1, What is tempered float glass?
Tempered float glass is made by processing a large float glass sheet to cut to custom size glass panels and later edgeworked before entering the tempering furnace. After enduring the 700 degrees temperature in the tempering machines for several minutes and later cooled down by a strong wind jet to make the glass surface in a compressed status whereas the interior still in tension. This tempering process is also called glass quenching. Tempered float glass will be 5 times stronger than normal float glass, with tempering stress over 90Mpa, which can endure a strong impact without breaking.
Even when the tempered glass is broken due to extremely high impact, the glass will be shattered into small pieces which will be harmless to humans, therefore it is also called safety glass.

3, What is the difference between annealed float glass vs tempered glass?
|Item||annealed float glass||tempered glass|
|Breakage||Pieces with sharp edges||Small particles with obtuse angles|
|Heat thermal stability||Normal||Good can endure high up to 250℃|
4, What are the applications of tempered glass?
Fully tempered float glass has super high strength and safety function, therefore most construction projects such as facade, railing, windows, doors, shower room, showcase, etc will adopt it.
