Inorganic Pre-Painted Boards, also known as Clean Boards, Solclean Boards, and Antibacterial Boards, are a type of green building material. They are made of high-density, non-asbestos calcium silicate boards with A1 fire-resistant and non-combustible properties. These boards are customized with different colors and patterns on their surfaces according to customer requirements. A special coating process is applied to provide A fire rating, resistance to aging, moisture and water resistance, acid and alkali resistance, and sound insulation. They offer a bright appearance and a sense of cleanliness. Inorganic Pre-Painted Boards are mainly used in public places such as schools, hotels, office buildings, tunnels, subways, and more. Their exceptional performance is particularly evident in high-humidity areas, such as bathrooms, kitchens, and bathing centers.
