For cold chain warehousing and cold storage operators, poor selection of insulation materials leads to endless troubles: fire resistance fails inspections, rapid heat loss drives up electricity costs, and panels degrade or deform in just two years due to low-temperature sensitivity... Don’t worry—Yanghu Refrigeration’s A1-grade polyurethane-edged rock wool sandwich panels are specifically designed to tackle these pain points, offering three core advantages that ensure worry-free selection and hassle-free use.

1. Dual Guarantee of Safety and Energy Efficiency, Reducing Operating Costs

One of the core advantages of this sandwich panel is its dual focus on "safety" and "energy efficiency." It utilizes A1-grade non-combustible rock wool core material, which undergoes rigorous testing and certification by national authorities for each batch. Even in high-temperature environments, it not only resists combustion but also effectively blocks fire spread, enabling cold storage facilities to easily pass fire safety compliance inspections and eliminate potential safety hazards.

Meanwhile, its thermal conductivity is as low as ≤0.040 W/(m・K), equivalent to "insulating armor" for the cold storage, effectively locking in internal coldness and reducing frequent compressor cycling.

2. Strong freeze resistance and corrosion resistance, durable for over a decade with minimal maintenance

The cold chain environment is low-temperature and humid, making ordinary panels prone to freezing cracks and rust. However, Yanghu Refrigeration's sandwich panel features a high-galvanized color steel plate for the outer layer, with a zinc coating thickness of ≥120g/m², offering 30% greater corrosion resistance than standard panels. Even in prolonged humid conditions, it resists rust and deformation effectively.

More importantly, it can easily withstand ultra-low temperatures of -30°C. Whether it's a deep freezer storing frozen meat or a pharmaceutical cold storage for vaccines, the panels maintain a stable structure without cracking or loosening.

3. Tailored services are exceptionally considerate, also suitable for small and medium-sized enterprises

Considering the varying sizes and shapes of cold storage required by different users, Yanghu Refrigeration offers customized services. Utilizing CNC cutting technology, the error margin is precisely controlled within ±0.5mm, ensuring perfect fit even for the unique corners of irregularly shaped cold storage. This approach enhances installation efficiency by 50% compared to traditional paneling.

Moreover, the recycling rate of production byproducts reaches 95%, effectively reducing raw material costs and making the product's cost-performance ratio 15% higher than that of similar products. Whether it's a new enterprise building a large cold storage facility of thousands of square meters or an individual operator renovating a small cold storage of just a few dozen square meters, both can easily afford it without worrying about costs.

Whether you're building a new cold storage or renovating an existing one, Yanghu Refrigeration's Class A polyurethane-edged rock wool sandwich panels are a reliable choice. Call now at 0519-88781801 to secure your discount and make your cold chain operations more hassle-free and cost-effective!
