In modern industrial refrigeration and cold chain infrastructure, the selection of thermal insulation envelopes plays a decisive role in operational efficiency, carbon footprint mitigation, and temperature preservation stability. Among various structural components, the 50mm Cold Room Panel stands out as a highly specialized architectural solution designed to satisfy intermediate thermal requirements. Whether utilizing Polyurethane (PU) or Polyisocyanurate (PIR) cores, these panels deliver optimized mechanical strength and thermal resistance suitable for high-performance cooling applications.
As a leading 50mm cold room panels manufacturer, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. integrates 20+ years of engineering experience with cutting-edge automated production lines. Our mission is to supply highly precise, thermally optimized, and structurally sound insulation panels that cater to modern global commercial enterprises, logistics hubs, and pharmaceutical installations.
Maximizes energy retention in intermediate temperature zones (+0°C to +15°C), dramatically lowering daily operating costs for commercial refrigeration structures.
Equipped with advanced tongue-and-groove or cam-lock joints, guaranteeing rapid airtight installation and robust load-bearing capabilities.
Available in both premium Polyurethane (PU) and fire-retardant Polyisocyanurate (PIR) cores, conforming to strict fire safety and regulatory standards.
The global refrigeration industry has experienced a tectonic shift towards energy-sustainable and modular building envelopes. 50mm cold room panels are highly sought-after in localized cold chains, urban distribution centers, and processing cleanrooms. Because of their lightweight profile yet high structural rigidity, these panels serve as the standard choice for partitions, false ceilings, and intermediate-temperature walk-in coolers.
Specifically, in urban areas where land prices are high, micro-fulfillment centers and supermarket storage facilities rely heavily on 50mm panels to maximize space without sacrificing essential insulation. According to global cold storage building standards, while deep sub-zero environments (-20°C to -40°C) require thicknesses upward of 100mm to 200mm, the 50mm thickness is the thermodynamic sweet spot for preparation rooms, food packing rooms, and laboratories where temperatures fluctuate between +2°C and +10°C.
Moreover, modern cold storage operations must comply with rigorous international energy audits. Utilizing panels with poor foam density or imperfect joints leads to chronic thermal bridging, forcing refrigeration units to work harder. Our 50mm sandwich panels utilize high-density polyurethane formulation (averaging 40-42 kg/m³) to ensure a consistent thermal barrier, satisfying global initiatives for carbon neutrality.
Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. is a professional factory and enterprise focusing on premium insulation panels and integrated refrigeration equipment. Beyond pure product manufacturing, we pride ourselves on delivering comprehensive project lifecycle services—including custom engineering design, on-site construction, expert installation, and dedicated after-sales support.
We integrate high-quality products, one-stop project solutions, engineering-advanced services, and international trade capabilities to provide global buyers with exceptional value. Our fields of expertise span cold storage for agricultural products (fruits, vegetables, meat processing), large-scale supermarkets, logistics hubs, hotels, catering, medical repositories, and high-tech cleanrooms.
Operating a modernized production facility of 60,000 square meters featuring 4 standardized workshops, our manufacturing capabilities are supported by about 180 skilled technicians and an elite 10-member Quality Control (QC) team. This allows us to guarantee structural precision and aesthetic quality across every single batch. Our advanced production lines and continuous foaming techniques enable high-capacity manufacturing of PIR and PU sandwich panels, specialized cold room doors, water defrosting evaporators, and complex condensing units.
Our founder initiated operations focusing on standard refrigeration equipment marketing, installation, and field service support.
Completed construction of our first manufacturing facility in Shaanxi, producing our first cam-lock insulation sandwich panels.
The second manufacturing facility in LanZhou was successfully completed, positioning our brand to cover the vast north-west China cold storage markets.
In response to rapid business expansion and emerging international projects, Shaanxi factory relocated to a larger, modernized 120-acre facility housing 8 advanced workshops.
Deployed our first continuous, high-efficiency automatic split-joint production line, transitioning our factory into a high-capacity smart facility.
Our second automated, continuous production line went online. This increased our overall productivity, optimized raw material yield, and enhanced foam density consistency.
Committed fully to environmental sustainability. Relocated processes toward green manufacturing, utilizing eco-friendly foaming agents and reducing overall waste.

The manufacturing process ensures that the foam is injected into the sandwich mold under high pressure. The chemical reaction creates millions of micro-cells that effectively trap air and restrict heat transfer. This high-density core prevents sagging over time and resists moisture absorption, which is critical to preventing mold growth and maintains structural integrity throughout the system's operational lifespan.
For international buyers and refrigeration distributors, sourcing from China-based factories presents immense cost-to-performance advantages. Here is how Shaanxi YuanShengHeTong delivers these advantages:
We source steel coils and chemical prep-materials in high volume directly from major domestic steel mills. This bypasses intermediary markups and passes savings directly to our buyers.
Equipped with dual fully automated high-speed sandwich panel laminator lines, we easily handle large volume orders (over 5,000 sqm) within aggressive project timelines.
Our 10-person dedicated QC team performs peel-strength testing, density measurement, and dimensional inspection on every shift. This guarantees zero defects upon export.
Our commitment to manufacturing excellence is verified by international certification bodies. We follow ISO 9001 and CE protocols to meet the import requirements of European, American, and Asian markets.
To help engineers and procurement directors make informed decisions, we have compiled answers to common technical queries based on industry standards.
