Structural Steel Building Systems
New Millennium is a nationwide supplier of custom engineered and manufactured structural steel building systems. We are called upon early in the design-build process to explore our extensive portfolio of building system options. For multi-story projects, we offer the broadest range of long-span composite floor systems. We are the leading provider of special profile steel joists for unique rooflines, and architectural steel deck for exposed ceiling and cladding applications. We also engineer and produce standard steel joists and decking for projects of all sizes. New Millennium pioneered the use of BIM-based steel building systems design to assist early project design collaboration.
Increased steel joist performance metrics - when and where you need them Laboratory testing has consistently demonstrated the Flex-Joist™ design to exceed standard steel joist design for strength, reliability and ductility.
Standard Deep-Dek® is a single cell (hat) unit that provides a support surface for various types of roofing materials. It can be used as a secondary structural member to provide for lateral force distribution to the structure's vertical force resisting systems. Deep-Dek® products produce a deep fluted look for dramatic underside aesthetics.
Cellular Deep-Dek® is a single cell (hat) unit with the liner panel that provides a support surface for various component roof systems. It can be used as a secondary structural member to provide for lateral force distribution to the structure's vertical force resisting systems. Cellular Deep-Dek™ products produce a smooth underside surface with subtle shadow lines for a clean finished look.
Type 1.0RD roof deck provides an economical option when support spacing is small. Where rigid roofing insulation is used with 1.0RD deck, a minimum 1" thickness is required.
Type B (Wide Rib) roof deck provides the best balance of strength and economy of all the 1" deep roof decks. Where rigid roofing insulation is used with B deck, a minimum 1" thickness is required.
BC-Dek is a 1" deep cellular structural roof deck unit that provides a support surface for various types of roofing materials. The liner panel with Dek-Knek™ Sidelap Attachment System provides a finished underside ceiling with self-aligning sidelaps and concealed fasteners. The acoustic version BCA-Dek features a perforated liner panel, providing a noise reduction coefficient (NRC) value of 0.70 when used with a rigid insulation. Fiberglass insulation batts are installed in the BCA-Dek cells at the factory under controlled conditions.
Inverted N Deck is the 3" N-Dek profile placed in the inverted position for a unique ceiling aesthetic appearance. The finished look provides a smooth ceiling appearance with heavy shadow lines. INA-Dek is a 3" deep, wide rib, inverted, acoustical structural roof deck unit that provides a support surface for various types of roofing materials with an NRC rating of 0.80 when used with rigid roofing insulation.
Types NW32 and N are 3-inch roof deck profiles that make large open spaces possible in structures such as gymnasiums, limiting the number of structural supporting members required. Choose from 32-inch coverage, standard 24-inch coverage, cellular and inverted configurations. NW32 is available with nested or interlocking side laps. N deck is available with nested side laps only. All NW32 and N deck variations are available with acoustical options.
- Available with nested side laps or interlocking side laps
- Available as an acoustic deck manufactured with perforations in the vertical ribs, type NW32A and NW32IA having an NRC rating of 0.70 to 0.95 when used with rigid roofing insulation
- All NW32 deck is FM-approved for use as a component in Classes 1-60, 1-75 and 1-90 wind uplift construction
- All NW32 deck types are UL-, FM- and ICC-approved
Form deck is available in lengths from 6'-0" to 40'-0". Please check with your local New Millennium facility for lengths outside these parameters. Conforms to ASTM A1008/A1008M for uncoated and painted deck, A653/A653M for galvanized deck. Approved by UL, LLC and listed in the UL and ULC Fire Resistance Directories.
For clear spans up to 36 ft., Versa-Floor™ systems featuring Deep-Dek® Composite are the longest spanning floor systems available.
Deep-Dek® Composite combines the structural advantages of a flat-plate slab with the time and cost-saving advantages of a permanent form slab. Span-to-depth ratios equal those of traditional cast-in-place concrete and hollow-core plank. Space-saving Deep-Dek Composite floors weigh less than equivalent concrete floors and install faster.
Exposed ceilings two distinct aesthetics Choose from a deep-fluted appearance or a smooth surface with thin structural ribbing. Available in a variety of finish options. The smooth surface of Deep-Dek Composite Cellular Acoustical also allows for optional acoustical treatments.
Optimize multi-story construction to reduce cost and increase safety, you can pre-assemble panels up to 30-ft. wide on the ground using our Panelized Delivery Method'. Unshored concrete pours for spans up to 22-ft. and shored for spans up to 36-ft.
Reduce costs by eliminating suspended ceilings. When left exposed, the dovetail design provides a clean, lineal-plank aesthetic for office, retail, and academic spaces. Versa-Floor' is non-combustible and is fire-resistance rated up to four hours without protective coverings such as gypsum and spray-on materials.
Optional acoustical treatments up to NRC 0.85 control noise reverberation within occupied spaces. Versa-Floor' can be supplied with a factory-applied primer option. Versa-Wedge' is a hanger system to suspend lighting or facilitate MEP integration.
Versa-Dek® Composite systems are ideally suited to work with light gauge structural steel wall systems. It also integrates with any beam or other bearing-wall method. Monolithically cast concrete finishes flat so it eliminates grouting and floor leveling activities.
Even when assailed by the progressive strategies of design-build and integrated project delivery (IPD), an invisible wall keeps the non-residential construction industry from reaching its greater potential. To move beyond the fifth wall, we must first recognize that it exists - and that we now have the means to break through.
