Photovoltaic mounting on pitched trapezoidal sheet metal roof

The CHRONOS Trapez mounting system is used for mounting a photovoltaic system on pitched roofs with all types of trapezoidal sheet metal roofing (minimum thickness of steel: 0.5 mm; minimum thickness of aluminum 0.6 mm; minimum width of the high bead 15 mm). The modules are installed parallel to the roof – the modules can be installed both vertically (upright) and horizontally (horizontally). The mounting system is designed either with 120 mm long CHRONOS trapezoidal sheet metal short pieces in the raised bead course or with 267 mm long (87 – 207 mm raised bead spacing) or 393 mm long (213 – 333 mm raised bead spacing) short pieces at right angles to the raised bead course. The universally pre-punched short pieces enable flexible and at the same time extremely fast and thus cost-effective assembly of the modules. The assembly is implemented by screwing using self-tapping thin sheet metal screws approved by the building authorities. To ensure stability, a project-specific wind suction calculation supplements the mounting system.
