Our divisions

Distinct expertise, brought together around the project

Engineering and detailing, fabrication, installation, maintenance, scaffolding, cladding and cathode plates: every division has a defined role.

Metalworking activity connected to the group’s history

A structure designed to coordinate disciplines

Groupe Tremblay brings together specialized divisions that can work independently or contribute to an integrated mandate. Their role is to provide the appropriate expertise at each stage while supporting communication among detailing, shop and field teams.

For a buyer, the first question remains the service required.

How the divisions work together

A turnkey mandate can involve GTI for engineering and drawings, Soudure JM Tremblay for fabrication and ISTA for erection. K2 or GT-R may be added when scaffolding or cladding forms part of the scope.

This combination is not automatic: it is established from the project’s actual needs. The initial inquiry should identify available documents, location, interfaces and schedule so the relevant divisions can be engaged.
