Delachaux

What Delachaux does

Delachaux is a French family-owned industrial group founded in 1902 by Clarence Delachaux and headquartered in Colombes, France, operating through four global business units: Pandrol (rail infrastructure fastening, aluminothermic welding, electrification, and track monitoring equipment), Conductix-Wampfler (energy and data management systems for mobile industrial equipment including cranes, mining, intralogistics, and automotive), DCX Chrome (high-purity chromium metal produced via aluminothermic process for aerospace and energy superalloys), and Lenoir-Mec (magnetic separation, purification, and industrial lifting solutions). The Group employs approximately 4,100 people across roughly 80 sites in 34 countries, with Pandrol serving about 50% of the world's rail infrastructure, Conductix-Wampfler serving roughly two-thirds of the world's seaports, and DCX Chrome's chromium metal embedded in approximately 50% of aircraft engines in flight.

The Group's underlying technologies are physical-engineering rather than digital: aluminothermic rail welding and chromium reduction, rail fastening mechanics, conductor rail and slip-ring energy transmission systems, and industrial magnetic separation. Products are engineered for safety-critical, long-lifecycle applications where qualification cycles and standards create high switching costs. Revenue is generated primarily through direct enterprise sales of hardware and engineered systems to rail network operators, port operators, aerospace manufacturers, mining and bulk-material handlers, automotive OEMs, and metal recyclers; no public pricing exists, and contracts are negotiated bilaterally through global field sales teams supported by regional manufacturing and distribution.

Ownership remains concentrated in the founding Delachaux family (now in its fourth generation), with La Caisse de dépôt et placement du Québec holding a strategic minority stake acquired in 2018 alongside the family buyout of CVC Capital Partners. The Group has executed an active M&A program under family stewardship: acquiring Frauscher Sensor Technology (2019, sold to Wabtec in December 2025 for €675 million enterprise value), Jay Electronique (2019), and LJU Automatisierungstechnik (2017); divesting KLK Electro Materiales (2022); and opening a new manufacturing site in Wuhan, China (2018). The December 2025 Frauscher exit materially strengthened the balance sheet and refocused the Group on Pandrol, Conductix-Wampfler, DCX Chrome, and Lenoir-Mec.
