Our values


Clients are our lifeblood and drive us forward. We are committed to understanding their implicit or expressed needs and providing solutions, challenging their assumptionswhenever necessary. We are focused on meeting their requirements in the execution of the orders they have given us.


To deliver our customers, the joint action of several dozen SCM employees is sometimes necessary. It is together , with this permanent concern for the quality of the products and the delivery times , that we manage to satisfy them. It is as a team that we find solutions to the various problems that may arise in the execution of orders.

It is also as a team that we make progress in our company, without avoiding the confrontation of ideas. At SCM, the individual always takes a back seat to the collective when it comes to arbitrating and making decisions for the good of our clients and our company.

Finally, our company is made up of talented people, simple and humble, committed and tenacious. . Together and as a team, we shine.


While we value robust processes to ensure operational performance, we have a passion for continuous improvement, whether disruptive or incremental. We like to look for new ideas, big or small, in all areas to meet new challenges.

Our teams develop their ingenuity and creativity to go beyond the ordinary.
