Our Tempered Glass Products
Tempered glass description
Toughened Glass is to heat the glass to a temperature lower than the softening temperature, and then conduct uniform and rapid cooling. The outside of glass will be fixed due to rapid cooling, while the inside will continue to shrink, resulting in compressive stress on the surface of glass and tensile stress on the inside. To break the tempered glass, the internal stress must be offset first, so that the mechanical strength and thermal stability of the glass are improved.
Features of Tempered Glass
- Strictly meet with building codes and safety requirements
- Strong enough to withstand high levels of thermal stress
- 3-5 times stronger than annealed glass of the same thickness
- Breaks up into small cubical fragments, not threatening to humans
- All customized processing on glass must be done before tempering
- Can be printed with special logo and patterns with enamel silkscreening
- Accept different kinds of custom design
