High-performance industrial shelving and specialized storage solutions manufactured to international cold chain and office standards.
Why standard warehousing systems fail in cold rooms and how specialized materials preserve structural integrity under sub-zero thermal stresses.
Standard carbon steel becomes brittle and susceptible to micro-fractures when temperatures drop below 0°C. In high-density cold rooms operating at -18°C to -30°C, we employ high-grade structural alloys like Q355D and Q355E. These steels undergo Charpy V-Notch impact testing at sub-zero baselines to guarantee flexibility, high yield limits, and dynamic load resilience under thermal contraction forces.
Condensation is the primary catalyst for rust in cold chain facilities. When materials move between ambient and chilled zones, moisture forms rapidly. Our specialized industrial finish utilizes multi-stage epoxy-polyester powder thermosetting, cross-linked to repel moisture ingress. Hot-Dip Galvanizing (HDG) to BS EN ISO 1461 standards is also applied for severe environment components, ensuring 50+ year corrosion resistance.
Metals shrink in sub-zero temperatures. In a 50-meter-wide cold storage facility, shrinkage can amount to several centimeters, leading to misalignment, bolt loosening, and racking strain. Luyuan engineers utilize structural slip-joints, slot-hole upright connections, and high-tensile Grade 8.8 structural fasteners configured to absorb physical expansion and contraction cycle dynamics without sacrificing load capacity.
| Steel Classification | Temperature Threshold | Min Yield Strength (MPa) | Impact Test Baseline (Joule) | Best Application |
|---|---|---|---|---|
| Q235B / SS400 | 0°C to Ambient | 235 | 27 J at 20°C | Standard Warehouse Mezzanines & Shelves |
| Q355B / ASTM A572 | -10°C to 0°C | 355 | 34 J at 0°C | Chilled Storage (Fruits, Dairy, Vegetables) |
| Q355D / EN10025 | -20°C to -10°C | 355 | 34 J at -20°C | Deep Freeze Rooms (Meat, Seafood, Prepared Meals) |
| Q355E / Low Temp Special | -30°C to -20°C | 355 | 34 J at -40°C | Industrial Blast Freezers & Cryogenic Facilities |
Guangdong Luyuan Import and Export Trading Co., Ltd. is a professional warehouse storage rack manufacturer and global supplier specializing in industrial racking systems, warehouse shelving solutions, and customized storage equipment.
Established in 2016, the company operates a modern production facility covering 18,000㎡, integrating product design, manufacturing, quality inspection, and international trade services. With annual export revenue reaching approximately USD 12 million and 8 years of export experience, Luyuan has developed strong capabilities in serving global customers with reliable warehouse storage solutions.
The company has more than 12 years of industry experience, providing high-quality pallet racks, heavy duty racks, cantilever racks, mezzanine systems, supermarket shelving, and customized warehouse solutions. We serve warehouse operators, logistics companies, manufacturing enterprises, retail chains, construction contractors, and storage equipment distributors worldwide.
We deploy state-of-the-art CNC, bending, and automatic laser cutting machines to guarantee structural precision and design tolerances.
Analysing supply chain optimizations, spatial economics, and localization challenges for cross-border logistics infrastructures.
Cold storage construction represents one of the highest capital expenditures (CapEx) in warehousing due to refrigeration insulation costs. Buyers must maximize pallet densities to minimize cubic volume refrigeration waste. Guangdong Luyuan develops tailored Drive-In, Shuttle Rack, and Mobile Racking systems that boost volumetric utilization by up to 85% compared to selective racking.
Cold storage racks carry extreme weight loads in consolidated heights. Standard configurations cannot withstand seismic movements. We design systems to comply with international regulatory codes: RMI (USA), FEM 10.2.02 (Europe), and AS4084 (Australia). Seismic calculations determine anchor plate thicknesses, base isolates, and high-frequency structural diagonal cross-bracing styles.
Building racks at sub-zero temperatures presents unique execution problems: standard pneumatic tools drop in pressure, and assembly crews suffer physical strain under short shift rotations. Luyuan provides "Boltless & Semi-Knocked-Down" designs that decrease field installation times by 35%. Complete installation drawings, structural video briefings, and localized engineering agency support streamline assembly.
By producing from Guangdong, China's industrial center, Luyuan leverages direct procurement alliances with top steel mills (such as Baosteel and Ansteel). This integration ensures we acquire certified structural plate grades at competitive price ranges. Additionally, the region’s deep port facilities in Shenzhen and Guangzhou enable direct ocean logistics to the Americas, Europe, Australia, and the Middle East, reducing cargo transit costs and shortening shipment timelines.
Every cold storage facility has unique SKU profiles, speed requirements, and temperature criteria. Discover our custom-configured styles.
Best for high-density, low-SKU operations such as bulk meat, frozen seafood, or single-product beverage stores. Pallets are stored on support rails in depth lanes, allowing forklifts to drive inside the bays. This design maximizes storage volume by eliminating aisles but utilizes a LIFO (Last-In, First-Out) rotation method.
Semi-automated solution featuring high-density storage tunnels and a robotic shuttle cart. The shuttle picks up, transports, and places pallets within the rack channels. It operates safely in sub-zero environments, minimizes forklift travel distances, decreases frame damage risks, and supports both FIFO and LIFO options.
Standard racks mounted on motorized base rails that roll along floor guides. Individual aisles open up via remote command. This configuration matches high-density pallet capacities with 100% selective accessibility, making it ideal for pharmaceutical facilities and multi-SKU food distribution centers.
