Corrugated and ribbed polycarbonate |
 |
|
With their very high shock-resistance and the 98% elimination of harmful UV rays, corrugated and ribbed polycarbonate sheets can be adapted to all roof glazing projects thanks to their special structure.
Its endurance and resistance to bad weather is impressive: in simulation tests, not even 20mm-diameter hailstones hitting the glass at 21m/s can shatter the sheet.
Despite these high resistance properties, corrugated and ribbed polycarbonate plaques remain relatively light with good optical properties.
USES:
- Industrial roofing glass
- Covered passageways
- Safety glass
