Glass Channel Weight Calculator

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

Channel Dimensions

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

Vertical back wall of the C-section.

Uniform thickness of web and both flanges.

Formula Reference

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

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

Summary

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

How it works

  1. Enter the flange width (F) — the horizontal projecting lip at the top and bottom of the U-channel.
  2. Enter the web height (H) — the vertical back wall of the glass C-section.
  3. Enter the wall thickness (t) — uniform thickness applied to both the web and flanges.
  4. Enter the total channel length.
  5. Optionally override the glass density (default 2500 kg/m³) for specialty glass types.
  6. Optionally enter a quantity for multiple channel pieces.
  7. Click Calculate — the tool applies Weight = t × (H + 2F − 2t) × Length × Density and displays results in kg and lbs.
