In the modern industrial landscape, the choice of roofing material is no longer just about shelter; it is a critical decision affecting thermal efficiency, structural longevity, and carbon footprint. Sandwich metal roof panels, characterized by a dual-layer metal skin and a high-performance insulating core (typically PIR, PUR, or Rockwool), have emerged as the gold standard for global industrial facilities.
As a leading OEM Sandwich Metal Roof Panels Manufacturer, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. understands the semantic shift in construction. Today’s procurement managers are not just looking for "panels"—they are seeking integrated thermal envelopes that reduce HVAC energy consumption by up to 40% and provide superior fire resistance in compliance with international standards like FM Global and CE.
Shaanxi YuanShengHeTong Refrigeration Co., Ltd. is a professional factory and enterprise focusing on insulation panels and refrigeration equipment. Since our inception in 1996, we have integrated high-quality product manufacture with one-stop project solutions, including design, construction, installation, and after-sales service.
With over 20 years of experience, we specialize in the refrigeration needs of fruits, vegetables, and the food industry, as well as large-scale logistics, medical facilities, and high-end hospitality. Our commitment to E-E-A-T principles ensures that every panel leaving our 60,000 square meter facility meets the rigorous demands of the global market.
PIR represents the premium tier of insulation. Its enhanced chemical structure offers superior fire resistance and lower smoke emission. It is the preferred choice for high-risk industrial environments and insurance-mandated projects.
Highly cost-effective with exceptional thermal conductivity (λ ≈ 0.022 W/m·K). Ideal for cold storage and controlled atmosphere environments where temperature stability is the primary concern.
Our OEM capabilities allow for variations in metal skin thickness (0.4mm - 0.8mm), coating types (PE, PVDF, HDP), and core densities to meet specific structural and climate requirements.
The global shift toward Chinese manufacturing in the sandwich panel sector is driven by more than just cost. It is about Supply Chain Integration and Agile Production.
Located in the heart of China's industrial hubs, we access raw steel and chemical components with zero lead-time lag, passing those savings directly to our global partners.
Our engineering team can take a blueprint and produce custom panel profiles within days, a feat that takes weeks for many Western manufacturers.
With 120 acres of production area and multiple automatic lines, we handle "mega-project" orders of 50,000+ square meters without compromising on local delivery schedules.
Humidity-resistant PVDF coatings on our sandwich panels prevent corrosion in tropical climates, ensuring food safety for regional distribution hubs.
Utilizing PIR cores with high acoustic damping properties to protect sensitive equipment and satisfy urban noise regulations.
Cam-lock PU panels provide the airtight seal required for energy-intensive pharmaceutical storage, meeting strict FDA-compliant temperature zones.
Founder started in refrigeration equipment marketing and installation.
First factory completed in Shaanxi; first cam-lock sandwich panels produced.
Relocation to 120-acre facility with 8 advanced workshops.
Implementation of the first automatic split-joint production line.
Transitioning into a fully eco-friendly factory for sustainable manufacturing.
For international enterprises, sourcing OEM sandwich panels involves complex logistics and compliance. Our export division specializes in:
We use specialized racking systems to prevent panel deformation during sea freight, ensuring panels up to 12 meters arrive in pristine condition.
Full support for CE, ISO, and regional fire safety certifications to ensure smooth customs clearance and building permit approval.
With high-quality PVDF coating and proper installation, our panels are designed for a service life of 25-40 years, depending on the environmental conditions.
Yes, we provide detailed technical drawings, installation manuals, and can arrange for remote video guidance or on-site engineering supervisors for large-scale projects.
The R-value depends on thickness. For example, a 100mm PUR panel typically provides an R-value of approximately 30-34 (ft²·°F·h/BTU), making it extremely efficient.
Absolutely. We offer food-grade stainless steel or specialized anti-bacterial coatings that meet international health and safety standards for the food industry.
PIR panels do not melt or drip when exposed to fire; they form a carbonaceous "char" layer that protects the inner core and delays flame spread.
While we can produce panels of any length, shipping containers typically limit length to 11.8 meters (for 40ft HQ containers).
