About Carl C. A/S

Carl C. A/S was founded in 1969, and over the years has accumulated vast experience and expertise in manufacturing steel towers, foundation systems and accessories for the above.

The company supplies towers to a wide variety of industries where quality and safety are top priorities. For this reason, our primary products include:

  • Telecommunication towers, such as lattice towers, tubular towers, flagpoles and false chimneys.
  • Meteorological towers such as self supporting towers, guy-wire towers for wind measurements. Onshore and offshore.
  • High-voltage towers and steel structures for high-voltage sub-stations.
  • Floodlight towers for illuminating public areas, roads and streets.
  • Overhead gantry signs for traffic information.
  • Telescopic towers for various applications.
  • Towers for small wind turbines.





Carl C. A/S has always been renowned for its high-quality products.

To continue to ensure high quality, Carl C. A/S is certified to the quality-management system DS EN ISO 9001. In addition, the company is certified to DS EN ISO 3834-2 and DS EN ISO 1090 EXC 1–4, which means that Carl C. A/S meets the requirements for being able to manufacture and CE-mark steel structures in accordance with the most stringent requirements in Europe.

The combination of these systems guarantees our customers that Carl C. A/S delivers products which meet the specified and statutory requirements.

The systems also ensure that Carl C. A/S has qualified staff with knowledge and training for planning, carrying out and controlling the manufacture of our products.

Welding inspection is carried out by internal and external staff alike. The inspection always concludes with a report.

Data from all processes is collected and documented in a comprehensive quality-documentation process.



Carl C. A/S has developed a wide range of products. These include our self supporting lattice towers as standard solutions, which are available in heights of up to 140 m and can be equipped with ladders, fall arrest devices, booms, and head frames in accordance with IEC 61400-12-1 etc.

Carl C. A/S performs the structural calculation of towers in-house, or collaborates with recognised external engineers with years of experience in the field of structural tower calculation for offshore and onshore environment.

Our towers are always individually calculated for each task in accordance with Eurocode standards. Requirements from IEC standards are often used, as these are particularly important for calculations involving meteorological towers.

For many years we have also gained massive experience in structural calculation of towers for demanding environments, such as extremely low temperatures, strong winds, ice thickness and dynamically impacted structures subject to fatigue in offshore environment.


Carl C. A/S has more than 8.000 m² of factory space at its disposal,
and an outdoor storage area covering 17.000 m².
Our workforce consists of around 45 employees.
