Steel Section Weight Calculator
Use simple geometry and your own density value to estimate section mass. This is not a standard-section catalog or engineering assurance.
Section geometry
A QUICK WALKTHROUGH
How to use this tool
- Enter cross-sectional area, length, and material density.
- Choose consistent units and review the calculated mass estimate.
- Use the result as a planning estimate and verify dimensions, grade, coating, and actual material before relying on it.
Geometry only
This calculator uses a user-provided cross-sectional area, length, and density. It does not contain a steel section catalog and does not identify a standard profile, grade, alloy, coating, tolerances, or supplier product.
An estimate with explicit limits
Results assume a uniform section and the density you enter. They do not include joints, holes, welds, fittings, corrosion, paint, moisture, fabrication waste, packaging, or measurement error. Verify the result against current drawings and material records.

GOOD TO KNOW
Common questions
Does it know standard steel profiles?
No. Enter the cross-sectional area yourself; no incomplete section catalog is bundled.
Is this suitable for structural design?
It is a mass estimate only. Confirm design, material, tolerances, and safety requirements with appropriately qualified professionals.
What density should I enter?
Use a density from your material documentation or other trusted source, with units consistent with the selected inputs.
