Toughened glass

The toughened glass is made from out of annealed glass through the process called thermal tempering to give the glass the required strength. This type of glass is 4-5 times stronger than a simple annealed glass and is more resistant to the thermal stress. Toughen glass can bear up to 295oC as against the simple annealed glass that can withstand only up to 40oC-50oC.

Description

Heat strengthened glass is similar to toughen glass. The most important factor of heat strengthened glass is that is has very less wave distortion as compared to fully toughen glass.

This glass breaks into slightly bigger pieces and move towards edges. It is approximately 2-3 times stronger than annealed glass.

WE have one of the largest toughening plant in Gujarat having capacity of producing the maximum size of 3660mm * 2460mm with wide range of thickness from 4mm to 19mm. We have facility to perform toughening process for high profile glasses such as, Reflective glass. ST series glass and KT series glass.

Due to the enhanced strength, a toughened glass finds a variety of uses in:

  • Capsule Lifts
  • Furniture
  • Glass
  • Glass facades
  • Heat proof
  • Home, Banks, Airport, Hotels, Schools, Hospitals, Offices Building
  • Interior Decoration
  • Partitions
  • Shower cubicles
  • Sliding & Swinging Doors
  • Structural Glazing
  • Windows
Bending Strength 120-200 N/mm2
Conducive for Processing Cannot be cut after Toughening
Design Stress for Architectural Purposes 50 Mpa
Fragmentation Small round crystals
Mechanical Strength 4-5 times stronger than annealed glass
Surface Compression 95 Mpa
Tensile Strength 65 Mpa
Thermal Shock Resistance Up to 250°C
  • Increased tensile strength
  • Thermal shock resistant
  • High heat withstanding capacity
Properties Normal Glass Toughened Glass
Manufacturing Simply melting the ingredients – soda ash, sand and lime at high temperatures and cooling it. Made by annealing the normal glass. Annealing is a process of reheating and cooling in order to retain the strength.
Strength Strong 4 times stronger than normal glass
Breakage Easily shatters into large pieces Hard to break and on breakage it breaks into tiny pieces
Safety If broken, can cause serious injury to people around. If broken, can cause mild cuts to people around but is not life threatening.
Applications Glass jars, containers, mirror, window panes, etc. Capsule lift, sliding & swinging doors, partitions, shower cubicles, etc.
