Product information design
  1. Cordeck certifies that our Roof Deck has been evaluated in accordance with the applicable SDI Standards and property values for the Uniform Load Tables and meets or exceeds SDI requirements.
  2. Load shown in tables is uniformly distributed total (dead plus live) load in psf (kPa). Loads in shaded areas are governed by live load deflection not in excess of L/240, the dead load included in 10 psf (0.478.kPa). All loads are governed by the allowable flexural stress limit of 20 ksi (140 Mpa) maximum yield steel. Where heavy construction loads or other unusual concentrated loads are anticipated during the lifetime of the deck, the specified live load must be increased to offset the effects of the abnormal concentrated load. See Maximum Spans for Construction and Maintenance Loads in the SDI Design Manual.
  3. The rib width limitations shown are taken at the theoretical intersection points of the flange and web projections. Depending on the radius used, the load table could vary from that shown.

All steel to be used in Cordeck Roof Deck will be galvanized, prime painted, or a combination of the two.

  1. Prime Painted
    • Roof deck shall receive one coat of standard gray primer paint over cleaned and pretreated steel.
    • The primer coat is intended to protect the steel for only a reasonably short period of exposure, in normal atmospheric conditions, and shall be considered an impermanent and provisional coating.
    • Field painting of prime painted material is recommended especially where the deck is exposed.
  2. Galvanized
    • All steel shall be coated to conform to ASTM A924 G-60 or G-90 or to Federal Specification QQ-S-775.
    • Galvanized finish in G-90 coating is desirable in high moisture atmospheric conditions.
    • Cordeck shall not be responsible for the cleaning of the underside of steel deck to ensure bond of fireproofing. Adherence of fireproofing material is dependent on many variables. The adhesion ability of fireproofing materials is the responsibility of the fireproofing applicator.
  3. Accessories
    • Cordeck can supply ridge and valley plates, cant strips, finish strips, sump pans, end and side closures, pour stops, deck plate, rubber cell closures, screws, and other accessories needed to complete the project.
  1. All steel deck material is manufactured by SDI members or manufactured in accordance to SDI.
  2. Cordeck certifies that all material will be in accordance with the SDI Cellular Deck Manual specifications.
  3. Cordeck Roof Deck conforms to all applicable SDI Roof Deck Manual specifications.
  1. Cordeck Steel Roof Deck shall be installed by qualified and experienced workers.
  2. Roof deck installation drawings shall be submitted to the project architect and engineer for approval prior to the manufacture of materials.
  3. Steel roof deck shall be placed in accordance with approved erection drawings.
  4. End laps shall be a nominal 2” and positioned over supports.
  5. Position each deck unit on a supporting structural frame. Adjust to final position with accurately aligned side laps and ends bearing on supporting members. On joist framing, be sure the appropriate end laps occur over a top chord angle for proper anchorage.
  6. When one row is placed end to end, begin another, making alignment adjustment if necessary.
  7. Each deck unit shall be placed on supporting steel framework and adjusted steel framework and adjust.
  8. Cutting of openings through the deck and all skew cutting shall be performed in the field. Openings not shown on the erection drawings such as those required for stack, conduits, plumbing, vents, etc., shall be cut, and reinforced if necessary, by the trades requiring the openings.
  1. Roof deck sheets shall be attached as soon as possible after placement. All sheets placed shall be attached prior to the end of each work day. Arc welding is the most commonly used method for attaching Cordeck Steel Roof Deck to structural supports. Welder shall immediately follow the placement crew.
  2. All welds are to be made from the top of the deck down through the bottom flange of the ribs. Welds shall penetrate and attach all thickness of material to the structural supports.
  3. Caution shall be exercised on the selection of the electrodes to provide positive attachment and to prevent high amperage blow holes.
  4. Puddle welds shall be at least 5/8” diameter or elongated puddle welds with an equal perimeter. Fillet welds, when used, shall be at least 1” long.
    • Roof deck ends shall be welded to structural supports at 12” on center maximum and 18” on center maximum at intermediate supports.
    • Various mechanical fastening systems other than welding are recognized as viable anchoring methods provided that they are reviewed, approved, or specified by the project designer. These include but are not limited to power-activated or pneumatically driven fasteners and screws.
    • When spans exceed 5’-0”, side laps shall be fastened together at a maximum spacing of 36” on center.

Attachment must be determined by the designer as part of the overall building design process. Values given in this document are adequate in most cases.

Storage and Handling
  1. Protect steel deck from corrosion, deformation, and other damage during storage, handling, and installation.
  2. Deck not promptly erected shall be stored off the ground, with one end elevated to provide drainage. Bundles must be protected against condensation with a ventilated waterproof covering.
  3. Bundles must be stacked so there is no danger of shifting or material damage. Bundles must be checked for tightness, and retightened as necessary.
  4. Deck bundles on the building frame must always be placed near a main supporting beam, at a column, or a wall. In no situation are the bundles to be placed on unbolted frames or unattached and unbridged joists. The structural frame must be properly braced to receive the bundles.

There are many ways to wire a building, but only one cabling distribution system effectively addresses a certainty of every building ever constructed – change.


Key Benefits & Features


Maintains unobstructed sight lines in open floor plan designs. Eliminates the need for ceiling to floor power poles. Works with any floor covering – carpet, wood, tile, etc.


Locate it. Wire it. Activate it. No ladders. No core drilling.


Structural steel decking is a given requirement. In Floor systems utilize this given. Eliminates expensive raised access floors, cable trays, core drilling and poke-through devices, and plenum-rated cable.


Reconfigure a space any time to serve new purposes, office churn, new tenants, etc.


Highly flammable and toxic cabling is safely encased in concrete instead of within ceiling plenums. Burning cables produce highly lethal fumes including cyanide, chloride, carbon monoxide and dioxin.


Cabling located inside steel raceways provides enhanced RF shielding (electromagnetic interference).


No core drilling means no noise, dust, water, heavy equipment – ever. Improves marketability of leased office space as electrical build-outs are far less expensive and easier than alternatives.


Cables perfectly organized – from closet, to trench header, to raceways, to outlets.


Data and telecom cables are tamper-resistant and encased within the structural steel framework. No cabling runs from the floor below.


No hollow feel and echoing sound of raised access floor. Eliminates need for poke-through core drilling through the floor slab which weakens the structural integrity of a floor.


Carcinogens found in cables include lead, cadmium, and others. As cables age these toxins can slough off cables, contributing to unhealthy air quality. With In Floor systems, cables are encased in steel and concrete, greatly reducing this concern.

Competitive Comparison

Cordeck’s In Floor Cellular Raceway Systems provide the important benefit of a low life cycle cost.

Expenses required to install the system or modify the workplace environment are minimized. Cables are installed within the cells of the metal deck, eliminating the added costs of plenum rated cables required by some systems. Economically, Cordeck is the best choice for your wire management needs.

Read on to see how the long-term savings realized when using the Cordeck System mitigate the minor difference in cost per square foot.

Poke-Thru vs. Cordeck In Floor Cellular Raceway Systems

Option 1: Poke-thrus in composite floor deck, power and data fed with EMT conduit

Option 2: Poke-thrus in composite floor deck, power fed EMT conduit, data in cable trays

Poke-Thru Disadvantages

  • Core-drilling and related coordination required after final space planning
  • Poke-thrus create ceiling clutter
  • Exposed cables create potential for security breach from adjacent floors
  • Moves and changes cause business disruptions and are costly

Cordeck In Floor Advantages

  • Presets easily accessed after space planning is complete
  • Completely contained within concrete floor slab
  • Moves and changes cost is less than half of the unit cost for poke-thrus
  • System accessible at finished floor
  • Moves and changes can be performed during business hours with no interruption to adjacent tenants
  • The Cordeck In Floor System includes over 1,500 activation points for future flexibility at no additional cost
Raised Access Floor vs. Cordeck In Floor Cellular Raceway Systems

Option 3: Has a 6-inch raised access floor on composite deck slab with power fed MC Cable and data in Cable Trays

Option 4: Has 6-inch raised access floor on composite deck slab with Plug-n-Play Power Management, and data in Cable Trays.

RAF Disadvantages

  • Much greater overall project cost
  • Increased floor to ceiling heights
    • Added curtain wall
    • Added steel structure
    • Added elevator travel
    • Added stair height
  • Additional trade needed to install system
  • Accessible data cabling poses security threat
  • RAF provides environment that may negatively impact building and employee health
Poke-Thru Additional Activation Costs

Average cost of initial installation: $3,258
Average cost after occupancy: $6,700

Cordeck Additional Activation Costs

Average cost of initial installation: $3,017
Average cost after occupancy: $1,200

Unlike a poke-thru system where multiple trades are involved in adds and changes, cost savings are realized with the Cordeck Solution because most or all of the work is simply completed by the facility's maintenance team.
