Tempered Glass

Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass.
Thickness: 3mm -25mm
Min size :100mm*100mm

Tempered glass -Toughened Glass -Tempered Glass in China 
Tempered glass is one kind of high-strength glass with even compressive stress on the surface which is made by heating float glass to nearly softening point and then cooling it down rapidly by air.


1.Times harder than ordinary float glass, stronger resistance to thermal breakage than annealed or heat strengthened glass.

2.Once breakage occurs, the glass disintegrates into small cubical fragments, which are relatively harmless to human body.

3.It withstands abrupt temperature change of 220 Centigrade.


Tempered glass is safety glass, which is widely used as window glass, door glass, curtain wall glass, fencing glass in buildings, hotels, curtain wall, etc

1: What is tempered glass?
The process of tempering glass is to heat the original glass to a very high temperature and then quickly cool it down to form a compressed surface on the glass. According to the shape, it can be divided into full tempered glass and heat strengthened glass (also called semi-tempered glass).

2: What are the characteristics of tempered glass?
Tempered glass is 3-4 times stronger than ordinary glass. Under the action of external force, it will be broken into bean-sized pieces to reduce or avoid harm to the human body. Tempered glass has the advantages of high accuracy, low self-explosion rate and no stress defects.

3: How do we know that glass is toughened?
Through, it is impossible to know whether the glass is tempered by observation or touch. You can use a break test or you can check the logo on the tempered glass.

4: Can glass be supplied in any thickness?

 We can provide 3mm-25mm tempered glass .

The tempered glass will sometimes self-blast due to the characteristics itself. The cause is about the NiS , which turns into instability after heating and sudden cooling. The possibility of self-destruction is low, yet it can't be wiped out. To minimize the chances of self-blast, we have large heat-soaked furnace to detonate the potential danger of the tempered glass. Once being heat-soaked, the self-destruction probability will be reduced from 1/1000 to 1/100,000.

Sturdy plywood wooden box, can also be customized according to customer requirements
