Cleanrooms are specially designed environments aimed at maintaining controlled levels of contamination, which are critical in industries such as pharmaceuticals, electronics, and precision manufacturing. These rooms are equipped with advanced air filtration systems, strict temperature and humidity controls, and automated monitoring to ensure sterile and efficient production processes. Color-coated steel coils (PPGI and PPGL) are commonly used in the construction of cleanrooms, providing durable, easy-to-clean surfaces that meet the high hygiene and safety standards required in such environments. Aoguan's antibacterial, anti-static, or purification board color-coated coils, used to make sandwich panels, offer the main advantages of long-lasting antibacterial effectiveness, durable substrate characteristics, and cleanroom performance that meets stringent environmental requirements, making them suitable for use in hospitals, food workshops, and cleanrooms.
