The high-quality GRC board uses alkali-resistant glass fiber as reinforcement material, and the sulphoaluminate low-alkalinity cement is cementitious material and is blended with a suitable aggregate to form a base material. It is made by eruption, vertical mold casting, extrusion, and flow-through. New inorganic composite materials. It has characteristics of light weight, high strength, high toughness and water resistance, non-combustibility, sound insulation, heat insulation, corrosion resistance, and easy processing. GRC technology can produce Roman columns, twist lines, waist lines, door covers, window covers, roof covers, window side columns, lightweight partition boards, variable pressure flue, railings, garden reliefs, Tibetan components, antique components, There are hundreds of species such as mountain flowers, pillars, and cultural stones. The surface of the components is smooth and exquisite. The stripes are vivid and expressive, they are perfect in shape, and they have a strong sense of art.
