Welcome to Walter Lumberg

GmbH & Co. KG

We are a manufacturer of washers in a variety of materials and manufacture them at our Plettenberg / NRW location. What began in 1922 in the smallest of a company founded by Walter Lumberg is accomplished today with more than 30 employees in an area of approximately 7,500 sqm. We continue to be an owner - managed, independent family business in the 3rd. generation.

In addition to the classic washer, we also have sealing rings and stamping parts according to drawing in the assortment, whose tools we construct and manufacture in our In-house tool manufacture.

Traditionally, we manufacture parts made of steel, but our high-performance production process also includes parts made of brass, copper and aluminium. Other materials, e.g. in the high-strength stainless steel ranging from HV 200, are also available on request.

Our products are used in the classic screw wholesaler with integrated C-parts management and especially in fastening technology. There are also many customers in the DIY sector or in the sanitary and installation industry. In the past few years, we have been increasingly producing accessories for the commercial vehicle and agricultural machinery industries as well as for green technology.
