Who are we?

As a sound and historical stakeholder in surface treatment, the LOUIS Group has managed to preserve a family-based and independent group spirit since its creation in 1923. Established in the West of France via its 5 companies specialised in hot-dip galvanising, the LOUIS Group accompanies its customers every step of the way thanks to the experience and responsiveness shown by its 220 employees.

A group at its customers’ service

Acting as partners for our customers, and in complying and remaining flexible as regards our production lead times, the LOUIS Group makes every effort to continuously improve its production tools. We listen to our customers’ needs and support them throughout their design process, to ensure service and galvanisation in line with market requirements and standards in force.

The work of men, the strength of a group

As the fruit of close collaboration between our sales and technical divisions, the LOUIS Group commits to its highly-demanding customers, to remain in phase with market trends. Able to undertake large-scale projects in France or abroad, the LOUIS Group protects all types of private or public works from corrosion.


Since its creation in 1923, the LOUIS Group has founded its work on a genuine entrepreneurial culture, and on considerable autonomy for all 5 of its subsidiaries. René and Patricia LOUIS are brother and sister; they are the 3rd generation to manage the Group and have been at its head since 1984.
