Pre-engineered metal buildings require precise coordination from foundation to finish. Sentry’s self-performed approach means our Structural Steel division handles erection, our FieldWorks team coordinates foundations and anchor bolts, our Crane Service manages heavy lifts, and our Electrical and Mechanical divisions complete the building systems.
Need a crane-ready structure? Our Engineering team designs the tie-ins and our crews install them. The result is a complete building delivered by a single team with accountability from day one.
We sell and install Nucor Steel Buildings across South Dakota and the Midwest.
