First, the special film layer covering its surface can effectively prevent moisture, corrosion and chemical erosion, and adapt to the harsh environmental conditions in cleanrooms, such as high humidity and the influence of chemical gases. Secondly, salt-coated steel plates have excellent anti-fouling properties, which are easy to clean and maintain, ensuring that the workshop is always clean and hygienic. In addition, its excellent wear resistance and corrosion resistance can extend the service life, reduce maintenance costs, and ensure the long-term stable operation of the workshop. Finally, this material also has good decorative properties, which can meet the dual needs of cleanrooms for beauty and functionality.
