At the plants in Dortmund, Lungmuß Feuerfest develops and produces monolithic refractory materials for the iron and steel production, the non-ferrous industry and foundries. The company uses its flexible corporate structure to ensure innovative developments with customer-specific adaption of the mixtures. Fast decision making processes and the close contact with the customers result in short response times. This process is stipulated in detail in the company-internal quality management system and since 1992 DIN EN ISO 9001, certified by Lloyd’s Register Quality Assurance.

Furthermore, since 2007 Lungmuß Feuerfest designs, casts and dries prefabricated parts for its customers. This division is also part of the certified quality management system.

All raw materials and products are subject to a specified inspection plan which ensures the consistent high quality of the materials used and the resulting products. The required analyses are carried out in the company operated laboratory in Dortmund.

In 2009, the certification of the quality management system according to the DIN EN ISO 9001:2008 requirements took place. The readjustment to DIN EN ISO 9001:2015 was successful established in 2017.

Furthermore, in 2015 Lungmuß Feuerfest has introduced a safety management system in accordance with the standard SCC-certificate. This system corresponds to the rules set out in the “Safety Checklist for Contractors” (SCC), 2011 revision, and is valid for the refractory services in the customer’s plants. This ensures the quality of the service.
