About us

Westfälische Drahtindustrie GmbH can trace their company origins to a works for wire fabrication founded in the year 1856, which was operated as an incorporated firm (AG) as early as in the year 1872 and from 1890 under the present name WDI.

For more than 150 years the company has occupied an important position in Germany, as well as internationally, in the wire industry. Following a group merger (Krupp/Kloeckner) in the meantime, the company has been active on the market since 1st October 1987, again under the company name Westfälische Drahtindustrie GmbH.

Today Westfälische Drahtindustrie GmbH, with company headquarters in Hamm, is the largest group-free wire producer in Europe.

News & Innovations

The new cold forming wire developed by WDI and ArcelorMittal in accordance with EN10263-4:2018 is a modern alternative to conventional wire and has low strength and high ductility.The basis for drawn wires is wire rod with the mechanical properties of approx. 500 MPa (20MnB3) - 520 MPa (20/23MnB4), which enables the customer to achieve a sustained reduction in costs, e.g. by eliminating the need for wire rod annealing (+AC).
