6mm inorganic pre-coated panels are widely used in various indoor wall applications such as food factories, laboratories, subways, tunnels, schools, sports venues, laundries, and office buildings. Their performance is especially evident in humid areas like kitchens, bathrooms, and balconies. These boards, also known as clean boards or fire-resistant boards, are made of non-asbestos calcium silicate as the base material, coated with UV paint for surface treatment, offering effective fire resistance, aging resistance, water resistance, and maintaining a bright appearance, conveying a sense of cleanliness.
