Steel Angle Weight Calculator

Enter leg dimensions, thickness, and length of a steel angle (L-bar), choose material, and get the weight in kg and lbs instantly.

Angle Dimensions

Set equal to Leg A for equal-leg angles.

Formula Reference

Area = t × (A + B − t)
Weight = Area × Length × ρ

Where A = Leg A (m), B = Leg B (m), t = thickness (m), L = length (m), ρ = density (kg/m³).

Summary

Enter leg dimensions, thickness, and length of a steel angle (L-bar), choose material, and get the weight in kg and lbs instantly.

How it works

  1. Enter Leg A (the horizontal leg) in your preferred unit.
  2. Enter Leg B (the vertical leg) — use the same value as Leg A for equal-leg angles.
  3. Enter the thickness of the angle walls.
  4. Enter the total bar length.
  5. Select the material from the dropdown; choose "Custom Density" to enter your own value.
  6. Optionally enter a quantity for multiple angle bars.
  7. Click Calculate — the tool applies Weight = t × (A + B − t) × Length × Density and shows results in kg and lbs.
