Heat Strengthened Glass

Heat Strengthened Glass is a heat treated glass with a residual surface compression greater than 3,500 psi and less than 10,000 psi, or edge compression greater than 5,500 psi and less than 9,700 psi. This glass complies with stringent internationally standards such as ANSI 97.1, BS 6206 and AN/NZS 2208.

Heat Strengthened Glass has a lower residual stress and is only 2 times stronger than ordinary glass. It is not considered a safety glass (if use in single piece) and if broken, forms large pieces.

  • Feature
  1. Twice as strong as annealed glass from the same thickness.
  2. Higher bending strength and more resistant.
  3. Heat strengthened glass offers good resistance to thermal stress.
  • Application

When heat treated glass is necessary, CSSG recommends the use of heat strengthened glass for applications   that  do not specifically require a safety glass product.
