TEMPERED GLASS

Tempered glass, also name Toughened Glass, is fabricated by heating annealed glass to over 600°C and cooling it rapidly, which locks the outer surfaces of the glass in a state of high compression, and the core or center of the glass in compensating tension. It is a safety glass which is used when strength, thermal resistance and safety are important considerations.


CHARACTERISTIC

High Strength

The tempered glass performs well in resisting bending and hitting owing to its high strength which is 3-5times that of normal annealed glass. It is able to withstand a surface pressure of 95Mpa.

High Safety

When the tempered glass is broken, it turns into alveolate granules with obtuse angles, which guarantee safety to make sure human harmless, and the toughening process greatly reduces the risk of thermal breakage to ensure less loss.

Heat Stability

The tempered glass is capable of withstanding a temperature change of 250 to 320 while normal annealed glass can only bear 20 to 100.

EDGE WORK

Any edges could be done perfectly, like flat polished edge (T edge), pencil edge (C edge), beveled edge, ogee edge, matt edge, corner round edge.

 

HOLES AND NOTCHES

Tempered glass can be supplied with drilled holes (no matter straight or conical) and cut notches. We will consider hole and notch locations and size according to your drawings.

Please kindly check below details:

Glass edge to nearest point of hole

Glass less than 1/2" thick should not have holes located any closer than 1.5 times the thickness of the glass.  Glass thicker than 1/2" should not have holes located any closer than 2 times the thickness of the glass.

Glass corner to nearest point of hole

Holes should not be located any closer than 6.5 times the thickness of the glass.

Dimension of holes

The minimum dimension of a hole should not be less than the thickness of the glass. The maximum dimension of the hole should not be more than 1/3 the narrowest dimension of the piece.

Notches and cutouts

All must have a fillet with radius equal to, or greater than the thickness of the glass.

 

SHAPES

Except rectangle, we also could do shape tempered glass, like round, Trapezoid, parallel, etc.
