Flanges & corners
Our Air Duct Solutions division plays a central role and is specialised in the development and production of slip-on flanges for rectangular air ducts. The portfolio is complemented by matching corners that enable high-quality production and installation of air duct systems. With a wide range of systems and designs, we offer our customers customised solutions for the most diverse requirements in modern ventilation technology.
Stability and precision
Slip-on flanges are the backbone of rectangular air duct systems and provide the necessary stability and functionality that are essential for efficient air circulation. Our Air Duct Solutions division develops and manufactures these flanges with the highest precision to meet the requirements of manufacturing companies and installers alike.
Variety in systems and designs
We offer a variety of air duct profiles to suit the specific requirements of different projects. The most important features include:
- Different material thicknesses to suit different requirements.
- Corrosion protection through galvanised or coated surfaces that ensure the longevity of the air ducts.
Thanks to this variety of designs, our slip-on flanges offer the perfect solution for every application - from simple standard projects to complex large-scale systems.

For high-quality production
In addition to the slip-on flanges, corners are a crucial component in the production of rectangular air ducts. These corners not only ensure a precise connection of the profiles, but also contribute significantly to the stability and tightness of the entire system.
- High accuracy of fit: The corners are precisely matched to the slip-on flanges, making installation quick and easy.
- Robust construction: Manufactured from high-quality materials, the corners guarantee a high load-bearing capacity and durability.
- Easy handling: The sophisticated design reduces installation times and simplifies installation even in demanding environments.
- Flexible designs: Various sizes and shapes are available to meet the requirements of different air duct systems.
