The global demand for Panel Sandwich Metálicos (metallic sandwich panels) has witnessed an unprecedented surge, driven by the rapid expansion of the cold chain logistics, pharmaceutical storage, and modular construction sectors. In the post-pandemic era, food security and medicine temperature stability have become national priorities, positioning high-performance insulation panels as critical infrastructure components.
The global sandwich panel market is projected to reach $12.5 billion by 2028, with a CAGR of 6.5%. China remains the dominant exporter due to integrated supply chains.
Latin America and Southeast Asia are the fastest-growing regions, moving from traditional building methods to metallic modular insulation systems.
Stricter fire safety regulations (FM Global, CE, ASTM) are pushing manufacturers to shift from standard EPS/PU to high-performance PIR and Mineral Wool cores.
As a leading China manufacturer, Shaanxi YuanShengHeTong Refrigeration Co., Ltd. has been at the forefront of this evolution since 1996. By integrating PIR (Polyisocyanurate) technology with precision-engineered metallic facings, we provide the "information gain" that procurement officers need: higher R-values, lower thermal bridging, and superior structural integrity.
Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. is not just a factory; we are an integrated engineering powerhouse. Our 60,000 square meter facility houses four standardized workshops equipped with the latest automatic split-joint production lines.
Our workforce of 180 professionals, including a dedicated 10-person QC team, ensures that every square meter of Panel Sandwich Metálicos meets rigorous international standards. Our expertise spans fruit and vegetable cold storage, large-scale supermarket refrigeration, medical logistics, and industrial hotel facilities.
While Polyurethane (PU) has been the standard, PIR (Polyisocyanurate) is the future. It offers superior fire resistance (B1 class) and enhanced thermal performance, reducing energy costs by up to 20% compared to traditional materials.
Automation is no longer optional. Our 2020 investment in a second advanced automatic production line ensures millimeter-precision in panel interlocking, eliminating the "thermal bridges" that plague manual installations.
Moving towards 2024, we are focusing on eco-friendly, food-grade coatings that are resistant to corrosion and antimicrobial, essential for high-hygiene pharmaceutical environments.
Customized 100mm-150mm PU panels for fruit and vegetable preservation, ensuring "Farm to Table" freshness with minimal humidity loss.
High-spec PIR panels with seamless cam-lock joints designed for GSP-compliant medicine storage (-20°C to +8°C).
Utilizing metallic sandwich panels for rapid assembly of cleanrooms, temporary offices, and high-tech manufacturing labs.
While both use polyurethane chemicals, PIR (Polyisocyanurate) is formulated with a higher ratio of isocyanate, resulting in significantly better fire resistance and slightly better thermal insulation than standard PU.
When specified with PVDF or high-durable polyester (HDP) coatings, our panels can resist salt-spray corrosion for over 20 years, making them ideal for port-side cold storage.
Yes, our PIR panels are designed to meet B1/B2 fire ratings according to GB8624 standards, which align with most international building codes for industrial warehouses.
Absolutely. Shaanxi YuanShengHeTong provides a "One-Stop Solution," including panels, doors, compressors, and evaporators, along with full installation engineering services.
