U-shaped glass, also called groove glass, is a new kind of building profiled glass, which has been produced and used for nearly 40 years abroad. Because of the u-shaped cross-section, it has higher mechanical strength than ordinary flat glass and has interest in light transmission, better sound insulation, heat insulation, can save a lot of metal materials, as well as the benefits of construction precision, etc. 

 it is suitable for building interior and Exterior Wall, distance, roof and window, etc. . And we often shallow to explain as a kind of u-shaped glass, u-shaped glass is often used in our lives, but we also lack some correct understanding of it; According to the color, appearance and strength can be divided into three categories: from the color difference, there are colorless and colored; from the appearance of the difference between flat and embossed; from the strength of the difference between Wire Mesh and non-wire Mesh. In our country, materials appeared in the late 1970s. As the glass consumer enterprises and related building parts of this glass are very strange, so this new building glass has never been developed, let alone the promotion and application. With the continuous opening of our national economy and the advance of the living and dying level of our citizens, under the joint efforts of the planning part, the consumption part and the circulation category of our architecture and decoration design, this new type of building glass in our country must be able to be promoted and used to achieve rapid opening. 

The production methods of u-shaped glass are calendering, rolling and casting, but calendering is still widely used. Therefore in our country the construction and the industrial occupation u-shaped glass useful is more widespread. 

U-type glass design and Planning Methods:

1, the appearance of many disposal methods, general fine grain pattern, clear type, colorful, etc. , design planning in addition to general fine grain pattern, other types of requirements indicated. 

2, due to the non-flat materials, we can do a good job of fire grade, if there is a special request in accordance with the relevant standard design plan indicated. 

3. The equipment approach is referred to in the equipment assembly approach, where double-row wings are commonly used to place hollow equipment in pairs at the seams, perhaps with single-row wings facing inward or outward. 

4. For external walls, the length of the installation depends on the local wind load, the height of the glass from the air, etc.
