K2 – Mounting systems for solar power

Our mounting systems cover nearly the entire spectrum of possible roofing and soil classes. We distinguish between systems for tiles, corrugated fibre cement, trapezoidal sheet metal, standing seams, or flat roofs. We offer tailored solutions for open-site systems.

We are delighted to create individual plans for projects that our standard products do not accommodate.
