Total Deck Area (w/ 3% Waste)10,300 sq ft
Shear Stud Count800
Pour Stop440 LF
Total Deck Weight22,660 lbs
Side Lap Fasteners1,725
How to Use This Calculator
  1. Enter the total floor area in sq ft to be covered with metal deck.
  2. Select the deck type: 1=1.5 in composite, 2=2 in composite, or 3=3 in roof deck.
  3. Choose the deck gauge (16 heaviest to 22 lightest) and the side lap fastener type.
  4. Read Number of Deck Sheets (at 36 in coverage width) to place your material order.
  5. For composite deck, note Shear Stud Count and coordinate with the structural engineer's composite design.
  6. Use Pour Stop (LF) for edge forming and Total Deck Weight (lbs) for structural dead load.

What each input means

Floor Area
Total floor area to be covered with metal deck.
Deck Type
Select metal deck profile type
Deck Gauge
Steel gauge thickness (16 = heaviest, 22 = lightest).
Side Lap Type
Select side lap connection method

What each result means

Number of Deck Sheets
Total deck sheets needed (36" coverage width, standard lengths).
Total Deck Area (w/ 3% Waste)
Floor area plus 3% waste factor.
Shear Stud Count
Estimated headed shear studs (1 per rib per beam, composite only).
Pour Stop
Linear feet of pour stop at slab edges and openings.
Total Deck Weight
Estimated weight of metal deck based on gauge.
Side Lap Fasteners
Approximate side lap fastener count.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Floor Area = 10000, Deck Type = 1, Deck Gauge = 20, Side Lap Type = 1 = 4 input(s) provided
  2. Calculate Number of Deck Sheets
    Number of Deck Sheets
    115 = 115
  3. Calculate Total Deck Area
    Total Deck Area = floorArea * 1.03
    10300 = 10300
  4. Calculate Shear Stud Count
    Shear Stud Count
    800 = 800
