Buying a steel building in Longmont, CO
Longmont projects are engineered to 2021 IBC adopted by county as adopted locally, using Colorado design criteria: 30–100+ psf by elevation ground snow, 115–140 mph (Front Range gusts) design wind, seismic category B–C. Those numbers change the frame, so we run them for your address before quoting rather than after.
In and around Longmont, self-storage and mini-storage campuses are a steady piece of the work here, so we plan partition layouts, corridor widths and multi-building phasing up front. We quote all three paths — building supplied and installed, or kit only — against whichever fits your Boulder County site.
We also serve Broomfield, Commerce City, Parker and the rest of Colorado, and can sequence freight against your concrete cure so your crew is never standing around waiting on steel.
