Our story

Our history begins on the 1st of April 1925 with the ground-breaking ceremony and the establishment of the company Karl Woelm + Sohn KWS Baubeschläge by Karl Woelm Sr. and his son Karl Jr. at the Hasselbeck site in Heiligenhaus. Seven years later, in 1932, the company Hespe und Woelm, HELM for short, was founded by Wilhelm Hespe and Ernst Woelm.

While KWS has made its mark in the field of architectural hardware with door handles and door holders, HELM became renowned as a pioneer in the field of sliding technology. The companies are not only connected by their shared location in Heiligenhaus but also by family ties: Ernst Woelm is the brother of Karl Woelm Jr. With time, the both of the companies prosper, the manufacturing plants expanded, more and more employees are recruited and loyal clientele are formed.

In 2005 the companies KWS and HELM merged to become Woelm GmbH. With this, two companies which had long been close to each other merge. The two established brands are preserved under the umbrella of Woelm GmbH.

Our philosophy

In order to be able to offer high quality and innovative system solutions today and in the future, we are continuously expanding and optimising our product range. As a family-owned company, we have made our goal to be a reliable and sustainable business partner. Therefore, the satisfaction of our customers and partners takes precedence above all else, which is guaranteed by our outstanding quality, continuous improvement and excellent service.

We know – whether architectural hardware or conveyor technology: every building project is unique. For this reason, in addition to the tried and tested applications and expert advice, we also offer individually customised solutions that are designed and produced in tandem with the customer. In the process, our customers benefit from our many years of experience and the know-how acquired from numerous national and international projects during consultation, planning and implementation.

At our headquarters in Heiligenhaus, we bring together all production steps: from pressing, casting, machining and welding all the way to surface technology, final assembly and logistics, hence, taking control of every aspect of the processes. With this, our products bear the "Made in Germany" seal of quality. In order to maintain our high quality standards, we work with reliable and long-standing partners across our entire supply chain, many of whom come from our regional network known as the Schlüsselregion (Key Region).

Our products meet the highest standards: We not only test this regularly in our own test laboratories, but also at reputable institutes such as ift Rosenheim, TÜV or DEKRA.
