Engineered for maximum thermal efficiency and structural durability.
Technological trends and market shifts for 2024 and beyond.
Modern sandwich PU panels now target thermal conductivity as low as 0.019 W/(m·k). In the context of global rising energy costs, "Thermal Gain Prevention" is no longer an option but a financial necessity for cold storage operators.
The transition from PUR to PIR (Polyisocyanurate) represents the industry's response to stringent safety regulations. Our PIR panels achieve Class B1 fire ratings, ensuring structural integrity even under high-temperature stress.
Decarbonization is driving the use of Pentane-blown foams. We are shifting toward eco-friendly manufacturing processes that reduce Global Warming Potential (GWP) to meet international environmental compliance.
As a leading High-Quality Sandwich PU Manufacturer, we recognize that a cold room is a complex ecosystem. Our "Macro Solution" approach integrates PIR/PU sandwich panels with precision-engineered condensing units and evaporators. This holistic design ensures that thermal bridges are eliminated, and the "Air-Cooling" cycle is optimized for the specific biological requirements of the stored goods—whether it's delicate pharmaceuticals or high-volume agriculture products.
Our 20+ years of expertise allow us to provide localized support, ensuring that our equipment operates reliably in varied climates, from the humid tropics to the arid Middle East, always adhering to local electricity and safety standards.

How we serve international exporters and large-scale industrial buyers.
We provide full documentation and compliance support for CE certification, ISO quality standards, and regional building codes. This reduces the friction for international exporters and ensures smooth customs clearance.
Our technical roadmap includes the integration of IoT sensors within sandwich panels to monitor moisture ingress and R-value degradation in real-time, providing predictive maintenance data to operators.
For global procurement, we utilize modular packaging systems that maximize container space utilization (up to 25% increase), significantly reducing the shipping cost per square meter of paneling.
Expert answers to your technical and commercial queries.
PIR (Polyisocyanurate) is an evolution of PU (Polyurethane). While both offer excellent insulation, PIR has a higher ratio of isocyanate, which creates a more stable molecular structure, resulting in significantly better fire resistance and slightly higher thermal performance.
Our cam-lock panels feature integrated eccentric locking mechanisms. This allows for rapid on-site assembly without the need for complex structural framing, ensuring a seamless, airtight joint that prevents thermal leakage.
Yes. Beyond manufacturing panels, we provide a complete engineering package, including load calculations, equipment selection (evaporators/condensers), and schematic designs for cold storage projects ranging from 100 to 50,000 cubic meters.
With proper installation and maintenance, our high-density PU panels are designed to last over 25 years. The color-coated steel skins are treated with anti-corrosive coatings to withstand harsh industrial environments.
Our dedicated 10-person QC team conducts rigorous testing on every batch, including density checks, pull-strength tests, and thermal conductivity verification. All export orders undergo a final inspection before container loading.
