Product type
Heat strengthened glass is a type of glass that undergoes a thermal treatment process to enhance its strength and resistance to thermal stress. This process involves heating the glass to a high temperature and then cooling it rapidly, which creates a compressive stress layer on the surface. It is typically made from soda-lime glass and is known for its durability and safety features compared to standard glass.
| Thickness range | 4mm to 19mm |
| Maximum size | 3000mm x 6000mm |
| Thermal stress resistance | Up to 120°C temperature difference |
| Standard compliance | ASTM C1048, EN 12150 |
| Surface treatment | Available in clear, tinted, or reflective finishes |
When selecting heat strengthened glass, buyers should consider the thickness and size required for their specific application. It is important to specify any surface treatments desired, such as tinting or reflective coatings. Additionally, understanding the thermal stress resistance needed for the environment where the glass will be installed is crucial. Buyers should also inquire about compliance with relevant standards and certifications, as well as the quantities needed for their project.
