product description：
heat-strengthened glass differs from tempered glass in its surface compression; its mechanical strength is about 1.6-2 times that of annealed glass. heat-strengthened glass has outstanding thermal stability, and its flatness is close to that of annealed glass and better than that of tempered glass.
product features：
safety: when broken, tempered glass becomes small granules, which prevent substantial hurt to human body.
high strength: the strength of tempered glass is 4 to 5 times that of annealed glass.
thermal stability: tempered glass has excellent thermal stability, which can withstand up to 300℃ thermal shock.
application areas：
tempered glass is a safety glass and is widely used in places where mechanical strength and safety are high, such as: glass doors, building curtain walls, facade windows, indoor partitions, furniture, near heat sources and hot and cold shocks cut off and so on.
