Specification
Coverib 850 Multilayer metal sheet with trapezoidal profile, CE marked according to UNI EN 14782. Appendix A: complies with UNI EN 508-1 Appendix B: consisting of a structural galvanized steel sheet (EN 10346) with a thickness of 0,60 mm (ie mm 0,50 or 0,80) protected in the upper face by an anticorrosive and soundproofing thermoplastic coating (about 1.5 mm thick) and by a natural aluminum foil (or pre-painted aluminum, or electrolytic copper), and in the lower face by a primer and a natural aluminum foil (or prepainted aluminum).
The external layers wrap the side edges of the sheets along the entire length to guarantee their full protection. To ensure the characteristics stability P= 300 performances over time, the protection with anticorrosive and soundproofing function, has a thickness of about 1.5 mm and it is positioned on the extrados of the sheet.
