U型玻璃（亦称槽型玻璃）是用先压延后成型的方法连续生产出来的，因其横截面呈“U”型，故得名。U型玻璃品种很多，有着理想的透光性、隔热性、保温性和较高的机械强度，不但用途广泛、施工简便，而且有着独特的建筑与装饰效果，并能节U型玻璃（亦称槽型玻璃）是用先压延后成型的方法连续生产出来的，因其横截面呈“U”型，故得名。U型玻璃品种很多，有着理想的透光性、隔热性、保温性和较高的机械强度，不但用途广泛、施工简便，而且有着独特的建筑与装饰效果，并能节约大量轻金属型材，所以被世界上许多国家的城乡建筑所采用。约大量轻金属型材，所以被世界上许多国家的城乡U型玻璃采用的标准：

U型玻璃采用标准：

A.建筑用玻璃EN 572-7

B.建筑工程质量检验评定标准GBJ301-88。

C.装饰工程施工及验收规范JGJ73-91。

U-shaped glass (also known as groove glass) is continuously produced by the method of calendering and then forming. U is a wide variety of glass, has the ideal pervious to light quality, thermal insulation, heat preservation and high mechanical strength, not only widely used and the construction is simple, and has a unique architectural and decorative effect, and can section of u-shaped glass (also known as slot type glass) method is to use after the first rolling forming continuous production, because of its cross section is "U" type, so its name. U type glass varieties are many, with ideal light transmittance, insulation, thermal insulation and high mechanical strength, not only widely used, simple construction, and has a unique architectural and decorative effect, and can save a lot of light metal profile, so it is used in many countries in the world. About a large number of light metal profiles, so many countries in the world's urban and rural u-glass standards:

Adoption criteria:

A. glass for building purposes EN 572-7

B. Construction quality inspection and assessment standard gbj301-88.

C. Code jgj73-91 for construction and acceptance of decoration works.
