Total Steel Tonnage
27.86 tons
≈ 5 elephants
How to Use This Calculator
- Enter the number of beams, their average weight in plf (e.g., W16x31 = 31 plf), and average span in ft.
- Enter the number of columns, their average weight in plf (e.g., W10x49 = 49 plf), and average height in ft.
- Read Total Beam Weight and Total Column Weight (both in tons) to build your steel takeoff.
- Use Total Steel Tonnage (tons) for budgeting and subcontractor bidding.
- Note Estimated Piece Count to plan erection sequencing and crane picks.
- Run the Structural Steel Cost calculator with the Total Steel Tonnage to estimate installed cost.
How the result changes with Number of Beams
| Number of Beams | Total Steel Tonnage |
|---|---|
| 1,000 | 531.86 tons |
| 3,500 | 1,844.36 tons |
| 6,500 | 3,419.36 tons |
| 9,000 | 4,731.86 tons |
What each input means

- Avg Beam Length
- Average beam span length in feet.
- Number of Columns
- Total count of steel columns.
- Avg Column Weight
- Average column weight in pounds per linear foot (e.g., W10x49 = 49 plf).
- Avg Column Height
- Average column height (floor-to-floor) in feet.
What each result means
- Total Beam Weight
- Combined weight of all beams in tons.
- Total Column Weight
- Combined weight of all columns in tons.
- Total Steel Tonnage
- Total structural steel tonnage (beams + columns).
- Total Weight
- Total steel weight in pounds.
- Estimated Piece Count
- Total number of individual steel pieces.
How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersNumber of Beams = 40, Avg Beam Weight = 35, Avg Beam Length = 30, Number of Columns = 20 = 6 input(s) provided
- Calculate Total Steel TonnageTotal Steel Tonnage = totalBeamWeightTons + totalColumnWeightTons27.86 = 27.86
- Calculate Total Beam WeightTotal Beam Weight = totalBeamWeightLbs / 200021 = 21
- Calculate Total Column WeightTotal Column Weight = totalColumnWeightLbs / 20006.86 = 6.86
