3N-32 PLN3-32 Metal Deck Rendering

3.0″ Type N-32

3N-32 is a high-strength, deep profile roof deck used for larger span applications. The 32" cover width makes for less handling time and faster erection vs. N-24 as well as greater shear values. If you need help with a speciation or design intent, give us a call.

    Description

    The 3N-32 metal deck is a deep roof profile at 3" deep. This roof deck is designed to cover larger spans with fewer supports. typically found in expansive roofing projects due to its higher engineering properties vs. the older N-24 profile.

    N-32 Sidelap Attachment(s)

    Metal deck sidelap attachments are the fasteners that connect adjacent sheets of steel deck at their overlapping edges, commonly known as side laps. The EOR or design team, is responsible for specifying the type and spacing of sidelap attachments. This specification is crucial as sidelap attachments play a vital role in the structural integrity of the metal deck, the diaphragm to resist lateral forces from wind or seismic activity.

    Interlocking Screwed Sidelap

    STITCH SCREWS

    High Shear Stitch Screw sidelaps are designed to be fastened by stitch screws. This type of metal roof deck is designed to be screwed at the side lap and NOT welded. Normally stitch screw is used in short to medium span conditions.
    Standard Nesting or Lapping Sidelap

    NESTABLE

    Nestable deck is also designed generally for screw side lap style of B decking. Note the nestable side lap has a lower shear value and must be determined by the EOR.
    Welded Interlocking Sidelap

    WELDED

    Interlocking sidelaps without a proprietary sidelap tool indicate a top seam weld or button punch is required. Note this is can / would be the same deck profile as PLB or DGB however, the attachment pattern would indicate the proprietary tool may not be required.
    PROPRIETARY INTERLOCKING SIDELAP TOOL

    PROPRIETARY CONNECTIONS

    Propriety sidelap connections require the use of the manufactures proprietary sidelap connection tool. These tools must be used for the side lap attachment or the building design could fail. Below are the most common sidelaps connections in the market.

    • PLN3 (PunchLok)
    • DGN-32 (Delta Grip)
    • NW-32 (RED Rolling Electric Deck)

    N-32 Finish Options:

    The metal deck finish is the coating on the steel deck surface, which will vary depending on the application. The EOR or design professional is responsible for specifying the finish of metal deck on a job by job basis.

    • Roof deck finishes are most commonly shop coated, G-60 and G-90 varieties.
    • Composite deck finishes typically uses galvanized steel to promote a bond with the concrete. Note composite decks cannot have a painted top surface as it creates potential bonding issues between the concrete and the metal deck.
    • Form deck finishes are most commonly to be galvanized, or galvanized top with a painted bottom.

    PRIME PAINT

    		 A1008 Prime Painted Steel Decking: A temporary, provisional primer (gray or white) applied to cold rolled steel, offering protection before field-applied finishes and most often used for roof deck.

    G-30

    		 A653 Galvanized G-60 zinc coated steel is the standard in the deck industry. G30 has approximately 0.3 ounces of zinc per square foot. Generally for warehouse or large sq ft.

    G-60

    		 A653 Galvanized G-60 zinc coated steel is the standard in the deck industry. G60 has approximately 0.6 ounces of zinc per square foot.

    G-90

    		 A653 Galvanized G-90 is typically specified for exterior applications or more corrosive enviromentys with approximately .9 ounces of zinc per square foot.

    FINISH PAINT

    		 A653 Finish Paint: Specialty finishes (Epoxy or Tenmic) can be applied either pre- or post-manufacturing, most common in highly corrosive environments rather than architectural coats.

    GALV + PAINT

    		 A653 Galvanized + Paint: A combination of galvanization and primer, ideal for projects requiring both corrosion resistance and the ability to apply additional field paints.

    PHOS PAINT

    		 A1008 Phosphatized Painted: Steel decking with a phosphatized black surface that develops slight rust before concrete is poured, with the underside painted for additional protection.

    Cellular, Acoustical & More

    3" Deep N32 comes in variations such as acoustical, cellular, or vented metal decking are generally specified by the EOR or design professional to meet requirements on a project. The choice of a variation is determined during the design phase and typically requires a special manufacturing process, or coil. Note these variations are often indicated structural design drawings or specifications.

    N-32 Acoustical Metal Deck Rendering

    N32 ACOUSTICAL

    Acoustical steel deck refers to metal deck which has perforated webs and/or flanges, then sound-absorbing insulation is laid into the flutes of the deck to minimize sound reverberation within a room. the NRC, or Noise Reduction Coefficient serves as the measure of sound absorption and is the value required is generally specified by the design team.
    N-32 Cellular Metal Deck Rendering

    N32 CELLULAR

    Cellular metal deck consists of a flat bottom steel sheet with a deck profile attached either by welds or rivets. This creates pockets or cells where the deck that can be used for various purposes such as electrical wiring to be threaded through.

    N-32 Cellular + Acoustical Metal Deck Rendering

    N32 CELLULAR ACOUSTICAL

    Cellular Acoustical applications come with factory-installed sound-absorbing insulation into the flutes or cells of the metal deck. Cellular acoustical decks are available in both roof and floor deck profiles offering the same structural capabilities as the standard deck profile

    Metal Deck Hangar Tab Vents

    VENTED

    Slotted or vented metal roof deck offers factory-punched vent tabs to ensure effective airflow to aid in curing concrete or to prevent moisture from being trapped in the slab during slab waterproofing applications. Consider that when venting metal deck, minor leakage can occur during concrete placement. The row configurations vary by profile; contact us for more details.
    HSB-PLB FULLY PERFORATED RENDERING (PLB/HSB FP 11/21%)

    FULLY PERFORATED

    Fully perforated metal deck has evenly spaced holes across its surface, allowing airflow and/or visibility. This design provides partial steel deck while allowing for ventilation, sound, or reduced wind loads, making it ideal for exterior cladding, equipment enclosures or other visual screening purposes.
    CURVED METAL DECK

    CURVED METAL DECK

    Curved metal deck in the refers metal deck curved along their length, or the direction where they are strongest. We are able to curve metal deck in the strong axis to create architectural features like curved roofs or walls, as this allows the deck to follow the desired shape while maintaining its structural integrity.
