S:FLEX mounting systems for trapezoidal and corrugated sheet metal roofs and roofing sheets
On corrugated and trapezoidal sheet metal roofing and roofing sheets, installing photovoltaic systems on the S:FLEX sloping-roof frame not only safely anchors the system, it also ensures optimum protection of the roof membrane, flexible configuration options and maximum cost efficiency.
Thanks to our wide range of different systems, we have the right installation option for almost every pitched roof as well as for slightly inclined roofs:
