● The sheet has a corrugated profile made in co-extrusion
● Its lightness allows the use of load-bearing structures that are not particularly reinforced
● The sheet is light, easy to transport and install, resistant to fire, impacts, resistant to agents chemical or atmospheric and equipped with high acoustic and thermal insulation.
● The model has a wide range of roof accessories that allow customization of the installation
● The model has a universal ridge that allows the connection between two opposing pitches of the roof
