Target-oriented and innovative

Founded in 1970 on the former site of the closed wood wool factory SINGER by Günther and Florentine Grabmayr, the company quickly developed into a competent and high-performing partner specializing in the construction of high-voltage pylons and substations. Since its beginning, the company has been located at Hohenberg / Lower Austria, which is a sign of constancy and consistency.

Our business has always been based on the principle of trust between customer and contractor. This philosophy is firmly anchored in our corporate culture and is upheld by our employees. Adherence to delivery dates, co-operation in partnership and a culture of discussion with our customers, suppliers and partners - this is what has characterized Stahlbau Grabmayr for more than 50 years.

Now the successor generation offers future-oriented, creative and flexible solutions for all your requests. With an adequately lean management structure and a stable network of partners we are moving towards an exciting future.
