The U-shaped toughened glass is a kind of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are generally used to form compressive stress on the surface of the glass. When the glass is subjected to external forces, the stress on the surface of the glass should be counteracted, then improved the bearing capacity, enhance the glass itself wind pressure resistance, heat and cold, impact, etc. 

First, the strength than the general glass progress several times, bending. The bending strength is 3 ~ 5 times of the general glass, the impact strength is 5 ~ 10 times of the general glass, the progressive strength together also improved the safety.

The second is the use of safety, its load-bearing capacity increased to improve the fragile nature, even if the U-shaped toughened glass damage is also no acute angle of small debris, damage to the human body greatly reduced. The resistance of U-shaped toughened glass to rapid cooling and rapid heating is 2-3 times better than that of ordinary glass. Generally, it can accept temperature difference above 150 LC, which has obvious effect on avoiding thermal burst.

The U-shaped toughened glass is used to cool the surface of high quality float glass rapidly when it is heated near the softening point, so that the contraction stress is spread on the surface of the glass, while the tensile stress is in the center layer. Because there is a strong and equal contraction stress, the tensile stress that occurs under external pressure is counteracted by the strong contraction stress of the glass, and then the safety of the glass is added.

Safety: When the glass is broken by external forces, the fragments into similar honeycomb-like small blunt angle particles, not easy to cause damage to the human body.

High Strength: U-shaped toughened glass of the same thickness are 3-5 times stronger in impact and 3-5 times stronger in bending than normal glass.

Thermal stability: the U-shaped toughened glass has good thermal stability, can accept the temperature difference is three times the general glass, can accept the temperature change of 200 ° C.
