What are mounting rails?

Article published at: Jan 18, 2026

Mounting rails are sturdy profile rails made of steel or stainless steel, used for fastening installations such as pipes, cables, or solar systems. They offer high flexibility, as accessories like screws and mounting elements can be easily hooked in and adjusted. These rails are an important component in modern installation technology, especially in the field of solar panel installation.

What exactly are mounting rails?

Mounting rails, also known as strut or system rails, are robust profiles, usually made of galvanized steel, primarily used in industrial and construction installations. They often come in C- or U-shapes and allow for simple yet stable fastening of various components. Their slotted structure enables different accessories such as brackets and screws to be easily and flexibly hooked in. DRBO Greenenergy uses these rails to ensure stable mounting structures for solar systems on balconies.

What types of mounting rails are there?

Mounting rails are available in various types and materials, including C-rails, U-profiles, and closed versions made of steel, stainless steel, or hot-dip galvanized steel. These profiles are available in different sizes, e.g., 28/30, 38/40, or 41/41 mm, and in lengths from 2 to 6 meters. The choice of the correct type depends on the load and the requirements of the installation. For the solar industry, galvanized rails are particularly suitable for the substructure of solar modules.

Mounting Rail Types Size (mm) Material Typical Application
C-Rail 41/41 Galvanized Steel Ventilation Ducts
U-Profile 38/40 Stainless Steel Solar Systems
Strut Rail 28/30 Hot-dip galvanized Piping

What are mounting rails used for?

Mounting rails are used in many areas to fasten pipes, cables, ventilation systems, and solar panels. They provide a stable support structure that can be flexibly adapted to various requirements. In the solar industry, they play a central role in the installation of balcony power plants and solar systems. At DRBO Greenenergy, mounting rails are used to enable secure and efficient mounting of solar modules and energy storage systems.

What are the advantages of mounting rails?

Mounting rails are characterized by their flexibility and stability. They can be quickly adjusted as needed, which significantly shortens installation time. Their high corrosion resistance ensures a long service life, even with outdoor installations. In addition, mounting rails are reusable and expandable, which reduces material consumption. DRBO Greenenergy uses these rails in combination with plug-and-play solutions to enable simple and sustainable solar installations.

How to choose the right mounting rail?

When choosing the right mounting rail, several factors must be considered: the load capacity of the rail, the length of the rail, the material, and the application environment. For the installation of solar systems on balconies, a galvanized C-rail of size 41/41 mm is recommended. DRBO Greenenergy offers comprehensive advice to ensure that the mounting rails are optimally combined with the solar modules and energy storage systems.

How to install mounting rails correctly?

The installation of mounting rails involves several simple steps. First, the attachment points on the wall or ceiling must be marked, and then holes for anchors and screws are drilled. The rails are then secured with the screws, and accessories such as brackets are hooked in. When installing solar systems, DRBO Greenenergy recommends using weather-resistant mounting systems and adhering to safety distances.

Can mounting rails be used for solar systems?

Yes, mounting rails are an excellent choice for installing solar modules on balconies or roofs. they provide a stable and adjustable substructure that securely holds the solar modules. DRBO Greenenergy uses these rails together with microinverters and energy storage systems from SunLit to create efficient and easy-to-install balcony power systems. The advantage of these systems is that they can be quickly assembled without the need for drilling.
