Built on Execution, Sustained by Trust
United Steel began in 1974 as East Hartford Welding, founded by Kenneth F. Corneau with a commitment to quality fabrication and reliable service. Five decades later, we’re New England’s largest structural steel fabricator and erector—still family-owned, still operating from East Hartford, and still guided by the same values that built the company.
From a regional fabrication shop to a full-service structural steel contractor with 200+ employees and a 200,000-square-foot facility, our growth has been built one successful project at a time.
Our Mission
United Steel exists to give construction managers and contractors the structural steel partner they can trust at every phase. Our mission centers on four principles:
- Execution—We deliver what we say we’ll deliver, on the schedule we commit to.
- Precision—Every component is fabricated to specification. Every drawing is coordinated before production starts.
- Accountability—One team manages your scope from award through closeout. No gaps, no handoffs, no surprises.
- Long-Term Partnerships—Our 98% client retention isn’t a marketing number. It’s the result of consistently doing the work right.
