Frequently Asked Questions
Steel frame modular building systems are prefabricated components built with precision FRAMECAD light‑gauge steel. They allow contractors to assemble walls, framing kits, and full structural systems quickly and accurately on site.
FRAMECAD technology produces cold‑formed steel components with exact measurements, reducing layout errors, cutting time on site, and supporting fast, consistent assembly for multi‑story and commercial projects.
Prefab steel building systems are ideal for mechanical rooms, commercial buildings, multi‑family housing, industrial facilities, and institutional projects that require strength, efficiency, and reliable long‑term performance.
Yes. Steel framed modular components resist rot, insects, moisture, and warping, providing a long‑lasting, low‑maintenance alternative to wood framing while maintaining structural integrity over decades.
Project Timeline

Metal Framing Mechanical Room
Harvey's mechanical and plumbing contractor hired B&T to develop the metal framing using our Framecad machines for a mechanical room delivered and set into a large home located in Bozeman, Montana. Harvey's chose this avenue because of the travel and time saving on site.

The Village On Monroe
The Village on Monroe is a new and unique style of affordable housing. A collaborative effort of public and private entities for the reinvestment into the Rapid City community that will make the dream of home ownership a reality for Rapid City's low- to mid-income residents. B&T completed the steel framing for Neighbor Works on the Village on Monroe project for building 607 and 615.
