New Millennium Building Systems



We're the steel joist and metal decking supplier that can help with more than the drawings.

You need a steel joist and metal decking manufacturer that is ready, willing and able to help address the consequences of accelerating schedules and impatient owners. You need a partner who is proactive about the steel detailing and structural engineering. You need a partner that wrote the book on special profile steel joists, and pioneered the use of BIM in steel joist design. You need an accessible resource that can drive the specifying process, that resolves issues rather than assigns blame, and will visit the job site or the office as needed to keep things moving.


At New Millennium, we ask the important questions and stay on top of a job to keep it from slowing down. Read how our team can help shorten the RFI process.
