Introduction to Tempered Glass
Tempered glass, also known as toughened glass, is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. The process of tempering creates internal stresses within the glass, which gives it enhanced resistance to breakage. When tempered glass does break, it shatters into small, relatively harmless pieces rather than large, sharp shards, making it a popular choice for applications where safety is a concern. Tempered Glass

Tempered glass is widely used in various industries. In construction, it is used for windows, doors, curtain walls, and glass partitions. In the automotive industry, it is used for side and rear windows. It is also used in household appliances, such as ovens and refrigerators, and in consumer electronics, like smartphones and tablets.
