In the era of global carbon neutrality and heightened energy efficiency requirements, Polyisocyanurate (PIR) sandwich panels have emerged as the gold standard for industrial thermal insulation. As leading China PIR panel sandwich manufacturers, we recognize that the shift from traditional materials to PIR isn't just a trend—it's a technical necessity for modern cold storage, logistics hubs, and green building construction.
PIR panels offer superior fire resistance (typically B1 grade), exceptional R-values, and structural integrity that PUR (Polyurethane) cannot match. Our manufacturing process integrates advanced chemical formulations with precision engineering to ensure that every panel exported from our facility meets international standards such as CE and FM Global requirements. This deep dive explores why Chinese manufacturing excellence is reshaping the global supply chain for high-performance insulation.
Our facility features the latest automatic split-joint production lines (installed in 2018 and 2020), ensuring uniform foam density and superior surface flatness across large-scale orders.
By leveraging China's robust chemical supply chain, we produce PIR cores with optimized cell structures that provide lower thermal conductivity (λ ≤ 0.022 W/m·K).
Scale allows us to offer premium PIR solutions at prices that outperform European and American alternatives without compromising on CE-certified quality.
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.
As e-commerce and fresh food delivery grow globally, the demand for "Last Mile" cold storage and large-scale distribution centers has skyrocketed. Our PIR panels provide the thermal stability needed for these high-frequency operations.
Precision temperature control is non-negotiable for vaccines and medicines. Our airtight cam-lock PU/PIR systems ensure zero thermal leakage, meeting strict GSP/GMP requirements.
Green building certifications (LEED/BREEAM) prioritize materials with high insulation values. PIR's long-term thermal performance makes it a primary choice for carbon-conscious developers.
What international buyers look for when choosing a China PIR panel exporter.
Ensuring CE, ISO, and fire rating certifications (B1/B2) are authentic and up to date for international customs and safety audits.
Offering thickness ranges from 50mm to 200mm and various surface coatings (SUS304, Color Steel, PVC) for corrosive environments.
Moving beyond selling panels to providing project design, refrigeration unit matching, and installation guidance.
While both are polyurethane-based, PIR (Polyisocyanurate) has a higher ratio of isocyanate, resulting in a more stable isocyanurate ring structure. This gives PIR superior fire resistance (Class B1) and better thermal stability compared to standard PUR (Class B2).
China has the world's most complete industrial chain for sandwich panels. Factories like YuanShengHeTong offer the latest continuous production technology, competitive pricing due to raw material access, and the capacity to handle massive international projects with short lead times.
We employ a 10-person QC team that monitors every stage—from chemical mixing and steel coil tensioning to foam adhesion and final packaging. Our 60,000㎡ facility is optimized for quality consistency across 4 standardized workshops.
Yes. We offer stainless steel (SUS304) or food-safe coated steel surfaces that are easy to clean, resistant to bacteria growth, and meet international hygiene standards for food processing and pharmaceutical storage.
