LOMA Headquarters


LOMA is firmly anchored in southwestern Germany and has customers in all of Europe’s major markets. From our locations in Germany and Poland we are ideally situated to reach the important business centers and LOMA customers throughout Europe.

Our location in Koenigsheim, Germany
Koenigsheim, Germany is an idyllic corner of the highest plateau in the Swabian Alb in southern Germany’s dynamic industrial region. Peacefulness, quality of life and cutting-edge technology are not mutually exclusive. In fact, they go well together – in particular at LOMA. Our highly motivated and extremely skilled employees are the backbone of our success.
Our location in Ruda Slaska, Poland
Our location in Poland is near Katowice and is a short 15 minutes to the freeway entrance toward Germany and 25 minutes to the Katowice airport. This area has historically been regarded as industrially well-developed. Because of this, our Poland location offers our most important asset: our well-trained and experienced employees.
