3-19mm tempered glass shower door

Tempered window glass is made from annealed glass via a thermal tempering process in which the glass is heated till its softening point about 650 degrees and then quenching quickly to become tempered window glass or heat strengthened glass 


Steps of Manufacturing

Step I First and foremost the right glass combination is selected according to the clients' requirement. The choices are limitless, Clear, Tinted, low-e reflective.

Step II                                 The glass is then cut to size and then its edges are treated. Holes and cutouts are then drilled onto the glass. Then the glass is washed by deionized water and loaded onto the transportation bay of the furnace.

Step III the glass is then transferred into the heating chamber of the tempering furnace. Here the glass is heated till its softening point

Step IV  The glass that comes out at the other end of the furnace is either a fully tempered window glass or heat strengthened glass depending upon the operating cycle set by the operator in accordance with the client's order



 A fully tempered window glass is 3 to 5 times stronger than annealed glass of similar thickness. A fully tempered window glass is regarded as a safety glass and when it breaks it disintegrates into small blunt pieces/ small oval-shaped pebbles which greatly reduce the chances of injuries

1) Strength - Fully tempered window glass is generally 3 to 5 times stronger than annealed glass and twice as strong as heat strengthened glass of similar thickness, size and type. For fully tempered window glass the minimum surface compression is 10000 psi and for a heat strengthened glass is 4000-7000 psi for 6 mm glass.

2) Safety - When broken by impact, fully tempered window glass immediately disintegrates into small oval-shaped pebbles, thus greatly reducing the likelihood of cutting person
