Peikko is currently supplying stud rail for the EAU condo project just north of Montreal. Through the use of stud rail, the Cholette Group (developer of the project) was able to reduce the concrete slab thickness and offer exposed concrete ceilings to their customers. The resulting slim floor also enabled easy coordination of mechanical systems throughout the building.
