Aluminum Channel Weight Calculator
Enter web height, flange width, wall thickness, and length of an aluminum C-channel 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
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 web height, flange width, wall thickness, and length of an aluminum C-channel to get the weight in kg and lbs instantly.
How it works
- Enter the web height (H) — the vertical back wall of the aluminum C-section.
- Enter the flange width (F) — the horizontal projecting lip at the top and bottom.
- Enter the wall thickness (t) — uniform thickness of both the web and flanges.
- Enter the total bar length.
- Select the aluminum alloy from the dropdown, or choose Custom Density for a user-defined value.
- Optionally enter a quantity for multiple channel bars.
- Click Calculate — the tool applies Weight = t × (H + 2F − 2t) × Length × Density and displays results in kg and lbs.
Use cases
- Estimating aluminum frame weight for architectural and structural projects.
- Calculating shipping and freight weight for aluminum extrusion orders.
- Bill of materials (BOM) preparation for aluminum fabrication shops.
- Comparing channel sizes to find the lightest design that meets load requirements.
- Verifying theoretical weight against supplier mill certificates.
- Checking rigging and lifting load limits before hoisting aluminum sections.
- Cost estimation when pricing aluminum by weight.
- Academic and exam calculations for lightweight structures and aerospace components.
