Pitched roof structures - comprehensive solutions for professionals

Pitched roof structures are a key element of photovoltaic and solar installations.   At Onninen we offer a wide range of high-quality components. Our products provide stable and durable mounting of panels on various types of roofing. We care about the safety and efficiency of each installation.

Our range includes all the necessary assembly elements. We offer adapters, edge covers and structural connectors. End and middle clamps for mounting panels are also available. The offer is complemented by cable clips and cable ties for organizing cables.

Key components of a pitched roof structure

The system is based on aluminum profiles and angles. They provide a solid base for the entire structure. They are fastened with double-threaded and Allen screws.   The safety of the installation is guaranteed by chemical anchors and expansion bolts.   We also offer mixers for the correct application of anchors.

It is worth paying attention to spacer feet and roof bridges. These elements allow for precise leveling of the structure. Rubber plates protect the roof covering from damage. Fastening screws and flange nuts are used for the final assembly of the panels.

• Aluminum profiles and angles - construction base
• Chemical anchors and dowels - solid fixing
• Clamps and screws - secure panel mounting
• Cable accessories - tidying up the installation

Selecting a structure for a pitched roof - key criteria

The correct selection of structural elements is of great importance for the durability of the installation.   In our daily practice, we see how important an individual approach is. The angle of the roof is the first parameter to be considered. It influences the selection of appropriate brackets and angle brackets.

The type of roof covering is another key factor. We use different solutions for ceramic roof tiles and different ones for metal roof tiles. The roof covering material determines the choice of anchors and fastening screws. Corrosion resistance is also important in the case of coastal installations.

Snow and wind load are parameters that affect the strength of the structure. In mountainous regions, we use reinforced profiles and additional supports. Wind zones require the use of special protection. Our experience allows us to select optimal solutions.

The layout and weight of the photovoltaic panels are other important factors. They determine the number and spacing of the mounting points. Stronger clamps and profiles are necessary for heavier modules. We also take into account future service work when selecting the structure.
