guangzhou building material price glass aluminum curtain wall

curtain wall glass  is made of tempered glass.

Tempered glass is made by heating flat glass to just below its softening temperature and suddenly chilling it with jets of cold air. It results in the outer skins under powerful compressive stress and the interior with severe tensile stress. In consequence, the impact applied to the glass will be overcome by the compression stress on the surfaces to assure safety of use.

Features:

1, 5times harder than ordinary float glass.

2, once breakage occurs, the glass disintegrates into small cubical fragments, which are relatively harmless to    

      human body.

3, it withstands abrupt temperature change of 220 centigrade.

4, sizes are produced as per customer request. Once tempered, it can no longer be cut drilled or ground or

     any other special processing.

Application:

     Tempered glass is a safety glass and is widely used in those occasions putting forward a very high demand for the mechanical strength and safety, such as glass doors, buildings’ curtain walls, indoor partitions, elevators, show windows, skyscrapers, vehicles, automobile, building’s major face windows, furniture and household electric appliances.
