Tempered Glass is a kind of safety glass as its surface has strong and uniform pressure stress and multiplied mechanical strength after heating and quenching treatment. Semi-Tempered Glass is produced by a process similar to that Tempered Glass at lower cooling speed, so its surface stress is slightly less than Tempered Glass, and semi-Tempered Glass isn't safety glass. The toughness glass as safety glass is widely used for places with higher requirements on mechanical strength and safety, such as glazed door, building curtain wall and partition which is close to heat source and suffers from severe cold and hot shock. It can be used singly or made into sandwich or hollow product as required.

Features of Tempered Glass

1. Safety: Break up into small granules which have uniform obtuse angle and are not easy to hurt people
2. Strength: Its strength is 4-5 times of common glass.
3. Heat Stability: Endure temperature difference of 200°C

Features of Semi-Tempered Glass

1. Safety: Once falling apart, the crack of semi-toughened glass extends to side, and its fragment can be kept in the framework and doesn't fall.
2. Strength: Its strength is 2-3 times of common glass.
3. Heat Stability: Effectively resist thermal stress to avoid heat burst
4. Compared with Toughened Glass: It has better flatness, and is not easy to generate self-destruction of toughened glass.
