Trapezoidal sheet metal roofs are indispensable on agricultural and industrial buildings – such as barns, warehouses or production facilities – due to their robustness, durability, and versatility. However, for the installation of photovoltaic systems, they place special demands on planning and installation. With its proven Dome 6 components, K2 Systems offers two clever solutions for the additional elevation of PV modules on trapezoidal sheet metal roofs. Both variants have been tested in practice and can now be planned directly by PV professionals using the K2 Base design software – for more efficiency and flexibility in project planning.
The additional elevation on trapezoidal sheet metal roofs enables a better beam angle and thus an optimized energy yield – especially with flat roof pitches between 0° and 10°. Depending on the roof type and the desired module orientation, two proven system combinations – based on short or long rails – allow for precise and yield-optimized installation of PV modules.
S-/D-Dome 6 on K2 BasicRail
The K2 BasicRail is a true all-rounder: it can be installed in just four steps, support high loads and is certified with a German building approval. On trapezoidal roofs, it is mounted as a support rail at right angles to the high crest and is mounted floating, which ensures controlled thermal expansion.
The rail is fastened using the K2 BasicClip, a mounting bracket with an insertion function, which is fixed directly to the sheet metal with self-tapping screws. The Dome 6 components known from flat roof applications are used for the elevation, so that the solar panels are finally rotated by 90° to the roof pitch. This ensures optimal solar exposure. Depending on the project requirements, this solution can be implemented with either the S-/D-Dome 6.10 or the S-Dome 6.15.
S-Dome 6.10 on K2 MultiRail
The K2 MultiRail short-rail system is particularly optimised for material and transport efficiency. With just one component, it combines roof attachment and mounting rail in a single product. This solid base rail is available in various lengths. When mounted on trapezoidal sheet metal, the rail is installed parallel to the high crest, allowing the modules to be aligned along the roof slope. This variant, in combination with the S-Dome 6.10, offers a stable and yield-optimized solution.
Now digitally plannable – with K2 Base
What previously required support from the K2 team can now be planned independently: Both variants for elevation on trapezoidal sheet metal roofs are available in the K2 Base design software.
The intuitive user interface enables fast, precise and secure planning, including structural analysis and item list. For individual project requirements, K2’s technical support remains available – especially when alternative parallel mounting variants are needed, for which the modular K2 Systems product range offers further solutions.
