Tempered glass (toughened glass) 4-5 times stronger than annealed glass of equal thickness. Yujing tempered glass is a kind of safety glass that is very popular in building,decoration and automobile field.All work done on glass(beveling, cutting,bending,etc)must be done before tempering.

Tempered glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Quenching sets the outer surfaces in compression and the inner surfaces in tension. Such stresses cause the glass, when broken, to be shredded into small pieces rather than splinter granular into jagged shards. The granular chunks are less likely to cause injury.
Tempered glass is widely used to window, door, railing, partition, shower, table top, ect.
