Since 2007, we have completed the electrical installation of more than 150 stores in Germany, Croatia, Slovenia and Hungary.Our group of companies is responsible for the complete electrical installation of the stores of one of the leading drugstore chains in 4 countries.
Our group has entered a huge evolutionary process when we entered the international market thanks to this customer. This shows that we have been able to deliver a quality of service that has met the needs of international companies.
It has given our employees the opportunity to work abroad, where they can gain experience that is very rare in the market and their professional skills can be improved.

World leading car manufacturers
Our group of companies carries out electrical engineering work in 2 countries for the leading car manufacturers in Hungary and Germany.
One of the projects I am most proud of. It was the next big development for the group in the international market. In addition to the Group, the employees have also been given a very good opportunity to develop their professional skills to the quality required in Germany. This project is also a great development opportunity for our employees, because they often have to apply a different, new technolody to projects.

Buildings of market leaders
Our group carries out electrical work in the facilities of major companies in 2 countries. We have carried out numerous projects in Hungary and Germany.
We are involved in the construction of factories for major companies. An interesting experience for me was when we had the opportunity to carry out the electrical installation of the factory of the largest manufacturer of airport conveyor rollers on the market. It was a challenge to finish on time, but of course we met the customer’s expectations.
