New Millennium engineers and manufactures standard steel joists, architecturally unique "special profile" steel joists, and steel decking. The company is a nationwide leader in BIM-based steel joist design and BIM process management. New Millennium has also introduced the Flex-Joist Tension-Controlled Open Web Steel Joist design approach for increased steel joist strength, reliability and ductility. Among the benefits of the new approach is enhanced building safety, providing an early warning in the event of a roof overload condition.
This specification includes New Millennium steel form deck and steel composite deck that is designed and manufactured nationwide at our six plant locations in accordance with the specifications of the Steel Deck Institute.
