Unlike standard PUR, our 2-hour fire-rated sandwich panels utilize a high-index Polyisocyanurate (PIR) core. This material undergoes a chemical reaction during fire exposure that creates a protective "charring" layer. This layer effectively blocks oxygen and heat penetration, preserving the structural integrity of the wall for a full 120 minutes—a critical metric for life safety and asset protection.
Our OEM manufacturing process ensures that the bonding between the 0.5mm - 0.8mm steel skins and the PIR core remains stable under extreme thermal stress. This prevents delamination during a fire event, ensuring the panels continue to act as a barrier against flames and smoke, satisfying the most stringent global building codes.
We provide comprehensive certification support including CE and ISO 9001. Our panels are designed to meet or exceed international fire safety standards such as ASTM E84 Class A and EN 13501-1. This ensures that global enterprises can source from us with full confidence in local legal compliance.
Our Shaanxi-based factory features the latest automatic split-joint production lines introduced in 2018 and 2020. This automation minimizes human error and ensures that every square meter of our 2-hour fire-rated panel maintains a consistent density and thermal k-value.
By leveraging the massive industrial ecosystem in Northwest China, we offer OEM pricing that is 15-30% more competitive than European counterparts without compromising on the quality of raw materials like high-grade galvanized steel and BASF chemical components.
Located in the heart of the "Belt and Road" hub, our logistics network provides seamless multimodal transport solutions—rail to Europe and sea to Southeast Asia, Africa, and the Americas—ensuring timely project delivery.
Tailored solutions for diverse global environments
In regions with strict medical regulations, our panels provide the necessary fire containment and antimicrobial surfaces required for high-stakes laboratory and drug storage environments.
Modern data centers generate immense heat. Our 2-hour fire rating provides the essential safety window needed for fire suppression systems to activate and protect billion-dollar hardware assets.
For large-scale frozen food distribution centers, the combination of superior insulation and fire safety reduces insurance premiums and satisfies local fire marshal requirements.
As industrial spaces move vertical, the 2-hour fire rating becomes a legal mandate to prevent floor-to-floor fire spread in urban manufacturing hubs.
Founded in 1996, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. has evolved from a local refrigeration equipment marketer into a global powerhouse in insulation panel manufacturing. With over 28 years of industry experience, we are not just a manufacturer; we are a total project solution provider.
Our 60,000-square-meter facility houses 4 standardized workshops equipped with industry-leading technology. We specialize in PIR/PU sandwich panels, cold storage doors, and comprehensive refrigeration units. Our E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is backed by 180 skilled workers and a dedicated 10-person Quality Control team.
As of 2023, our factory is moving toward eco-friendly production. We are incorporating recycled materials and low-GWP (Global Warming Potential) blowing agents to help clients achieve LEED and BREEAM certifications.
The industry is shifting toward "Smart Panels" embedded with thermal sensors. We are currently researching ways to integrate real-time temperature monitoring within the sandwich panel core for early fire detection.
The rise of Prefabricated Industrial Buildings (PEB) demands panels that are fire-rated and easy to install. Our cam-lock and tongue-and-groove systems are evolving to provide even faster onsite assembly times.
