Tempered glass is kind of glass with regular mechanical stress even increasing times through rush cooling on the float glass after heating. The surface stress is more than 90mpa, and the stress of semi tempered glass is between 24mpa to 69mpa.

Safety: Only small alveolate like obtuse angle granules happened once the tempered glass being broken, which prevent substantial hurt to human body.

High strength: The strength of tempered glass is 4 to 5 times that of float glass.

Thermal stability: Excellent 3times thermal stability than float glass make the tempered glass 300°c thermal shock standing.
