The global metal sandwich panel market has entered a phase of high-precision engineering. As the world shifts toward Net Zero Energy (NZE) buildings, the demand for high-performance insulation materials—specifically PIR (Polyisocyanurate) and PUR (Polyurethane) core panels—has skyrocketed. China, as the world's leading manufacturing hub, now accounts for over 40% of the global export volume, shifting from "mass production" to "high-value innovation."
Current industrial trends emphasize the transition from traditional mineral wool to synthetic foam cores, which offer a significantly higher R-value per inch. This is critical for the booming global cold chain logistics market, which is projected to grow at a CAGR of 15% through 2030, driven by pharmaceutical needs (vaccine storage) and the globalized fresh food trade.
According to recent industry audits, the "China Metal Sandwich Panel" sector has seen a 25% increase in R&D investment focused on fire safety (FM Approved & ASTM standards). This ensures that modern China-made panels are not only affordable but meet the strictest insurance requirements in Europe and North America.
Shaanxi YuanShengHeTong Refrigeration Co., Ltd. is a professional factory and enterprise focusing on insulation panels and refrigeration equipment. Besides product manufacture, we also provide services like project design, construction, installation, as well as after-sales service.
We integrate "high quality products, one-stop project solution, engineering advanced services, and international trade" to provide customers with excellent products and satisfied services. Our involved professional fields include refrigeration of fruits, vegetables, food industry; also refrigeration of large supermarkets, restaurants, hotels, medical and logistics companies etc.
Our business in refrigeration fields started in 1996, with more than 20 years experience in refrigeration industry, we are confident in our professionality. And our factory is specializing in refrigeration manufacturing and technology.
Transitioning from PUR to PIR (Polyisocyanurate) has been the major leap in the last decade. Our roadmap includes Ultra-Low Lambda panels reaching 0.018 W/m·K by 2025 using nano-porous structure enhancements.
Future metal sandwich panels will feature "Self-Extinguishing" properties exceeding Grade B1. We are integrating ceramic-fiber layers within the core to provide 2-hour fire resistance ratings (FRR).
Our 4th generation production lines utilize AI vision systems to detect core voids and surface imperfections in real-time, ensuring 99.9% consistency in insulation density.
With about 180 workers and 10 QC team, the quality and efficiency are guaranteed of our products. Now, the factory has an existing production site of 60,000 square meters, 4 standardized workshops, high quality and efficient production equipment, as well as advanced production lines and techniques. Our factory mainly produces PIR(Polyisocyanurate) and PU(Polyurethane) sandwich panels, cold storage doors, air coolers, condensers, condensing units, compressor units etc.
Stringent ±0.5°C temperature control using PIR panels for GSP/GMP certified medical warehouses. Anti-bacterial steel coatings are utilized for hygienic safety.
Large-scale CA (Controlled Atmosphere) storage for fruit and vegetable preservation. Our panels provide the airtightness required to manage O2 and CO2 levels.
Dust-free environments for semiconductor and electronics manufacturing. Features seamless joint technology to prevent particulate accumulation.
PUR (Polyurethane) is a standard high-efficiency insulation. PIR (Polyisocyanurate) is an advancement of PUR with better fire resistance (Grade B1) and higher thermal stability. PIR panels char rather than melt when exposed to flame, providing critical time for fire containment.
For high-corrosion environments, we utilize specialized metal skins like Stainless Steel 304/316 or PVDF (Polyvinylidene Fluoride) coated galvanized steel. These coatings offer superior resistance to salt spray and UV degradation, extending the lifespan to 20+ years.
Yes. Our roof sandwich panels are designed with deep-ribbed profiles and high-density cores (40-42kg/m³) to provide high load-bearing capacity. The interlocking joint design ensures water-tightness even under significant snow loads.
Modern panels contribute significantly to LEED certification. They reduce building energy consumption by up to 50% compared to traditional masonry. Furthermore, the steel and foam components are increasingly recyclable in a circular economy model.
