Tempered Safety Glass

As a core manufacturing process for tempered glass, Round FE (Front Edge Rounding) is a critical indicator of international quality standards. We strictly comply with EN 12150/ANSI Z97.1 specifications, delivering professional-grade edge safety solutions for global clients.

Why Round FE Matters

✔ Ultimate Safety

Eliminates 90% of edge stress concentration, reducing spontaneous breakage risk

Arc radius ≥0.5mm (exceeds EU basic requirements)

Passes ball drop impact test (1040g steel ball from 2m height)

✔ Ergonomic Design

Smooth touch with zero burrs, ensuring safe installation and maintenance

Perfect compatibility with stainless steel/aluminum framing systems

70% reduction in transport breakage rates

✔ Global Compliance

Mandatory for EU CE Certification (EN 12150 Annex C)

Required by US ASTM C1048 Class 1 safety standard

Essential parameter for GCC certification in the Middle East
