RATH: 130 years of experience

Our history


The RATH Group is an international company that is one of the most recognized refractory technology specialists with a comprehensive range of refractory products.


The company operates worldwide today, but this was not always the case. Starting with the acquisition of a porcelain factory in Krummnussbaum in 1891, the family business developed into an internationally active company for the production of refractory bricks and mortars.

In the middle of the 19th century, household products made of ceramics were still produced in Krummnussbaum, where the Austrian production site is still located today. RATH started with the production of tiles and fireclay bricks. In the 1970s, the focus gradually shifted to industrial products, and with increasing internationalization, a group was developed that now consists of seven production sites and more than 550 employees in Europe and the USA, as well as sales representatives in many countries worldwide.
