What is 12mm toughened glass cut to size?
12mm toughened glass cut to size is a high-strength, safety glass produced by heating standard float glass to approximately 700°C and then rapidly cooling it (quenching). This tempering process makes the glass 4-5 times stronger than regular annealed glass and ensures that if broken, it shatters into small, blunt pieces rather than sharp shards, reducing injury risks.
Key features of 12mm clear toughened glass:
✔ High Strength – Resists impact, thermal stress, and wind pressure.
✔ Safety Compliance – Meets international safety standards for architectural and interior use.
✔ Custom Sizes – Precisely cut to your required dimensions before tempering.
✔ Optical Clarity – Maintains excellent transparency for a clean, modern look.
✔ Heat Resistance – It withstands higher temperatures than standard glass.
This glass is ideal for applications requiring durability, safety, and a sleek finish, such as glass railings, partitions, shelves, and commercial storefronts.

Why use 12mm toughened glass cut to size for the project?
Choosing 12mm toughened glass cut to size offers several advantages:
1. Enhanced Safety
Unlike regular glass, toughened glass breaks into small, granular pieces, minimizing injury risks—making it perfect for high-traffic areas like shopping malls, offices, and homes.
2. Durability & Impact Resistance
The tempering process strengthens the glass, making it resistant to cracks, scratches, and thermal stress. It’s ideal for exterior facades, shower doors, and balustrades.
3. Customization Flexibility
Being cut to size before tempering, this glass can be tailored to exact project dimensions, reducing waste and ensuring a perfect fit.
4. Aesthetic Appeal
The clear tempered glass 12mm thickness provides a sleek, modern look, enhancing natural light flow in interiors while maintaining privacy when combined with frosted or tinted options.
5. Versatile Applications
- Architectural Glazing (windows, doors, curtain walls)
- Shower Enclosures & Bathroom Partitions
- Glass Railings & Balustrades
- Table Tops & Shelving
- Retail Displays & Storefronts
