Nationwide resource for steel joists, metal decking and castellated beams

New Millennium Building Systems produces three types of steel products, all used in the construction of non-residential buildings. One type is fabricated steel joists, trusses, and girders used to support a building's roof and floors. Another type is metal decking, which is applied over the steel joists to serve as a base for the floor or roofing. New Millennium offers castellated beams for a highly architectural and cost-effective structural option across large spans up to 100 feet.
