New Millennium Building Systems

Design-Build Firms


The time-honored approach of the master builder is fully supported by our collaborative process of steel joist and metal decking design.

We are uniquely prepared to support the design-build process by way of our distinct business advantages: flexibility in the design, manufacture and delivery of special profile steel joists, steel joists and metal decking.


This flexibility at every phase enables us to seamlessly support your team; to collaborate and exchange digital, three-dimensional steel joist plans using our new BIM steel joist design component, to help you control costs and schedules, and to make certain that concept-to-completion is not just a theoretical possibility, but a reality carved in steel.


  • Improve the process by improving the structural steel package
  • Achieve your architectural vision with our special profile joist designs
  • Total project cost accountability
  • Seamlessly move from concept through design collaboration
  • Detect, remove and prevent clashes before they occur
  • Quickly adjust for any steel joist or metal deck design contingency
  • Accommodate any need for staged or JIT deliveries
  • Easily adapt to changes in the project schedule
