Tempered glass is commonly used in most sliding doors due to its strength and safety features. This type of glass undergoes a special heat treatment process that makes it significantly stronger than regular glass. In the event that it shatters, tempered glass breaks into small, dull pieces, reducing the risk of injury. This safety property is especially important for sliding doors, which are often located in high-traffic areas of homes and commercial buildings. Additionally, the clarity and aesthetic appeal of tempered glass make it a popular choice for providing unobstructed views while ensuring durability and security in the design of sliding doors.
