A. Composite Metal Deck
1. Sheet metal for deck: ASTM A653, Grade A.
2. Coating on deck and accessories: ASTM A924, G60.
3. Provide deck having integral locking lugs or embossments which provide mechanical lock between deck
and concrete slab. Minimum lug depth: 0.005 inches.
4. Deck units:
a. Capable of supporting weight of wet concrete, plus 20 psf uniform live load or 150 pound
concentrated load per foot of deck width without intermediate shoring on all span conditions, and
without exceeding SDI Specifications limits on deck stress and deflection.
b. Classified by U.L. Building Materials Directory.
c. Each unit or bundle labeled and marked in accordance with U.L. requirements, indicating
manufacturer, testing, and inspection.
5. Deck ribs: spaced no more than 12 inches on center, and designed to provide efficiency factor of 1.0 for
development of headed shear studs in concrete in accordance with AISC Specifications.
6. Provide deck in 36” widths.
2.06. ACCESSORIES
A. Sheet metal closures and fillers: ASTM A446.
PART 3 - EXECUTION
3.01. PREPARATION
A. Do not undertake laying of deck units until supporting members are in place.
B. Clean rust, oil, grease, paint, and debris away from areas to which anchors are to be welded. Remove mill
scale by grinding or by sandblasting.
3.02. DECK INSTALLATION
A. Lay and align units as follows:
1. Maintain required number of units shown on shop drawings.
2. Prevent stretching or contracting of sidelaps.
3. Abut ends of units. Do not lap ends of units.
4. Align flutes in deck at butt joints.
5. Do not use deck units that are bent or kinked or otherwise damaged such as to prevent proper interlocking
and connection of edges to adjacent units.
B. Openings in deck:
1. Deck erector: cut framed openings indicated on Drawings.
2. Holes 12 inches in diameter or less may be cut by trades requiring holes.
3. Where openings greater than 12 inches in diameter not shown on Drawings are required, notify Architect.
Do not proceed to cut deck until Architect accepts proposed openings.
C. Weld deck to supporting steel using 5/8" diameter puddle welds or headed shear studs at not more than 12
inches on center.
D. Coordinate welding sequence and procedure with placing of units.
E. Fasten side laps and connect perimeter edges to supports at spacing not to exceed three feet.
1. Fasten side laps using welds, screws or button punching as indicated on approved shop drawings.
F. Weld metal fillers and closure pieces in place.
G. Replace defective deck connections before concrete slab is placed.
3.03. SHEAR STUD INSTALLATION
A. Automatically end weld shear studs in accordance with AWS D1.1, Section 7.
B. Remove ceramic ferrules from anchors after welding.
C. Do not weld studs when temperature is below zero degrees F.
D. Do not weld studs when surface is wet with rain or snow.
3.04. FIELD QUALITY CONTROL
A. Deck: Inspect deck at welded connections. Reject connections where deck is not intact after welding and
where blow holes occurred.
B. Shear Studs:
