How to Use This Calculator
  1. Enter the count of each miscellaneous metal item: handrail sections (10 LF each), stair flights, embed plates, and loose lintels.
  2. Enter the total building area in sq ft — this calculates the misc metals intensity ratio (lbs/sq ft) for benchmarking.
  3. Read Total Misc Metals (tons) as the primary takeoff value for bidding.
  4. Review individual weight outputs (Handrail Weight, Stair Weight, Embed Plate Weight, Lintel Weight) to verify scope.
  5. Use Estimated Cost for budget purposes based on $5,000/ton installed rate.
  6. Compare Intensity Ratio (lbs/sq ft) against industry norms: 0.3–0.8 lbs/sq ft is typical for commercial buildings.

What each input means

Handrail Sections
Number of 10 LF handrail sections (pipe rail with posts and kick plate).
Stair Flights
Number of steel stair flights (one level per flight, including landing).
Embed Plates
Number of embed plates (average 8"x8" to 12"x12" with headed studs).
Loose Lintels
Number of loose steel angle lintels over masonry openings.
Total Building Area
Total building floor area for intensity ratio.

What each result means

Handrail Weight
Total weight of handrail assemblies.
Stair Weight
Total weight of steel stair flights.
Embed Plate Weight
Total weight of embed plates.
Lintel Weight
Total weight of loose lintels.
Total Misc Metals
Combined miscellaneous metals tonnage.
Total Weight
Total miscellaneous metals weight in pounds.
Estimated Cost
Estimated installed cost at $5,000/ton.
Intensity Ratio
Misc metals weight per square foot of building area.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Handrail Sections = 10, Stair Flights = 4, Embed Plates = 25, Loose Lintels = 30 = 5 input(s) provided
  2. Calculate Total Misc Metals
    Total Misc Metals = totalWeightLbs / 2000
    3.09 = 3.09
  3. Calculate Handrail Weight
    Handrail Weight = handrailWeightLbs / 2000
    0.375 = 0.375
  4. Calculate Stair Weight
    Stair Weight = stairWeightLbs / 2000
    2 = 2
