The story

The history of the family Zapp goes back to 1701, when Hermann Zapp, father of Engelberth Zapp, started a steel production north of Ründeroth in the valley of Leppe. He bought an iron hammer and registered a trade.

In 1852 he built his first puddle furnace for steel of constant quality. Steel was produced there for five generations. Also Krupp bought refined steel from Zapp. When in 1857 the Great Depression caught Zapp in a financial imbalance, the company was sold. However, they remained true to steel.

In 1869 Robert Zapp left Ründeroth and founded the steel trading company Zapp (today: Zapp AG) in Düsseldorf in 1871, concentrating in particular on the Europe-wide distribution of English special steels. Zapp had previously studied iron metallurgy and the Bessemer process in England and now used his know-how for the production of special steel. But the new steel grades needed explanation. The competitive advantages that resulted from this required intensive cooperation with the toolmakers.

In the course of time the assortment became ever broader. From 1913 the sales organization introduced the new Krupp steel Nirosta, from 1927 the new carbide Widia.

In 1926 the company Robert Zapp took over the Ergste steelworks, which had specialized in cold forming of stainless steel. For 70 years, the two companies operated largely independently of each other. In the post-war period, the Robert Zapp trading house concentrated on innovative high-performance materials and expanded its branch network. In contrast, the Ergste steelworks increasingly shifted its production to high-alloy and new special steels and expanded its special position among drawing and cold rolling mills. In the 1960s it was decided to concentrate entirely on stainless, acid and heat-resistant steels.

In 1991, the Ergste steelworks bought the Westig steelworks in Unna. In 1995, the two companies merged to form Stahlwerk Ergste Westig. In the following years, production plants in the US in Summerville (South Carolina) and Dartmouth (Massachusetts), the second most important market after Europe.

In 1998, the companies of the group were merged into a family controlled joint-stock company. Since then, the company has expanded primarily in the US, Germany and China. In Germany, the companies Ferd. Wagner GmbH in Pforzheim and [Euro Titan Handels GmbH] in Ratingen were taken over by the Zapp Group and Zapp Precision Metals (Taicang) Co. was founded in China. In the US, the Zapp Group also grew through acquisitions.

As a further step towards a uniform international market presence, Zapp Medical Alloys GmbH and Ferd. Wagner GmbH were merged into Stahlwerk Ergste Westig GmbH in 2013.

In addition, Stahlwerk Ergste Westig GmbH was renamed Zapp Precision Metals GmbH to better express its core business as a niche supplier of precision products internationally. At the same time, Robert Zapp Werkstofftechnik was renamed Zapp Materials Engineering and Robert Zapp Service-GmbH was renamed Zapp Systems GmbH.

In 2018, it became known that the Zapp Group had acquired the Sandvik Stainless Wire business from Sandvik.
