Use this structural steel calculator to turn field quantities and planning assumptions into a clear working estimate. Adjust the inputs to match the drawings, crew records, supplier data, or equipment cycle observations for your project. The supporting results make it easier to check the main figure and compare alternatives before committing labor, material, or equipment.
The main result is a planning estimate for structural steel. It is most reliable when inputs come from current drawings, measured production, or supplier data rather than broad averages.
Construction conditions, access, detailing, weather, sequencing, and local practice can change actual outcomes. Confirm procurement and schedule decisions with the project team.
36 members averaging 24 ft at 31 lb/ft weigh 26,784 lb. After 1,800 lb of plates and 3% waste, the order estimate is 29,441.5 lb.
Member count, average length, and section weight are multiplied, then connection steel and waste are added.
No. Add them separately unless their weight is already included in the connection-plate entry.
For a rough estimate, yes. For procurement, calculate each section group separately and combine the totals.
Use the applicable steel shape table, design schedule, or supplier data for pounds per foot.
No. It is a planning estimate and should be reconciled with approved shop drawings before ordering.
