Spherical Tempered Glass | Glass Manufacturer

Spherical tempered glass is a type of tempered glass with a spherical curvature. Its complex manufacturing process combines high strength, safety, and unique aesthetic appeal. It is widely used in architectural domes, observation decks, high-end lighting fixtures, and other applications requiring a distinctive design. Spherical tempered glass is ideal for iconic structures such as observatory domes and spherical exhibition halls.

Features

Mechanical Performance Advantages
- High Strength: After tempering, the bending strength reaches 120–200 MPa, which is 3 to 5 times stronger than regular glass, significantly improving impact resistance.
- Wind Pressure Resistance: The spherical structure evenly distributes loads, making it especially suitable for dome buildings, capable of withstanding strong winds or snow pressure.
- Thermal Stability: The tempering process reduces the risk of thermal expansion and cracking, allowing the glass to adapt to temperature changes ranging from -40°C to 300°C.
Safety Features
- Safe Breakage: When broken, the glass shatters into small, blunt-edged particles (complying with GB 15763.2 or EN 12150 standards), minimizing the risk of injury.
- Anti-Spontaneous Breakage Design: Through homogenization treatment (Heat Soak Test), the glass’s susceptibility to spontaneous breakage caused by nickel sulfide inclusions is reduced to below 0.1%.
Optical and Aesthetic Features
- Symmetrical Aesthetic: The spherical curvature creates a visually harmonious effect, making it ideal for iconic buildings such as observatory domes and spherical exhibition halls.
- Light Focusing/Scattering: Forward Application: The spherical shape can be designed as a focusing lens (e.g., for solar collectors).
  Reverse Application: By using frosted or coated finishes (such as AR coating), glare and distortion can be minimized.
Installation and Functionality
- Self-Supporting Potential: Properly designed spherical structures can reduce reliance on external frames, making them ideal for applications like glass domes.
