Select from a wide range of steel roof decks, form decks, and composite decks

All steel decking is available in lengths ranging from 6’-0” to 40’-0”. Extra charges are applied to lengths less than 6’-0”. Contact New Millennium if lengths exceeding 40’-0” are required.

 

Roof, form, and composite decking is manufactured from steel with a yield strength of up to 80ksi, conforming to ASTM A1008/A1008M for uncoated and painted deck and A653/A653M for galvanized deck. Refer to published tables for the minimum yield strength used for each deck type; contact New Millennium for availability of higher yield strengths when required.

 

 

Primer-painted or galvanized finishes are available for New Millennium steel decks. The standard primer-painted finish is gray on both the top and bottom sides. The galvanized finish is available in G30, G40, G60 and G90 coatings. Decks can also be furnished with a two-coat bright white primer bottom side combined with either a primer-painted or galvanized topside. The primer-painted finish is intended to protect the steel for a reasonable installation period while exposed to ordinary atmospheric conditions and shall be considered an impermanent and provisional coating. Always store steel deck off the ground with one end elevated and protected from the elements with a weatherproof covering that is ventilated to avoid condensation.

 

Roof deck, form deck, and composite deck attachment to supports can be made either by welding using a minimum visible 5/8" diameter puddle weld or properly designed mechanical fasteners, spaced an average of 12” on center, not to exceed 18” on center. Weld washers must be used on all deck units that are less than 22 gage. Side laps are to be fastened together between supports at a maximum spacing of 36" on center whenever the deck span exceeds 5'-0".

 

All New Millennium decks are approved by UL, LLC and listed in the UL and ULC Fire Resistance Directories.

ROOF DECK

 

New Millennium roof deck types B and N are Factory Mutual approved for use as a component in Class 1-60, 1-75 and 1-90 wind uplift construction.

 

All acoustical roof decks have been tested in accordance with ANSI/ASTM C423 and E795 to determine the noise reduction coefficient (NRC) rating.

 

1.0RD, 1.0RDV Deck

 

  • Type 1.0RD 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.
  • Available with nested side laps only.
  • Available as a vented deck, type 1.0RDV is manufactured with slot vents in the bottom flutes. The openings equal 0.5% of total surface. Type 1.0RDV is to be specified when venting is required for cementitious insulation fill.
  • 1.0RD deck can also be used as wall siding.

F Deck

 

  • Type F (Intermediate Rib) provides an economical choice for applications where insulation requirements are lower.
    Where rigid roofing insulation is used with F deck, a minimum 1” thickness is required.
  • Available with nested side laps only.

B, BI, BV, BIV, BA, BIA Deck

 

  • Type B (Wide Rib) provides the best balance of strength and economy of all the 1 1/2” deep roof decks. Where rigid roofing insulation is used with B deck, a minimum 1” thickness is required.
  • Available with nested side laps, types B, BV and BA or with interlocking side laps, types BI, BIV and BIA.
  • Available as an acoustic deck, types BA and BIA are manufactured with perforations in the vertical ribs, having an NRC rating of 0.60 with a minimum of 1 1/2" thick rigid roofing insulation.
  • Available as a vented deck, types BV and BIV are manufactured with slot vents in the bottom flutes. The openings can be specified from 0.5% up to 1.5% of total surface. Types BV and BIV are to be specified when venting is required for cementitious insulation fill.
  • Also available with rolled-in hanger tabs (non-vented types only).

N, NA Deck

 

  • Type N (Deep Wide Rib) is well suited for applications where it is desirable to space the supporting members as far apart as possible. This is often the case in structures such as gymnasiums where it is usually more economical to minimize the number of long span structural members by using N deck to span large spaces.
  • Available with nested side laps only.
  • Available as an acoustic deck, type NA is manufactured with perforations in the vertical ribs, having an NRC rating of 0.65 with or without rigid roofing insulation.

FORM DECKS

 

0.6FD, 0.6FDV Deck

 

  • Type 0.6FD is used extensively in floor construction as an economical form to support concrete slabs during construction. Specifying 0.6FD deck may eliminate the need for expensive temporary shoring. Floor systems using 0.6FD deck are some of the most economical floors available.
  • Available with nested side laps only.
  • Available as a vented deck, type 0.6FDV is manufactured with slot vents in the bottom flutes. The openings equal 0.5% of total surface.
