ASC Steel Deck

It is our objective to provide the highest quality

products and services in the steel deck industry. This objec-

tive is partially accomplished through conducting extensive

testing programs with independent testing facilities to

ensure that our products comply with the stringent criteria

of today’s building codes. Our steel deck products have

been evaluated by the International Conference of Building

Officials (ICC Evaluation Services Report No. 1414), listed

by Underwriters Laboratories, Certified by the Steel Deck

Institute and approved by Factory Mutual and City of Los

Angeles. Additionally, our manufacturing plants are strategi-

cally located in the western United States so that we may

provide the best possible service. Most importantly, our

Sales Representatives, Customer Service and Engineering

Services Departments are prepared to assist you with the

specific requirements of your project.

General Notes


The following notes apply to the allowable total load tables and/or

to the allowable superimposed load & diaphragm shear tables.

1. Arc spot or arc seam (puddle) welds shall have an

effective fusion area, to supporting members,

equivalent to at least 3/8" by 1" long or 1/2" in diameter.

2. Spacing of marginal welds to members parallel to the

flutes:

(a) Arc spot (puddle) welds to members, such as

chords, and to collector elements, such as struts

or ties, shall have a spacing in feet equal to

32,000 (t) /v, where:

t = Uncoated steel thickness of fluted deck in

inches. (see ICC report for "t")

v = Actual diaphragm shear at marginal supports

or actual shear transferred to collector (at

struts or ties) in pounds per foot.

(b) Fillet welds to members, such as diaphragm

chords, shall have a spacing in feet equal to 480

I w / v, where:

lw = Length of weld in inches (not less than 1 1/2”

v = Actual diaphragm shear to be transferred to

chords in pounds per foot.

(c) Fillet welds attaching the diaphragm to struts, ties

or other collector elements shall have a spacing,

in feet, equal to 300 I w / v where:

v = Actual diaphragm shear to be transferred to the

collector element, in pounds per foot.(d) In no case shall any weld spacing exceed 3'0".

3. Attachments at interior lines of shear transfer,

perpendicular to deck corrugations:

(a) The shear transfer from a diaphragm to interior

ties or strut lines, perpendicular to deck

corrugations, shall not exceed the shear values

indicated in the tables. Two lines of puddle welds

may be used to develop the actual shear transfer to

these collector elements.

4. The minimum 28-day compressive strength for

structural concrete shall be 3000 psi and the density as

indicated in the tables or as required for fire rating. The

minimum depth of concrete shall be 2" over the top

flange and it is to be reinforced with a minimum 6 x 6

W1.4 x W1.4 welded wire fabric. The reinforcement shall be

placed near the center of the fill, over the top flange.

If fill exceeds 3 1/4" thick the reinforcement area must

equal 0.00075 times the depth of fill over top of deck, each

way.

5. All decks with structural concrete fill may be considered

rigid diaphragms, f<1.0, unless otherwise noted.

6. Shoring calculations are based on the deck profile

supporting the dead load of concrete, plus either:

(a) a 20 psf uniform construction load, or

(b) a 150 lb. concentrated live load for flexure.

The dead load deflection is limited to L/180, but not to

exceed 3/4".

7. Total SlabThickness: is the nominal total slab depth,

measured from the bottom flange of the rib to the top of

the concrete.This applies to all allowable

superimposed load and diaphragm shear tables.

8. For all cellular profiles, the first number of the gauge

designation (20 /20) refers to beam section (corrugated

profile).The second number (20/ 20) refers to the pan

section (flat plate).

9. Seam attachment for composite floor deck to beminimum button punch @ 36" O.C.

10. Typical floor deck manufacturing tolerances:

Panel length: +/- 1/2"

Thickness: Not less than 95% of the design

base metal thickness

Panel cover width: -3/8", + 3/4"

Panel camber/sweep: 1/4" in 10' length

Panel end out of square: 1/8" per foot of panel width

The above SelectionTable is based on following criteria:

1. Normal weight concrete (150 pcf).

2. Horizontal and vertical deflection is limited to 1/4” maximum for concrete dead load

3. Design stress is limited to 20 ksi for concrete dead load temporarily increased by one-third for the construction live load of 20 psf.

4. Pour Stop Selection Table does not consider the effect of the performance, deflection, or rotation of the pour stop support which may

include both the supporting composite deck and/or the frame.

5.Vertical leg return lip is recommended for type 16 and lighter.

6.This selection is not meant to replace the judgement of experienced Structural Engineers and shall be considered as a reference only.

Materials and Finishes

The B, N, 2W, 2WF, ASC2, ASC3, 3W and 3WFprofiles are manufactured from steel conforming to ASTMA653 (Fy=38ksi). CF profiles are manufactured from steelconforming to ASTM A653 (Grade E), except CF 1 3/8 (18 ga)which is manufactured from steel conforming to ASTM A653

(Fy=38ksi).The standard galvanized coatings are G-60 (.60 oz./ft2)

or G-90 (.90 oz./ft.2) in accordance with ASTM A653. TheB, 2W, 2WF, 3W, 3WF ASC2 & ASC3 are available inG-60 and G-90. The CF profiles are available in G-90.Please inquire for the availability of alternate coatings.

Please Note: spot weld discoloration will not be a reasonfor rejection of cellular deck.

The cellular decking listed in this catalog is manufac-tured from two sections of galvanized steel that are joined

with resistance welds.The deck coating and finish willbe removed, from the area of the resistance weld, duringthis process. This condition should be considered whendetermining the fitness of this product for a specificapplication. This condition will also not be an acceptablecause for rejection of the material. Please contact yourASC Steel Deck representative for additionalinformation on this subject.
