Properties: safety:when broken,it spits into tiny pieces which are not threaten to humans.strong intensity:4-5 tines stronger than annealed glass of the same.outsanding performance in resisting thermal stress and wind load. Description: It is a kind of safety glass, it is 4-5 times stronger than normal glass.Tempered glass heated to softening point around 700°C,through heat treatment processing,then cool it down rapidly and smoothly on the glass sur face so as to bring very strong tensile stress inside of glass and much stronger pressure on its surface,there by increasing the strength and thermal stability of the glass. Application: Tempered glass is a safety glass and is widely used in those occasions putting forward a very high demand for mechanical strength and safety , such as glass doors, buildings curtain walls, indoor partitions, elevators ,show windows, buildings major face windows, furniture and household electric appliances.
