FIFO (First-In, First-Out) control, FDA packaging rules. | Gravity Flow & Pallet Runner/Shuttle Systems | Up to 85% volume utilization; clean FIFO rotation, minimal pallet damage. |
| Pharmaceutical Cold Storage | Precise temperature zoning (-20°C to -80°C), batch control, high security. | High-Bay AS/RS Automated Systems & Mobile Racking | Maximizes cubic density; integrates with WCS/WMS for real-time tracking. |
| 3PL Distribution Centers | Varied pallet loads, multi-client access, frequent inventory changes. | Drive-In & Double Deep Selective Pallet Racking | Flexible configuration; low capital investment with high storage capability. |
| Agricultural Freezers | Seasonal inventory peaks, bulky pallets, high ambient moisture. | Heavy-Duty Push Back & Cantilever Racking | Robust support for irregular bulk pallets; simplifies structural access. |
Industrial buyers prioritize structural reliability, safety standard compliance, and cost efficiency. Our engineering team designs and manufactures systems to meet these requirements.
Standard carbon steel (like Q235B) performs well at ambient temperatures but can become brittle in cold storage environments. We recommend and use Q355D steel for low-temperature applications. It undergoes impact testing at -20°C to ensure its toughness and load capacity are maintained under sub-zero conditions.
When cold storage doors cycle, temperature fluctuations cause condensation to form on metal surfaces. To prevent rust, we offer hot-dip galvanizing and electrostatically applied epoxy coatings. These treatments provide a moisture barrier, preventing rust from forming on columns, braces, and beam connectors.
Industrial racking installations must comply with regional building regulations and seismic safety codes. We work with engineering partners to verify that our exports meet these local requirements.
Our designs are calculated in accordance with EN 15512 and FEM 10.2.02 standards, ensuring compliance for deployment in European Union markets.
For North American facilities, designs comply with RMI (Rack Manufacturers Institute) specifications, including local seismic design requirements.
Our heavy-duty frames are engineered to meet the structural tolerances, deflection limits, and safety margins defined by AS 4084-2012.
