Our top systems for commercial rooftops

K2 mounting systems for flat roofs are suitable for many surfces such as concrete, bitumen, foil, green roofs, gravel, and trapezoidal sheet metal. Both single-sided and double-sided installations are possible. Installation angles range from 0 to 45°.

Flat roofs

K2 Dome 6 System

The most flexible and versatile system group of the K2 flat roof systems, ballasted according to the latest wind tunnel standards.

K2 Dome Zero System

Our roof-parallel mounting system with a very low construction height is suitable for roof inclinations of up to 10° with common flat roofing coverings.

Trapezoidal/corrugated metal roofs

K2 MultiRail System

The MultiRail System enables direct fastening of short rails to the roof covering with thread-cutting screws.

K2 BasicRail System

The K2 BasicRail System impresses with its quick installation as well as its suitability for high load cases. It is a floating long-rail system with controlled thermal linear expansion, making it especially roof-friendly.

K2 MiniRail System

This short-rail system allows for quick and easy installation for both portrait and landscape orientations. Due to its low weight, significant savings can be achieved in material and transportation costs.

The Challenge

How do you design and install a PV system that optimizes the solar energy output for 55,160 sq m for an industrial rooftop economically, safely, and with minimal complexity?

With the double-sided K2 D-Dome 6 Xpress system – developed for speed and reliability. Pre-assembled components and a click mechanism simplify the installation, significantly reducing on-site time.

The Solution in Action

By leveraging our proprietary digital tools and intelligent interfaces, we designed a system to deliver optimal PV performance with fast, reliable large-scale deployment. All Dome 6 systems have the General Building Authority Approval (abZ) No. Z-14.4-916, and K2 Systems is certified by DEKRA according to ISO 9001:2015 – ensuring proven, long-term quality
