Product details
The high-performance spray painted sandwich panel (HPGI) is specially designed for cleanroom wall and ceiling systems, particularly for pharmaceutical, biotechnology, and healthcare facilities. The panel is manufactured using a high-quality steel substrate with an advanced spray painting process, ensuring superior surface performance compared to conventional pre-painted steel panels.
The coating thickness of HPGI can exceed 60 μm, which is significantly higher than that of standard PPGI panels, providing enhanced durability, corrosion resistance, and surface integrity. Thanks to the thick and uniform coating layer, the panel demonstrates excellent resistance to chemical disinfectants and sterilization agents. Its VHP (Vaporized Hydrogen Peroxide) resistance can reach up to 25 days, making it highly suitable for GMP-grade cleanroom environments requiring frequent sterilization.
With its smooth, seamless surface, strong adhesion, and long service life, the HPGI panel effectively reduces maintenance costs while maintaining high cleanliness standards. Combining outstanding performance with reasonable cost, the high-performance spray painted sandwich panel (HPGI) is widely recognized as the best solutions for modern cleanroom wall and ceiling systems.
