Who are we ?

With a century of experience, Tréfiunion is recognized and appreciated by its many customers.

Let's get acquainted...

Close to the Paris – Nancy axis, the town of Commercy, in the Meuse, hosts the head office of Tréfilunion, which has a second manufacturing site in Sainte Colombe sur Seine, in the Côte d’Or.

Our core business is based on the drawing of steel wires for diameters ranging from 0.95 mm to 13 mm for steel wires (cut into 2 families: mild steels and hard steels) and for stranded wires between 5.2 and 15.7mm.

Our knowledge of the market is ensured by a dynamic and motivated sales team, attentive to its customers while carrying out the daily search for new prospects and new outlets.

Our know-how and seriousness have enabled us to obtain ISO 9001 certification. To respond to the growing concerns of our partners and customers, our objective is to obtain QSSE certification (9001 + 14001 + 45001) in the short term.

With the customer at the heart of our concerns, we strive to combine success and reliability.

A small but united and determined management team.

Entrepreneurial mindset

After the sale by ArcelorMittal in 2019, tréfilunion was able to bounce back by demonstrating its agility by becoming a full-fledged SME.

Spirit of innovation

Producing quality steel wires, respecting the expectations of our customers and while seeking the best techniques to limit environmental impacts, such is the challenge that we take up on a daily basis.

Excellence and Integrity

Adapting to better serve our customers and thus guarantee the best possible quality is now a must on our two sites.

Two sites, two productions.

The Meusian site of Commercy specializes in the production and delivery of hard steel wires and mild steel wires, so named according to their mechanical characteristics and therefore their future applications for our customers.

In Sainte Colombe sur Seine, production is dedicated to strands and single wires intended for construction applications, in particular for all prestressed concrete.
