Ice patterns, an organic, severe fuzzy texture, suitable for single glaze to create privacy or hidden view application of metope, u-shaped glass is a kind of most shaped glass used in construction, because of its cross section is u-shaped, improve the stress of the glass, make it has high mechanical strength than flat glass, installation of large span, can save a lot of profiles.

U-shaped glass can be roughly divided into three types according to color, appearance and strength. Distinguishing between flat and embossed from surface states; From the strength of the distinction between the clamping wire clamping net and no clamping wire clamping net. The production methods of groove glass are calendering, rolling and casting, but the common method is calendering. At present, most of the foreign groove glass is colorless. If you want to produce colored groove glass, you only need to send the colorant into the glass furnace with the raw material to stir according to the prescribed dose, so that the glass will be colored evenly. In order to improve the diffuse rate of light or enhance the decorative effect of groove glass, can also be used to carve calender roll, in order to pressure out small patterns on the surface of glass and other ideal patterns. The production cost of the fluted glass is relatively low, with a total energy consumption of 14 kg of standard coal per square meter of production and 56 kg of clay bricks per square meter of production. 6kg standard coal, saving 75% of energy consumption. The average weight of each square meter of clay brick and concrete walling material is 415. Five kilograms, compared with 19 kilograms for fluted glass. If use groove glass more, can reduce wall body weight 90%, economize a lot of building base material. The construction efficiency of channel glass is generally 10 times that of brick walls. With the development of China's construction industry, trough glass will gradually replace brick wall as the main material.

U-shaped glass is mainly produced in Germany, France, Belgium, Hungary, the former Soviet union, Canada and the United States. In 1996, China also introduced the advanced production technology and equipment of groove glass from Germany, and built the first groove glass production line, which filled the gap of glass profiles in China's building materials.
