The certifications held by a sandwich panel manufacturer serve as a key indicator of product quality, regulatory compliance, and corporate capability. Requirements vary depending on the application scenario, but the essential certifications generally fall into three categories: foundational management system certifications, product-specific certifications, and international export certifications.   Foundational management system certifications form the basis of compliant operations. Key certifications include ISO 9001 (Quality Management System), ISO 14001 (Environmental Management System), and ISO 45001 (Occupational Health and Safety Management System). These three certifications cover the control of the entire production process—ensuring consistent product quality and environmentally safe production—and serve as a basic threshold for domestic project procurement; without them, it is difficult for a company to guarantee product consistency.   Product-specific certifications are crucial for ensuring sandwich panels meet project requirements. Fire safety certification is paramount; products must comply with the GB 8624 standard and possess corresponding fire-rating test reports. For Class A non-combustible panels, additional fire-resistance limit test reports are required—a mandatory stipulation for commercial projects and industrial facilities. Next is Green Building Material certification; certified products receive priority in government-funded engineering works and green building projects, aligning with current policies on building energy efficiency. Additionally, for specialized environments such as clean rooms and cold storage facilities, specific certifications regarding cleanliness levels and thermal insulation performance are required.   International export certifications are essential for expanding into overseas markets. Exports to the EU require CE certification based on the EN 14509 standard, covering comprehensive requirements for product performance and safety. Exports to the US and similar regions may benefit from FM certification to enhance product recognition, while exports to Australia require AS1530 and Code Mark certifications. Certain regions also mandate compliance with local standards—such as Russia's GOST certification—to ensure smooth customs clearance and adherence to local engineering requirements.   In summary, a high-quality sandwich panel manufacturer must hold foundational system certifications, product-specific certifications, and relevant international certifications. When procuring materials, it is essential to verify the authenticity and validity of these certificates to prevent project acceptance issues caused by incomplete qualifications.  

The Sandwich panels are widely used in food processing factories due to their excellent thermal insulation, good moisture and water resistance, corrosion resistance, and excellent fire resistance.     1. Excellent thermal insulation performance. Generally, the thermal conductivity of PU/PIR sandwich panels is between 0.020 and 0.024 [W/(m·K)], providing good thermal insulation and effectively controlling indoor and outdoor temperatures to ensure food freshness.   2. Seamless splicing during assembly ensures good sealing, reducing the risk of bacteria and mold growth and enabling dust-free workshops.   3. The core material used in sandwich panels has a high closed-cell rate, is non-absorbent, and offers excellent waterproof and moisture-proof performance, ensuring food freshness.   4. The color-coated steel plates used in sandwich panels have high structural strength, strong load-bearing capacity, and good corrosion resistance.   5. Sandwich panels generally have a fire rating of B1 (PIR sandwich panels) or A (rock wool sandwich panels), offering excellent fire resistance and making them more suitable for high-temperature food processing workshops;   6. Sandwich panels are produced in modular form, requiring only on-site installation and splicing, resulting in simple construction, short construction period, less dust, and high cost-effectiveness.
