Toughened Glass

Toughened glass, also called tempered glass or ESG, is a type of safety glass processed by heating annealed glass (float glass and patterned glass) to a softening point about 650 degrees, then quenching rapidly to increase glass mechanical strength which is five times stronger than annealed glass. When broken, the glass will break into small granular particles to prevent hurting people.

Curved toughened glass, by the heating annealed glass (float glass and patterned glass) to a softening point about 650 degrees, when quenching begins, the glass sticks to a unique mold with a specific radius.


  • Quality Standard: GB15763, AS/NZS2208, EN12150, ASTM C 1048
  • Surface Compression: minimum 90 Mpa (13000 Psi)
  • Product Certificate: CCC, AS/NZS2208, CE, SGCC

Tempered Glass Features

High mechanical strength: firstly, it is 4-5 times stronger than annealed or untreated glass.

Thermal stability: secondly, it withstands 250 degrees temperature variation, suitable for extreme climates.

Extreme safety: thirdly, it will break into obtuse, small particles if broken, to minimize the possibilities of hurting people.

No need further process: lastly, after being toughened, the glass cannot be cut, drilled, or subjected to any other physical process.

Tempered Glass Benefits

Safety: with high mechanical strength, therefore toughened glass can protect your family from outside accidental threats.

Stability: high thermal stability, in other words, it can endure high temperature in extreme climates and under extreme conditions.

Security: the toughened glass will break into blunt particles, so it is much safer than sharp pieces of annealed glass.

Easy to operate: moreover, it is easy to transport and install, is more robust, endurable, and comes in a fashionable design.

Defects & Measures:

  • Spontaneous breakage or self-explosion
  • Surface distortion in the tempering process
  • Heat soak test, using high-quality float glass
  • Buy glass from reputable factory with a state-of-the-art furnace

Applications: it is a kind of safety glass, and therefore it will be the first choice for windows and doors, facades and curtain walls, balustrades and handrails, pool fencing panels, shower systems, and glass partitions.
