1)Tempered glass


Tempered glass is one kind of safely glass being produced by heating flat glass to its softening point. Then on its surface forms the compressive stress and suddenly cool down the surface evenly, thus the compressive stress again distributes on glass surface while the tension stress exists at the center layer of the glass. The tension stress caused by outside pressure is counterbalanced with the strong compressive stress. As the result the safety performance of glass is increased.


2)Fine performance


Tempered glasss anti-bent strength, is s anti-strike strength and heat stability are 3 times, 4-6 times and 3 times to ordinary glass, no harm to person. When used as curtain walls its anti-wind coefficient is much higher than the ordinary glass.


Tempered Glass: Float glass that is heated and then cooled rapidly to make it several times stronger than annealed glass. Tempered glass is safer than annealed glass because when it is broken it falls into pebble-like pieces without sharp edges.

FeaturesWith high strength, good thermal stability and safety. No sharp edges on broken fragment.Performance Comparison Between Tempered Glass and Normal Glass

GB/T9963-1998 Tempered GlassGB 17841-1999 Tempered Glass and Heat-strengthened Glass for Curtain Wall



Tempered glass is mainly used for glass curtain walls, up-scale shopfronts, shower rooms, escalator rails, windows and doors on balcony, glass partition and areas where glass may have great potential in causing human damages such as public stadium where people are crowded.


No tong marks on the glass as TG adopts the horizontally tempering process. 5 times harder than ordinary annealed glass. Once breakage occurs,the glass disintegrates into small cubical fragments which are relatively harmless to human body. It withstands abrupt change of temperature..For example ,a piece of 5mm tolerate the temperature variations within the range of 200.
