Explore our catalog of certified industrial handling carts, heavy-duty shelving units, and modular logistics solutions engineered for harsh operating environments.
Established in 2015, Ningbo Xinyi Metal Products Co., Ltd. is a leading manufacturer specializing in heavy-duty industrial storage racks, pallet racking systems, and customized warehouse material handling solutions. Spanning a state-of-the-art production facility of 38,000 square meters, we deliver high-performance racking products to global logistical hubs, distributors, and enterprise facilities.
With 11 years of deep industry expertise and 8 years of dedicated international trade experience, our annual export revenue has reached over $28 million USD. Our footprint spans major global markets, including North America, Western Europe, Southeast Asia, and the Middle East, serving diverse client segments such as third-party logistics (3PL) providers, e-commerce fulfillment centers, industrial distributors, and large-scale retail chains.
Quality and structural integrity are at the core of our manufacturing processes. Supported by a rigorous Quality Assurance team of 45 certified inspection professionals, we enforce strict full-process quality control.
Our quality testing methods integrate ultrasonic weld inspection, raw material tensile testing, load-capacity deflection testing, and salt-spray corrosion resistance evaluation to guarantee long-term durability and safety compliance in extreme cold temperatures.

The global cold chain logistics market is undergoing exponential growth driven by the expansion of quick-commerce grocery delivery, pharmaceutical storage (including vaccines and biologics), and food security regulations. Managing cold storage facilities presents unique engineering challenges. Sub-zero temperatures (-18°C to -40°C) dramatically affect the physical properties of structural steel, increasing brittle-fracture risks. At the same time, the high energy cost of maintaining low temperatures dictates the absolute need for maximum spatial density. Selecting the correct OEM/ODM partner is a crucial capital expenditure decision for international procurement directors.
Standard structural steels (like general carbon steels) exhibit a dramatic drop in impact toughness at temperatures below freezing point. This is known as the ductile-to-brittle transition temperature (DBTT). If structural racks are manufactured using generic steel grades, under concentrated static and dynamic pallet loads, they are highly prone to sudden, catastrophic failure without warning.
As an expert OEM/ODM exporter, Ningbo Xinyi Metal Products Co., Ltd. sources high-grade structural alloys, such as Q355D or Q355E, specifically designed and certified for impact toughness at -20°C and -40°C respectively. These steel formulations incorporate micro-alloying elements like vanadium, niobium, and titanium, which refine the grain structure, providing high yield strength (up to 355 MPa) and maintaining high Charpy V-notch impact values under deep freezing conditions.
Cold storage environments are highly susceptible to moisture condensation during defrosting cycles or when ambient air enters the facility. Moisture, combined with high-density steel layout, creates a highly corrosive environment. We provide two primary OEM surface treatment routes to combat rust:
| Technology / Spec | Hot-Dip Galvanized (HDG) | Epoxy Powder Coated | Stainless Steel (304 / 316) |
|---|---|---|---|
| Operating Temp Range | -50°C to +60°C | -30°C to +50°C | -100°C to +400°C |
| Corrosion Resistance | Excellent (Self-healing zinc layer) | High (Barrier protection) | Maximum (Oxide passivation layer) |
| Abrasion Resistance | Outstanding | Moderate to High | High |
| Ideal Application | Extreme Humidity & Freeze cycles | Standard dry sub-zero warehousing | Clean-room / Pharmaceutical zones |
| Relative Cost Factor | Medium - High | Cost-Effective | Premium High-End |
Because building cold storage footprint space is extremely expensive, optimizing the layout density is key to reducing utility costs. Standard selective pallet racking is often replaced with high-density configurations:
Under deep freeze conditions, static loads from fully-laden pallets present high risk if the warehouse is located in a seismically active zone. Our engineering division utilizes Finite Element Analysis (FEA) software (ANSYS and RFEM) to simulate seismic accelerations, ensuring our uprights, horizontal beams, and diagonal bracing configurations comply with international engineering codes including RMI (USA) and EN 15512 (Europe).
