Tradition meets innovation

Lungmuß Feuerfest was founded in 1958 by Hans Lungmuß. It is still a family-run company, now in the third generation. As the owners are closely involved in managing the business, quick decision making and high flexibility are guaranteed.

Starting from the initial plant in the Dortmund harbour area the production has been continuously expanded. A second production plant was established nearby in 1971. Here, most of the refractory products are manufactured. The fabrication of prefabricated parts started in 2007. Since 2015, after a large plant extension, this production line carries on in a new production plant with a significantly increased capacity.

From a strong local orientation at the beginning of its existence, Lungmuß Feuerfest has now developed into a global supplier. Although the export share is more than 50 %, the German market is still the basis for technical enhancements.

Von einer stark lokalen Ausrichtung zu Beginn des Bestehens ist Lungmuß Feuerfest zu einem weltweit operierenden Anbieter geworden. Der Exportanteil liegt bei über 50%, wobei der deutsche Markt nach wie vor die Grundlage für die technischen Weiterentwicklungen bildet.
