Product Overview:

The surface compressive stress of heat-strengthened glass differs from tempered glass. Its mechanical strength is 1.6 to 2 times greater than regular annealed glass, while also providing superior thermal stability. The flatness of heat-strengthened glass is closer to that of annealed glass but superior to tempered glass.

Key Features:

• Safety: When broken, the glass shatters into small, blunt-edged pieces similar to honeycombs, which pose minimal risk to humans.
• High Strength: Tempered glass is 4 to 5 times stronger than ordinary glass.
• Thermal Stability: It can withstand temperature variations of up to 300°C.

Application Areas:

Tempered glass is widely used in environments where high mechanical strength and safety are required, such as in glass doors, curtain walls, windows, partitions, furniture, and areas exposed to extreme heat or cold.

Semi-Tempered (Heat-Enhanced) Glass Features:

Heat-strengthened glass has a compressive stress level different from tempered glass, with mechanical strength 1.6 to 2 times that of annealed glass. It also maintains good thermal stability and has a flatness similar to annealed glass but better than tempered glass.
