Cahill Fabrication, a division of The Cahill Group, specializes in piping, structural steel, HVAC, and assembly services.

Established in 2006, the Cahill Fabrication Mechanical facility in St. John’s has 3,350m2 to accommodate NDE, hydrostatic testing, post-weld heat treatment activities and passivation. Three separate areas allow for the simultaneous fabrication of exotic and carbon metals. With direct access to major highways and minutes from the St. John’s Port Authority, we are strategically positioned for the efficient transportation of oversized loads.
