K2 – PV mounting systems for solar power

Our mounting systems cover nearly the entire spectrum of possible roofing and some soil class applications. We distinguish between systems for:

  • Corrugated roofing:
    • Sheet metal or rather tin metal
    • Fibre cement
  • Tile roofing:
    • Concrete tiles (Classic, Designer, Prestige)
    • Clay tiles
  • System roofings or standing seam:
    • Klip-Lok or Klip-Tite
    • Round, double, angeled and snaplock standing seam
  • Trapezoidal sheet metal, Trimdek and sandwich panels

K2 Base: Easy planning tool

The SingleRail system planned in K2 Base makes your project planning supereasy. This mounting system is very flexible an can be used for many roofing types.
The design process in K2 Base let's you plan residential projects like a clockwork and big commercial are no obstacle any more. The software creates exact assembly plans and flawless BOMs.

Corrugated sheet metal roofings

The SingleRail PV mounting system is flexible in  use for different roofings. On corrugated tin roofings  a classic L-foot is used as roof attachment. You can add an additional adapter for corrugation which improves the sealing and makes the alignment perfect.



Concrete or clay tiles: SingleHook Vario tile brackets

Our European roof hook experience is fully integrated in our SingleRail system. We use all-waether stainless steel and corrosion-fee aluminium for our tile brackets. They are height adjustable and the brackets can be move side-wise t fit best with any tile.
You can also build with two rail layers to change the module orientation or simply to improve the ventilation and power output of the modules.

Trapezoidal sheet metal

This roofing type is a key application area for us. We developed solutions based on the SingleRail system and fixation in the sub structure but we also offer solutions with fixation in the roofings.
This saves much assembly time and lots of material. These mounting systems are proven worldwide, certified where necessarry and are one of the fastest growing installation methods in this application field.

K2 Base: Easy planning tool

The planning process in K2 Base helps you with perfect placement, proven loads calculation and a flawless BOM. Only five steps are necessary to achieve a built-ready result. Plan big commercial PV systems like clockwork as well as painfree residential project management.

Several little helpers make your project management easy. You can exchange planning data with partners and you can export to other tools for electric wirering or yield planning.

RibClamp for Klip-Lok roofings

We already developed a mounting solution for Klip-Lok roofings which we offer in other parts of the world. Currently we're improving this solution for our Australian product range.


The Rib Clamp system is roof fixion and module support in a single component. The module clamp can be attached directly to it for landscape orientation of modules or you add a second rail layer which makes portrait orientation possible.

PV mounting solutions for flat roofs

We are well known for our single-sided and double-sided flat roof mounting systems for PV plants. They can be used on ply-membrane, concrete, gravel and Bitumen roofings as well as on green roofs.

The planning is a well though design process which ends up in a really easy and flexible assembly.

MultiRail short rail system for tin roofings and Trimdek

This system is a very efficient solution for trapezoidal tin. Short rails with sealing and flexible placement options make it very easy to install.

Not only the installation properties guarantee full satisfaction also the small dimensions and weight make it very flexible in transport. The specialty: Rails are attached directly in the roofing. This makes the whole installation really fast and easy.


It is a proven and tested system which is on the market since years. Suitable for smaller residential projects and real PV plants on commercial roofs.
