Our story

From a 450 sq. ft. shop to a group of complementary experts

Founded by Jean-Marie Tremblay in 1953, the company expanded its facilities and services while maintaining its family roots.

Humble beginnings in 1953

Jean-Marie Tremblay founded a company specializing in ornamental iron fabrication in 1953. The company, then known as Group Tremblay Welding, began in a 450-square-foot shop.

As client needs evolved, the company expanded its expertise, facilities and the nature of its work.

Company milestones

  1. 1953

    Founding

    The ornamental iron fabrication shop opens.

  2. 1963

    Relocation

    The company moves to Salaberry-de-Valleyfield into a shop five times larger than the first.

  3. 1974

    Cathode plates

    That year marked the start of cathode-plate production and exports to the United States, South America and Europe. That expertise is now carried by Placatech, which also repairs and recycles aluminum cathodes by friction stir welding.

  6. 1997

    Expansion

    The facilities quadrupled over ten years. That year also brought a Banque Nationale SME bronze medal and ISO 9002:94 accreditation.

  7. 2012

    Ownership evolution

    The company begins a share-ownership process and welcomes a new management team.

From the shop to an integrated model

The company’s evolution was about more than expansion. Engineering and detailing, erection, maintenance, custom scaffolding and building cladding developed around fabrication.

Those areas of expertise now sit within GTI, Soudure JM Tremblay, ISTA, K2, GT-R and Placatech. On structural steel projects, they can contribute to a coordinated scope from engineering through the field.
