Rock wool large board, as a specialized rock wool for metal faced sandwich board, is widely used in sandwich board rock wool core material, decorative integrated board cotton core material, etc. After being cut and flipped,it has high tensile and compression resistance. At the same time, it has the properties of thermal insulation, fire prevention, sound absorption and noise reduction,etc., which plays a decisive role in improving the overall quality of the color steel sandwich board. With the development of the colorsteel industry, product requi rements are also constantly improvingto ensure that product performance meets and exceeds industry standards.
