Basic Info

U profile glass or called U channel glass originates from Austria. It also is produced over 35 years in Germany. As one of the typical materials which are used in large-scale building projects, U profile glass is applied extensively in Europe and America. The application for U profile glass in China is dated from the 1990s. And now many areas in China use it for its international-based design trend.
 
U profile glass is one kind of casting glasses. It is a progress of forming in the computer-control smelting furnace that enables it to keep excellent quality and precision. Its high mechanical strength enables it to be fixed on high-rise buildings and other buildings which need good lighting. And this can save the buildings from extra vertical and horizontal underpinning. U profile glass featured by its good lighting, heat insulation and preservation, sound insulation and noise protection—-it is one of the new type environment-friendly and economical glasses.

Tempering & heat soak testing

We originated the tempering process for U profile glass up to 20′ long and constructed custom tempering ovens exclusively for tempering three-dimensional U profile glass. Their machinery, procedures, and experience yield dimensionally consistent glass.

Tempered LABER U profile glass is annealed channel glass that has undergone a second heat treatment in a tempering oven to strengthen the glass and raise the compression to 10,000 psi or greater. Tempered U profile glass is three to four times stronger than annealed channel glass and is recognized by its break pattern – relatively small, harmless fragments. This phenomenon, called “dicing,” markedly reduces the likelihood of injury to people as there are no jagged edges or large, sharp shards.
