Tempered glass, also known as toughened glass, is a safety glass manufactured through thermal processing. Its strength exceeds ordinary glass by 3-5 times. The process involves heating glass to 620°C followed by rapid cooling, creating a surface compressive stress layer and internal tensile stress layer, enhancing impact resistance and thermal stability (withstanding 200°C temperature differences). When shattered, it breaks into honeycomb-like blunt-angled particles, minimizing injury risks.

Tempered glass is widely used in architectural and daily life applications. In construction, it is commonly employed for high-rise curtain walls, glass doors/windows, skylights, and glass walkways, where its wind resistance and impact resistance ensure safety. In residential settings, it is used for shower enclosures, furniture countertops, and room partitions, with its blunt-angled fragmentation reducing injury risks.
