Production Process

TEMPERED GLASS
Tempered glass is produced by heating annealed glass in a furnace to 620C° 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. The result is fully tempered glass 4-5 times stronger than annealed glass of equal thickness.

Features:
1. Tempered glass is a kind of safe glass and the fragment of which does no harm to people.
2. it's 4-5 times safer and harder than ordinary annealed glass.
3. Special logo and pattern can be printed on tempered glass.
4. Outstanding performance in resisting thermal stress and wind-load.
5. Bear sudden temperature change of 220 centigrade degree
