Founded by two companions (Mr. Leroux and Mr. Lotz) at the end of World War II to participate in the great enterprise of reconstruction, the small piping/boilermaking company experienced tremendous growth. Benefiting from the industrial development Nantes and Loire estuary, Leroux & Lotz is fast emerging as a major subcontractor to shipbuilding industry.

Through an ambitious industrial policy Leroux & Lotz would, over few decades, become highly diversified: shipbuilding, pressure vessels, petrochemical columns, special machines… The Group Leroux & Lotz is born! It would count in the 80’s, at its peak, nearly 40 companies and over 2,000 employees.

In the 90’s, the decline of the shipbuilding sector destabilizes some companies of the group and they are sold. In 2005, Nantes the group flagship site, is acquired by the young ALTAWEST Group. Solid fundamentals and confidence of historical clients allow the rebound.

Leroux & Lotz Technologies has capitalized on this growth momentum, backed by an investment policy, innovation and international development to position itself as a leading player in energy and environment markets.
