Tempered glass Introduce :
Noval Tempered Glass and Heat Strengthened Glass is formed by heating glass to the softening point in a horizontal tempering stove and then quickly cooling it with cold air., This technique resists compressive stress on the surface and tensile stress inside which provides bending/shock resistance.
Tempered characteristic:
1.When broken, it splits into tiny harmless pieces. Grade A safety glass as per AS1288;
2.Safety(tempered).
3.Strong intensity. Heat-strengthened glass is approximately twice as strong as annealed glass of the same thickness, and tempered glass is about 5 times.
4. Outstanding performance in resisting thermal stress and wind-load.
Tempered glass Application :
1.Places where safety glass is required to be used by laws and regulations,.
2.Windows or other area in a building.
3.Glass balustrade and escalator sidepanels.
4.Windows of motor vehicles, boats and ships.
5.Glass table tops and show shelves, Interior decorations and furniture, Places exposed to thermal impact.
6. recommended for door, side and low lites, frameless entries, balustrades, shower, bath screen panels and furniture;
Tempered glass Specification:
Maximum size: 3660*120000mm
Minimum size: 200*200mm
Thickness: 2.8~25mm
Standard : GB/T 9963-1998 AS/NZS 2208-1996 EN 12150 JIS R 3206-1989 BS 6206
DID YOU KNOW?
1. toughened glass cannot be drilled or edgeworked in any manner. Sandblasting or other surface treatments should be carried out prior to toughening as per AS1288 - 1994. Deep sandblasted patterns greater than 1mm are not permissible;
2.toughened glass ordered to templates must be accompanied with a full scale template made to the correct dimensions. These must be made from a rigid material. Orders submitted with complex drawings and sizes to avoid template construction will either be rejected or executed at the customer? risk;
3. minimum edgework finish on toughened glass up to 12mm is a standard arrissed edge. Minimum edgework on greater thicknesses should be a flat ground edge;
4.slight distortion or bowing may occur after toughening but is largely controllable. It will vary with substance, tint, surface treatment, size and shape of the glass. Ceramic painted, sandblasted or reflective coated glass has a greater tendency to bow and special tolerances would be advised. Flatness will be measured when the glass is standing on edge with a straight edge placed along the full length of the panel and a wedge measurement taken at the centre position. Refer to our technical department for more information;
5. the roller motion process during the furnacing of glass panels can produce slight corrugated distortion or roller waves. This visual effect is in the form of distortion bands 250 - 300mm apart. It is most noticeable in reflective toughened glass and should be glazed horizontally;
6.not recommended for overhead glazing and structural balustrades with no hand rails above ground floor;
7. plastic wrap on toughened glass should be removed no later than one month after exposure to sunlight.
