K2 PV mounting systems with hanger bolts or solar fasteners are suitable for corrugated sheet metal roofings. With the MicroRail System it is also possible to fix directly in the corrugated sheet without drilling in the substructure. The mounting rail families SingleRail and SolidRail are the solution with fixation in the substructure of the roof.
