Tempered or heat-strengthened glass is made by heating flat glass to 700℃ and suddenly chilling of it with jets of cold air. It results the surface under powerful compressive stress and interior with severe tensile stress. The compressive stress on the surface of tempered glass can reach 90Mpa and 4~5 times harder than ordinary annealed glass, while heat-strengthened glass, compressive stress about 24-69Mpa and 2~3 times harder than ordinary.
Features：
High safety. Once breakage occurs, the glass disintegrates into small cubical fragments which are relatively harmless to human body.
It can endure more loads.
It can resistance against sudden temperature changes at the range of 3000C.
Applications:Automobile, train, vessel, architecture, furniture, automatic door, escalator, fireplace, etc.
