Premium-grade structural steel configurations, tailored specifically to withstand heavy static loads under extreme refrigeration cycling.
Operating a cold warehouse or deep-freeze facility demands strict adherence to metallurgical engineering guidelines. Standard carbon steel undergoes a fundamental transformation called the Ductile-to-Brittle Transition Temperature (DBTT) when exposed to environments below freezing, specifically between -18°C and -40°C. Under these conditions, the shock absorbency of basic steel structural frames drops significantly, making standard industrial racking highly susceptible to sudden stress failure from minor forklift impacts.
As leading CE certified cold storage rack manufacturers, Shenzhen Yuanzhang Trading Co., Ltd. addresses this issue by utilizing specialized high-yield structural alloys. We manufacture our racks using Q355D and Q355E steel grades. These materials undergo Charpy V-notch impact testing at -20°C and -40°C, ensuring the metal preserves its structural flexibility, strength, and impact resistance in extreme low temperatures.
Compliance with European standards is not just a regulatory checkbox; it is a fundamental safety requirement. Our heavy-duty racking systems are engineered in strict compliance with the structural calculations outlined in EN 15512 (Steel static storage systems – Adjustable pallet racking systems – Principles for structural design).
Rigorous structural calculations that analyze buckling configurations under load patterns, factoring in low-temperature material behavior.
Automated robotic pulse-welding setups minimize thermal stress and micro-fissures in high-load joint assemblies.
Ensures precision alignment during installation, which is critical for the safe operation of high-bay Automated Storage and Retrieval Systems (AS/RS).

Established in 2015, Shenzhen Yuanzhang Trading Co., Ltd. is a leading manufacturer and exporter specializing in heavy-duty warehouse racking and customized industrial storage systems. Operating out of a state-of-the-art 35,000 m² production facility, we bring 12 years of deep industry expertise and 8 years of dedicated international trade experience to global logistics and commercial storage projects.
Driven by technical excellence, our operations are backed by a robust research and development center staffed with 25 expert R&D engineers. Demonstrating our strong commitment to innovation, we launched over 150 new storage solutions last year alone. We offer fully versatile OEM/ODM custom options, including specialized dimensions, weight capacity adjustments, surface coatings, and modular structural designs to meet diverse client requirements.
Quality and reliability form the foundation of our business. We enforce strict multi-stage quality control—utilizing advanced automated ultrasonic testing, raw material stress analysis, and load-bearing fatigue assessments executed by a dedicated team of 45 QA/QC inspectors. With an annual export revenue of $28 million USD and a resilient global supply chain network of over 800 strategic raw material and component partners, we maintain steady delivery timelines worldwide.
Humidity is a constant challenge in cold storage logistics. Whenever cold storage doors open, warm outside air meets cold interior temperatures, creating condensation on cold metal surfaces. If the rack surfaces are not properly treated, this moisture can rapidly lead to localized oxidation and structural compromise.
Our CE-compliant manufacturing process features advanced surface treatments, using an epoxy-polyester thermosetting powder coating. The steel undergoes a multi-stage pre-treatment wash, followed by iron-phosphate conversion, and is then electrostatic-coated and cured under high heat. This creates a dense, non-porous barrier that prevents moisture penetration. For high-humidity cold rooms or meat storage facilities, we offer Hot-Dip Galvanizing (HDG) in accordance with ISO 1461 standards, providing long-lasting corrosion protection that resists flaking and scratching under heavy industrial use.
Shenzhen Yuanzhang Trading Co., Ltd. serves clients in North America, Western Europe, Southeast Asia, and the Middle East. When designing your cold storage racking, our engineering team uses advanced structural analysis to factor in regional geological risks:
We engineer structural racking to comply with local seismic building codes, incorporating larger baseplates and high-strength anchoring systems to absorb seismic energy.
Engineered dual-post upright designs and heavy-duty frame bracing provide high impact resistance at key points where forklift collisions are most likely to occur.
From raw engineering drawings to on-site assembly guidance, we provide clear documentation to ensure local installation crews set up the system safely and efficiently.
