Hot sale 12mm tempered glass panels used for swimming pool

Maelezo mafupi:

Tempered glass, also called toughened glass, it is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Quenching sets the outer surfaces in compression and the inner surfaces in tension. Such stresses cause the glass, when broken, to be shredded into small pieces rather than splinter granular into jagged shards. The granular chunks are less likely to cause injury.
