Tempered Glass

What it is?
Popularly known as ‘Toughened Glass’.
An annealed glass is heated to its softening point temperature of  -  degree celsius then it is moved for quenching. The quenching begins at a glass temperature of  - . The quenching cause compression on 20% surface area of glass and edges remaining 60% middle part develops stress zones as a result glass becomes stronger on surface and edges.

Advantages :
It is 4 to 5 times stronger than an annealed glass & twice stronger than a heat strengthened glass.
On breaking a tempered glass shatters into small size oval shaped pieces having blunt edges thus reducing possibility of human injury to a big extent.

Application :
For glazing elevation, door, windows, partitions, and etc., wherever safety is required.
