Under normal circumstances, most of the building is tempered glass as a cooling medium for the manufacture of physical tempered glass. Tempered glass can be used float glass, flat glass, embossed glass, coated glass, Frosted glass (acid) manufacturing, can also be carried out in the glass after the steel processing re-coating. Tempered glass can be processed into flat products, but also processed into curved products. 

Compared with the ordinary annealed glass of the same thickness, the tempered glass can withstand a larger external strain, and the increase of its resistance to the strain depends on the extent of the glass tempering treatment. Toughened glass is the general impact strength of annealed glass 3 to 5 times, there is a strong resistance to external impact throwing objects and the ability of human impact. The flexural strength of tempered glass is 2 ~ 5 times of ordinary annealed glass, and it has strong wind-resisting load. The temperature range of tempered glass is 250 ~ 320 ℃, while the ordinary annealing glass is only 70 ~ 100 ℃. So tempered glass has strong resistance to temperature mutation ability. 

When the toughened glass is broken, the whole glass plate is broken into smaller particles. Debris corners are blunt, greatly reducing the degree of damage. Toughened glass because of these good mechanical strength and unique way of breaking is called safety glass. While annealed glass will damage human beings after broken. It is not a good material in current building glass market.
