Steel Channel Weight Calculator

Enter the web height, flange width, wall thickness, and length of a steel C-channel section to get the weight in kg and lbs instantly.

Channel Dimensions

Vertical back wall of the C-section.

Horizontal projecting lip (top and bottom, assumed equal).

Uniform thickness of web and both flanges.

Formula Reference

Area = t × (H + 2F − 2t)
Weight = Area × Length × ρ

Where H = web height (m), F = flange width (m), t = wall thickness (m), L = length (m), ρ = density (kg/m³).

Summary

Enter the web height, flange width, wall thickness, and length of a steel C-channel section to get the weight in kg and lbs instantly.

How it works

  1. Enter the web height (H) — the vertical back wall of the channel.
  2. Enter the flange width (F) — the horizontal projecting lip on each side.
  3. Enter the wall thickness (t) — uniform thickness of the web and flanges.
  4. Enter the total bar length.
  5. Select the material from the dropdown, or choose Custom Density to enter your own value.
  6. Optionally set a quantity for multiple channel bars.
  7. Click Calculate — the tool applies Weight = t × (H + 2F − 2t) × Length × Density and shows results in kg and lbs.
