Toughened Glass

We manufacture and supply excellent quality Toughened Glass which is reckoned as a safety glass. The Toughened Glass is processed by controlled thermal treatment to increase its strength. Fabricated with utmost precision, our Toughened Glass comes in numerous shapes, sizes, thicknesses and dimensions. It is made from annealed glass that is heated to approximately 650^oC and then rapidly cooled. Our Toughened Glass is widely acclaimed for higher thermal strength and ability to withstand high temperature differential up to 250^oC. It has excellent light transmission and solar radiant heat properties. Our Toughened Glass is inexpensive to afford. Our Toughened Glass is made through a rigorous heating and cooling procedure that makes it 5 times stronger than float glass. Our Toughed Glass is commonly used for glazed doors, low-level windows (below 800mm) tabletops and glass shelving. In order to retain the reliability and quality of our SafetyToughened Glass , we fabricate them following international quality standards and norms.

Production Process :

• The basic principal employed in the heat-treating process is to create an initial condition of surface and edge compression. This condition of surface and edge compression is achieved by first heating the glass and then cooling the surfaces rapidly.
• This leaves the center glass thickness and then cools; it forces the surfaces and edges into compression.
• In the “heat-treatment” process, the key element is an application of a rapid air quench immediately upon withdrawal of hot (approx.650^oC) glass from the “tempering furnace.” The immediate and sustained application of an air quench produces the temper.
• As air direction against hot glass from arrays of fixed, reciprocation or rotating blast nozzles, it is important to extract heat uniformly from both surfaces(uneven heat extraction may produce bow or warp) and to sustains the quench long enough to prevent reheating of the glass surface from the still-hot glass core.
• A quenched condition becomes stable when the glass is reduced to a temperature of approximately 400-600^oC.

Applications :

• Toughened Glass is used traditionally in place of other glass products in application requiring increased strength and reduced likelihood of injury in the event of breakage. The building industry, motor vehicle industry and certain manufacturing industries fine Toughened Glass effective and economical in a wide range of application.
• Toughened Glass can also be used for doors, sidelights, shower and tub enclosure, and interior partitions. It is also used in storm doors. Patio-door assemblies and stairway balustrades.
• As a glazing product, it is used in windows and in spandrel areas, sloped glazing, racquetball courts, skylights and solar panels. Manufacturing industries use Toughened Glass in refrigerators, furniture, ovens, shelving, and fireplace screens.

Key Features :

• Strength
• Safety
• Resistance to thermal breakage

Limitations :      

• Glass cannot be cut or altered after tempering.
• The raw material used in the manufacturing of Toughened Glass is not free from certain defects, like Nickel Sulfide inclusions, which put it at potential risk of spontaneous breakage.
• Toughened Glass has some roller marks and more distortion than annealed glass.
• Toughened Glass as single glass should not be used for critical applications like overhead glazing where humans may walk.
