What is 12mm Clear Tempered Glass 40 x 46?
12mm Clear Tempered Glass 40 x 46 refers to high-strength safety glass panels measuring 40 inches (1016mm) wide × 46 inches (1168mm) high, with a thickness of 12mm. This glass undergoes a thermal tempering process, heating it to approximately 700°C followed by rapid cooling (quenching), making it 4-5 times stronger than 12mm standard annealed glass.
Key Benefits of 12mm Clear Tempered Glass 40 x 46:
✔ Enhanced Safety – Breaks into small, blunt granules instead of sharp shards (meets EN 12150 & ASTM C1048 standards).
✔ Superior Strength – Resists impact, wind pressure, and thermal stress.
✔ Crystal-Clear Transparency – Maintains 90% light transmission for unobstructed views.
✔ Weather & UV Resistant – Suitable for both indoor and outdoor applications.
✔ Customizable – Available in different edge finishes (polished, seamed, or flat).
Ideal for glass railings, fences, balconies, and balustrades, this dimension offers a perfect balance of stability and aesthetics.
Why the 40×46 Dimension is a Good Option for the 12mm Tempered Glass Fence Solution?
The 40×46-inch (1016×1168mm) size is widely preferred for 12mm hardened glass railing systems due to several advantages:
1. Optimal Structural Stability
- The 12mm thickness glass panels provides rigidity, preventing excessive flexing in railing applications.
- The 40-inch width ensures secure mounting between posts without sagging.
2. Cost-Effective Installation
- Standardized sizing reduces fabrication waste and speeds up installation.
- Fewer support brackets are needed compared to larger panels, lowering project costs.
3. Aesthetic Versatility
- Clean, frameless designs enhance modern architecture.
- Compatible with clamp-based, stand-off, or channel-fixed railing systems.
4. Safety Compliance
- Meets building codes for railing height (42-48 inches standard).
- Tempered glass ensures fall protection for balconies and staircases.
5. Ease of Handling & Transport
- Lighter than thicker glass (e.g., 15mm or 19mm), reducing shipping costs.
- Easier to maneuver during installation compared to oversized panels.
