Tempered glass is a kind of pre-stressed glass, to improve the strength of the glass, typically using a chemical treatment or physical hardening hardening treatment method, form a pressure in the glass surface, the glass surface exposed to external stress when the first offset, thereby improving the carrier ability to enhance glass itself wind pressure resistance, cold and heat resistance, impact resistance and so on.

    1.Tempered glass is produced by heating annealed glass in a furnace to 620°C. Progressing from the furnace, the glass is rapidly cooled with jets of cold air, inducing compressive stresses to the surface while the center remains tensile. 

Flat glass tempering furnace

  2.4-5 times stronger than annealed glass of the same thickness. Stronger resistance to thermal breakage than annealed or heat strengthened glass

  3.If breakage occurs the glass breaks up into small, cubical fragments, which are not threatening to humans.
