Tempered Glass

Our tempered glass is produced through a physical tempering process. In this method, the formed glass is heated in a controlled manner to a temperature range close to its softening point so that the internal temperature becomes uniform. The glass surface is then rapidly cooled (quenched) using high-velocity air jets. Because the surface cools and solidifies faster while the interior remains at a higher temperature and continues to contract, the completed cooling cycle creates a permanent compressive stress layer on the glass surface, balanced by tensile stress within the core. This stress distribution significantly improves the glass’s flexural strength, impact resistance, and thermal shock resistance, while reducing the risk of fracture caused by the propagation of surface micro-cracks. If breakage occurs, physically tempered glass typically fractures into small, relatively blunt-edged fragments, which helps reduce the risk of cutting injuries. For these reasons, it is widely used in applications requiring both safety and durability, including doors and windows, display equipment, and industrial uses.
