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.

Steel joist products include K, LH and DLH Series joists and joist girders, designed and manufactured in accordance with the specifications of the Steel Joist Institute. New Millennium can also provide CJ Series joists (Composite Joist), designed and manufactured in accordance with the specifications of the Steel Joist Institute. We manufacture a complete range of joist products, including bowstring, arched, scissor, double-pitched, and single-pitched joists. Depending on the jobsite location, joists can be furnished as a single-piece up to 15 feet deep and 125 feet long. By using field splices to increase lengths and/or depths, the possibilities are virtually limitless.
