MicroRail System

The MicroRail System is a mounting system for corrugated and trapezoidal sheet metal roofs. The short rail system including sealing is fixed directly into the roof covering without additional parts with self-tapping sealing screws. The PV modules are mounted in landscape orientation.
The rail channel is designed for the universal MiniClamp module clamp and is therefore suitable for most module frame heights. In addition module frame grounding can be very easily established using the Terragrif K2MI for the MiniClamp.

  • No fastening in the purlins, therefore fewer roof parameters have to be determined
  • Quick and easy mounting on corrugated sheet metal using an adapter and directly on trapezoidal sheet metal
  • Only two rail lengths for all load cases

One system for two types of roofing

With corrugated sheet roofs, pre-drilling and time-consuming fixing in the roof substructure is no longer necessary.This makes the roof connection of PV systems on corrugated sheet metal roofing just as quick and easy as with our well-known trapezoidal sheet metal systems.

 

The MicroRail uses the same module clamps as the Dome systems. This means that all commercial roofs can be realized with one type of clamp. For corrugated iron roofs the MicroRail is used as a set with the CSM adapter. Without the corrugated sheet metal adapter it can be installed directly on the trapezoidal sheet metal – just like our MultiRail system.

Roof connection and module mounting rail

It couldn't be simpler. The two MicroRail mounting rails are equipped with an EPDM seal at the bottom. They are fixed in the pre-drilled screw holes with self-tapping sealing screws directly in the roofing.

 

Then only the module clamp is missing and the module assembly can begin. Depending on the wind load case, the longer MicroRail 25 is used, which is fixed with four screws.

Compatible corrugated sheets

The MicroRail System has a wide range of applications for corrugated sheets. The CSM adapter is suitable for radiuses between 22 - 45 mm.

 

This covers the most common profile types worldwide and the system is the solution for short-term, cost-sensitive projects due to its low transport requirements.

Small component dimensions and low weight

The speed of PV expansion and the need for solutions that can be implemented in the short term has increased. The MicroRail System fully meets these requirements.

 

All components have compact dimensions with small packaging volumes. In addition, the total weight is low overall due to the short rail lengths. This system is ideal for fast and flexible transport to any place in the world.
