Ultra/extra clear tempered glass low iron toughened glass







Ultra/extra clear tempered glass is also called low iron tempered glass, which is made by forming compressive stress on the surface of the glass and heating the glass up to its intenerating temperature and then make the glass uniform cooling quickly. During the process of cooling, the exterior part of the glass is solidified because of the rapid cooling, while the interior part of the glass shrinks because of slow cooling, then forming compressive stress on the surface of the glass and tensile stress inside the glass, thus improving the intensity and heat stability of the glass. Low iron tempered glass can be with holes or cutouts/hinges/grooves/notch and processed into tempered laminated glass, tempered insulated glass, etc.
Standard: EN 12150; ASTM 1048; BS 6206: 1918; GB 15763.2-2005; AS/NZS 208: 1996

Applications:
Low iron tempered glass is safety glass, which is widely used as window glass, door glass, curtain wall glass, fencing glass in buildings, hotels, curtain wall, etc.

Specifications:
Thickness: 3-19mm low iron tempered glass
Color: Clear tempered glass, ultra clear tempered glass, brown tempered glass, golden bronze tempered glass, blue tempered glass, ocean blue tempered glass, dark blue tempered glass, light blue tempered glass, F green tempered glass, light green tempered glass, dark green tempered glass, euro grey tempered glass, dark grey tempered glass, etc.
Max specification:
Flat tempered glass 3000*8000mm
Bent tempered glass 3000*5000mm, R=1500mm

Considering the characteristics of low iron tempered glass, glass size should be confirmed before making production. Once tempered glass size is confirmed, tempered glass can not be made mechanical treatment any more, and otherwise, it will be broken.


Competitive Advantage:

Low iron tempered glass has a very good performance of anti-curve, anti-impact intensity, 3 to 6 times better than normal glass. Tempered glass/Toughened glass can afford pressure over 95MPa on the surface. Tempered glass/Toughened glass has high stability even under temperature change of 200-300 centigrade, while normal glass can only afford change of 70-100 centigrade. Tempered glass becomes small sand shape if tempered glass is broken under big forces, which guarantee safety and less loss.

Safety performance: Low iron tempered glass will appearance hurtless obtuse angles when breakage.
Strength performance: Four times more than ordinary glass.
Heat stability performance: Three times more than ordinary glass, could bear the temperature change about 200° C.

1. Safety
2. Tempered glass has 4-5 times strength than ordinary glass
3. Hot stability
4. Generously satisfy with different clients' requirement to meet different designs

Low iron tempered glass is often referred to as safety glass because it is more resistant to breakage than normal float glass. Yet if it is broken, it usually breaks into relatively small pieces, which are less likely to cause serious injury.
