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.
