The pharmaceutical industry has high standards for cleanroom flooring.
During the design and construction of cleanrooms in the pharmaceutical industry, cleanroom flooring systems require smooth, flat surfaces, no cracks, tight joints, no particle shedding, and easy cleaning and disinfection to minimize dust accumulation. Ideally, the junction between the walls and the floor should be curved.
