58 years of experience at your service

A. & D. Prévost Inc. was founded in 1959, in Richelieu, through the efforts of the brothers Aubert and De St. Denys Prévost. The company’s initial business was limited to aluminum anodizing but quickly diversified to include the design, manufacture, and creation of aluminum architectural products.

Over time, the team was expanded and our facilities were upgraded to make the company the country’s leader in the field. Today, our nearly 130,000-square-foot facilities are at the leading edge of technology, and the approximately 200 employees have acquired an outstanding level of expertise.
