Plan Your 2026 Steel Building Project Call 406 240-2508
Most companies will sell you a steel building kit. Cornerstone Steel builds your steel building, from site selection and engineering through permitting, construction, and move-in. We are a Montana contractor working with Montana clients, under Montana codes, in Montana weather. There is a difference between buying a kit and having a partner on the ground.

We are not a national kit supplier routing your order through a call center. We are a Missoula-based company that has built relationships with engineering firms, city and state regulatory agencies, sub-contractors, and suppliers throughout western Montana. Our reputation is local and it is verifiable. Ask the clients in our gallery. Ask the engineers who spec our projects. Ask the inspectors who sign off on them. Our best sales pitch is not on this page. It is in the voices of the people we have built for.
Montana is hard on buildings. Heavy snow loads, high winds, seismic requirements, and temperature swings that push materials to their limits. Every Cornerstone steel building is engineered to meet Montana’s specific structural codes and climate demands. We work with Chief Buildings and CBC Steel Building systems, two of the most respected names in pre-engineered steel, and we integrate them with traditional building materials when your project calls for it. What you get is a building that performs here, not just anywhere.
Steel Buildings for Every Montana Application.
Cornerstone manages every phase of your project so you do not have to coordinate between architects, engineers, contractors, and inspectors on your own.
