Multilayer protected 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) 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), 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 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.


The cover element ensures the following performance requirements:
