The company develops and produces cable management systems for use in buildings, industrial facilities, and infrastructure projects.
History
Niedax was founded in Berlin in 1920 by engineers Alexander Niedergesäß and Fritz Axthelm as Niedergesäß & Co. OHG. The company initially manufactured fastening materials for the electrical industry.
After World War II, the company was rebuilt and opened a branch in Linz am Rhein. A hot-dip galvanising facility began operations in St. Katharinen in 1975. By the end of the 1970s, production had been relocated to St. Katharinen, while the company's administration remained in Linz am Rhein. In 1995, Bruno Reufels and Egon Winggen took over the company's management from Franz Kolmer following his retirement.
From 1995 onwards, Niedax began expanding its international operations. The company acquired Elektraplan in 1996 and the Dutch firm Alinco in 1999. On 1 January 2000, it took over the Kleinhuis Group, based in Lüdenscheid, followed by Rico GmbH & Co. KG in 2004. Most of the larger acquisitions were made during periods of economic crisis, particularly the 2008 financial crisis and the COVID-19 pandemic. During this time, Niedax also bought two steel service centres.
Egon Winggen retired in 2007 and was succeeded by Alexander Horn, who joined Bruno Reufels as managing director.
A new operational management team took up its duties on 1 January 2023. Since the summer of 2023, the Niedax Group has been purchasing CO2-reduced steel from various suppliers and processed the material at its own production facilities.
In 2024, Niedax took over the Spina Group, an Italian manufacturer of cable management systems and distributor of electrotechnical materials for industrial facilities. In November 2024, Niedax and ABB established the joint venture Abnex Inc., which brings together the two companies' North American cable tray businesses.
In 2025, Niedax opened a new site in Rahms, which primarily houses administrative and sales functions as well as a newly built technology campus. Since its completion, the site has served as the coordination centre for the group's European infrastructure projects. Niedax Infrastruktur GmbH was established in connection with the development.
In 2026, Niedax started working on a fibre-optic network for critical infrastructure in Germany. In April 2026, the Niedax subsidiary Netz33 GmbH began to work on a roughly 130-kilometre test route in Niedergörsdorf, Brandenburg. Along this route, Netz33 is testing technologies for the protection of data connections against sabotage, disruptions, and other security risks.
Corporate structure
Niedax Holding GmbH, based in Linz am Rhein, serves as the parent company of the Niedax Group and has remained entirely family-owned since it was founded.
The group is organised in several corporate levels. Niedax Verwaltungs GmbH sits below the parent company and manages Niedax Beteiligungs GmbH & Co. KG. This company, in turn, holds a stake in Niedax GmbH & Co. KG, which consolidates most of the group's shareholdings.
Niedax has 81 locations in more than 30 countries, including 25 production facilities. The group operates joint ventures with the Italian companies FEMI-CZ and Steelline, R&M Electrical Group in Southampton, United Kingdom, and ABB in North America. As of September 2023, the group had around 2,700 employees. The group consists of 68 directly or indirectly owned subsidiaries across Europe, North America, Asia, and the Middle East.
Business areas
The Niedax Group is active in the production and distribution of cable management systems as well as electrotechnical installation and fastening materials made from metal, PVC, and glass fibre. The systems are used in industrial facilities, office buildings, and infrastructure projects.
A number of subsidiaries operate in the steel service sector, where they process steel for external industrial customers and for the group's own cable tray manufacturing.
The distribution business covers international trading in electrotechnical products together with services including planning and installation.
Infrastructure represents a further area of activity and includes the construction of data centres and the expansion of general network infrastructure.
