Tempered Curved Glass

Offering curved tempered glass, curved heat-strengthened glass, oversized curved glass, or custom curved toughened glass with cylindrical curved and non-cylindrical curved forms including J-curved, S-curved, Free form 3d curved glass, double curved, multi-radius curved, tangent curved glass.

What is AJJ Tempered Curved Glass

Bent tempered glass

Through a manufacturing process of heating, curving, and rapidly cooling the glass, curved tempered glass is 4-5 times stronger than annealed glass and can be used in applications requiring safety glazing and structural glazing. Curved Heat-Strengthened glass is also available. Heat-strengthened glass is 2 times as strong as annealed glass. While not a safety glazing product, it is used in applications requiring additional strength for load specifications or applications and glass types requiring thermal absorption resistance.

State-of-the-art technology provides high-quality optics with minimal distortion and strict radial tolerances.

Tempered curved glass can be manufactured as a tempered/laminated product, or combined in an insulated unit for increased thermal and solar performance.


The result of our company’s development work has come with several significant innovations like the bending methods applied to demanding spherical, conical, and parabolic glasses. 

Jumbo and Bespoke Glass Measurements

Thanks to our state-of-the-art glass bending machine, AJJ can redefine possibilities by offering a tempered curved glass of impressive dimensions, reaching up to 3600mm in arc length and 18000mm in height depending on the glass makeup, coatings, and bending geometry.

America Standards:

  • ANSI Z97.1 – Safety glazing materials used in buildings. This standard provides guidelines for safety glazing materials in residential and commercial applications, including tempered glass. It specifies the performance criteria for impact resistance and requires glass to meet certain fragmentation requirements.
  • ASTM C1036 – Flat Glass.
  • ASTM – C1048 – Heat-treated flat glass. This standard sets the minimum requirements for tempered flat glass. It covers glass thickness, surface compression, and fragmentation characteristics.
  • CAN/CGSB 12.1 – Safety or laminated glass,
  • CPSC 16 CFR- 1201 – The Consumer Product Safety Commission (CPSC) standard in the United States sets the requirements for architectural glazing materials, including tempered glass. It tests the glass for impact resistance and establishes different categories based on the glass thickness and the drop height required to break it.

Australian Standards:

Architectural – 4mm to 12mm Grade ‘A’ safety glass manufactured to AS/NZS 2208-1996 Safety glazing materials in buildings and 15mm to 19mm Toughened glass.

The Australian/New Zealand standard for safety glazing materials assesses the impact resistance of tempered glass. It classifies glass based on the drop height required to break it and provides guidelines for its use in different applications.

British & European Standards

  • BS 6206 - ' Code of practice for glazing for buildings'. Part 4: 1994 'Safety related to human impact'
  • BS EN 12600:2002 - Glass in building. Thermally toughened soda lime silicate safety glass.
  • EN 12150:2015 - This European Standard specifies tolerances, flatness, edgework, fragmentation, and physical and mechanical characteristics of monolithic flat thermally toughened glass.
