curved 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. Fine performance Tempered glasss anti-bent strength, its anti-strike strength and heat stability are 3 times, 4-6 times and 3 times to ordinary glass respectively. Its hardly brakes under outside action. When broken, it becomes small granules safer than ordinary glass, no harm to person. When used as curtain walls its anti-wind coefficient is much higher than the ordinary glass.
