12mm Tempered Safety Glass for Pool Fencing - China Suppliers & Factory Direct Sales

Superior Safety

Tempered glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. When broken, it shatters into small granular chunks instead of splintering into jagged shards, making it safer for use in various applications.

Pre-Tempering Fabrication:

• Cutting: Sheets are cut to exact required dimensions beforehand.
• Edging: Edges are ground and polished. Frameless glass features 3mm-5mm rounded corners to avoid scratching.
• Drilling/Notching: All holes and cut-outs must be processed prior to tempering.
• Washing: Sheets are thoroughly washed with de-ionized water.

Thermal Stability

Tempered glass exhibits remarkable thermal stability, capable of withstanding temperature fluctuations ranging from 250 to 320°C. In contrast, ordinary annealed glass can only tolerate temperature changes between 20 and 100°C.

Tempering Process:

• Heating: Heated to 620°C to 700°C inside a carefully controlled furnace.
• Quenching: Rapidly cooled by high-pressure air blasts on both surfaces.
• Stress Creation: Outer layers lock in compression while the interior remains in tension, increasing strength.

Materials: High-quality float glass (clear, low-iron, tinted, or coated), air, and de-ionized water.

Superior Strength

Four to five times more robust than the same thickness of annealed glass. Higher resistance to impact, mechanical stress, thermal stress, and bending.

Breakdown Safety

Designed to break into tiny, blunt, pebble-like bits instead of sharp shards, greatly lowering the chance of injury.

Thermal Resistance

Tolerates temperature differentials up to 200°C to 300°C without breaking, ideal for fluctuating environments.
