Knauf Interfer Benelux

The sales office for Benelux, Great Britain and Ireland

Interfer Staal in Eindhoven - part of the Knauf Interfer Group since 1992 - became Knauf Interfer Benelux.

Our customers in the Netherlands, Belgium, Luxembourg, Great Britain and Ireland receive competent technical advice and full access to our extensive range of steel products, from sheet metal to long products in many different grades and dimensions, at the Eindhoven sales office. Since 01.11.2020 the sales office has not only had a new name! The biggest change for the Benelux team is the now complete access to all steel products of the Knauf Interfer Group and the complete integration into the internal systems as well as the accessibility to the logistics. The existing product range has been extended considerably.

Product and performance range:

- NEW Cold rolled strip
- NEW Slit Strip, Coils, Sheets and Blanks
