short rail

the solution for trapezoid shield roofs
at an angle of up to 40°

schnelle Montage

fast mounting

entwickelt im Windkanal

developed in a wind tunnel

Ultraleicht und nahezu ballastierungsfrei

ultra lightweight with a minimum of ballast needed

Minimum material input for maximum yields

short rail features top-level flexibility: the substructure can be installed both along and against the trapezoidal orientation, comfortably compensation specific roof conditions. Our system is suitable for all standard trapezoidal metal shields with an easy and fast application regarding only two tools. Our extra benefit for you: We provide screws with drill bits making the mounting of our substructure free from metal chips and for that reason completely clean.

Advantages for you:

  • developed and aerodynamically optimised in a wind tunnel
  • suitable for roofs with a limited load-bearing capacity
  • preconfigured: EPDM layer glued to the bottom side
  • short rail is resistant to UV, wind and corrosion
  • quick installation saves time and money: no other mounting system on the market can be installed faster
  • minimum shipping and storage costs thanks to the small scale of the product: 750 kWp of our short rail measure 0.9 x 0.9 metre in packaging
  • rooftop impermeability is not affected by our product in any case, thanks to the integrated building protection mats
