Curved tempered glass, also called bend tempered glass or bent toughened glass, is a type of safety glass that’s made using the same method as tempered glass. To create it, the glass is heated and then rapidly cooled to create compressive stress that increases its strength. This makes curved tempered glass just as strong as tempered glass. However, because it has a unique shape, it also has better resistance to wind pressure compared to tempered glass.

The most common shape for curved tempered glass is an arc. The process starts with float glass being heated until it becomes soft, and then it's bent into the desired shape using either its own weight or external pressure. Afterward, the glass is uniformly and rapidly cooled to create the final product.
