Metals Weight Calculator


Theoretical weight from published density and the dimensions you enter. Estimates use actual pipe dimensions and material-specific sheet gauges.

Two legs the same. The corner square is counted once, not twice.

One density for the whole family. Grade moves steel density by well under half a percent, and the structural world has standardised on 490 lb/ft3.

0.2836 lb/in³

Weight is always shown in both pounds and kilograms.

Two legs meeting at a right angle. A is the first leg, B the second, and t the thickness of both. The corner square where the legs meet is counted once, not twice.

Density source: AISC basis: structural steel at 490 lb/ft3 (0.28356 lb/in3) Reproduces the AISC tabulated shape weights from the tabulated areas.

What this number does and does not include (2)
  • Theoretical weight This is a calculated weight from published density and the dimensions you entered. Actual weight varies with mill tolerance, and Benner quotes, invoices and ships against the book weight for the commercial size.
  • Rolled section, geometry only Hot-rolled sections have fillets where the web meets the flange and radii at the toes. This outline omits those features, so the calculated weight can differ from the published section weight. Measured against AISC tables: beams -1.0% to -1.3%, channels -1.2% to -1.5%, hot-rolled steel angle within about +/-0.7%. Source: AISC L / C / W property tables

Calculated weights are theoretical. Actual weight varies with mill tolerance, and Benner quotes, invoices and ships against the book weight for the commercial size. Densities, gauge tables and pipe schedules each cite their source in the notes above.
