Cleanroom panels are available in single-panel and composite types. Single-panel products use cement pressure boards as substrates and are used in hospitals, laboratories, equipment rooms and other areas requiring high environmental cleanliness. Composite panels use color-coated sheet, stainless steel or other materials as facings. They are used in cleanroom construction with stringent indoor environmental requirements, including electronics, pharmaceuticals, food, biotechnology, aerospace, precision-instrument manufacturing and scientific research.
