What is Low Iron Clear Float Tempered/Toughened Glass?

Low Iron clear float also named Ultra-clear glass. It is made by                                                            matured technical operation norm. It looks just like colorless                                                                  crystal with higher transmittance.

Low Iron Clear float tempered/toughened glass is low iron clear (ultra clear) float glass that has been processed through a tempering oven to increase its strength to resist impact, mechanical loads and thermal stress breakage.

Glass is heat-treated by heating annealed glass to a temperature of approximately 1,150°F (621°C), then rapidly cooling it. The glass is cooled by a carefully controlled airflow (also known as quenching), which uniformly cools all glass surfaces simultaneously.

It is approximately four times stronger than annealed glass of the same thickness and configuration. When it is broken, tempered glass fractures into small fragments that reduce the probability of serious injury as compared to annealed glass
