Tempered glass

Tempered glass: 1.Strength is 4-5 times of ordinary glass; 2.Thermal stability is 3 times of ordinary glass. Tempered glass is produced by heating annealed glass in a furnace to 620°C. Progressing from the furnace, the glass is rapidly cooled with jets of cold air, inducing compressive stresses to the surface while the center remains tensile. 4-5 times stronger than annealed glass of the same thickness. Stronger resistance to thermal breakage than annealed or heat strengthened glass If breakage occurs the glass breaks up into small, cubical fragments, which are not threatening to humans. Suitable for use as a safety glass as defined by consumer product safety association 16CFR 1201, ansiz 97.1 1984 and BS6262. Conforms to American Standards ASTM C1048. All work done on glass (beveling, cutting, bending, etc) must be done before tempering. Ideal for areas with high wind loads and areas where human contacts is an important consideration, tempered glass is the perfect option for architects who must meeting building codes and safety requirements. Moreover, it is the only glass strong enough to withstand high levels of thermal stress, a common reason for breakage in building facade glazing units (see table below). These safety features also make it an exemplary choice for automotive applications. Guaranteeing quality, Hisuper applies heat soak testing to all of its tempered glass before packaging and loading. It is available in all of Hisupers’ standard float thicknesses and sizes.
