Product Name: Tempered glass door

1. What is Tempered Glass?
Glass that is strengthened through the process of heating and then cooling the surface rapidly is known as Tempered Glass. This process creates surface compression and tensile strength that causes glass to resist breakage, yet disintegrate into small pieces if a break occurs. Fully tempered glass must have a surface compression of 10,000 psi. This process produces glass four times more impact resistant than non tempered glass.
 
2. Feature of tempered glass:
Tempered (toughened) glass is two or more times stronger than annealed glass. When broken, it shatters into many small fragments which prevent major injuries. This type of glass is intended for glass façades, sliding doors, building entrances, bath and shower enclosures and other uses requiring superior strength and safety properties.
 
3. Production methods:  There are two different methods used to produce tempered glass:
I.  Heat treating: Where the annealed glass is subjected to a special heat-treatment in which it is heated to about 680°C and afterwards cooled. If it is cooled rapidly, the glass is up to four times stronger then annealed glass and its breaks into many small fragments (fully-tempered). If it is cooled slowly, the glass is twice as strong as annealed glass and the fragments of the broken glass are linear and more likely to remain in the frame.
II.  Chemical Strengthening: The glass is covered by a chemical solution which produces a higher mechanical resistance. Chemically-strengthened glass has similar properties to thermal-treated glass. The product is not generally used for window glass, but more commonly seen in industries where thin, strong glass is needed.
