Extending the network (1962-1970)

The STUP international network, formed after the Second World War, was extended during the 1960s. The company developed its business as a construction subcontractor. An increase in orders led to a national structure, with the opening of offices in Marseille, Lille, Nantes, Strasbourg, Lyon, Toulouse and Rambouillet. The company gradually began carving a global foothold and became a preferred partner for all prestressing operations.

Its expertise and countless innovations preceded the company and enabled it to expand on all five continents, in countries such as Canada, Australia, Mexico, Iran and Switzerland. Thanks to these high levels of growth, STUP had operations in nearly 70 countries by the mid-1970s.
