Leaders in architectural aluminum

We manufacture a wide selection of high-quality aluminum building materials for upscale institutional, commercial, and residential markets. We are known for our leading-edge designs and possess unique anodic oxidation treatment expertise.

 Working in partnership with architects, glaziers, and general contractors since 1959, developing curtain wall systems, doors, windows, skylights, and other durable products in innovative designs.

We were the first Quebec manufacturer of High-Performance curtain walls. We manufacture the most efficient and robust windows, equipped with patented MAXSEAL glazing stop. We introduced the P-55 Evolution, first silicone-free curtain wall.

With more than 60 years of experience

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 300 employees have acquired an outstanding level of expertise.
