BCM designs and manufactures finished and semifinished metal products.
We are recognised experts in the field of metal processing by forming and machining, in addition to assembly work.
BCM has adopted a whole new management concept that encapsulates our constant quest for customer satisfaction, our trust in our people, and our innovative spirit.

A family background

Martine Buathier and René Mollard created BCM Métallerie in 1991 to meet the needs of a major name in outdoor advertising.
Sébastien Buathier took control of the company in 2005 and introduced another dimension by adding a design office, developing a strategy of greater diversification and introducing a customer-focused organisation.
