Channel Weight Calculator
Enter millimetre dimensions, length, and steel density to estimate cross-sectional area and mass.
A QUICK WALKTHROUGH
How to use this tool
- Enter positive finite dimensions.
- Choose Calculate.
- Review area, mass per metre, and total mass.
Approximation
A = d×tw + 2×(b−tw)×tf mm²; kg/m = A×10⁻⁶×ρ; mass = kg/m×length.
Scope
This supports only a straight-edge thin-wall approximation. It ignores fillets and tapered flanges and is not a design guarantee.
Validation
Values must be positive finite numbers; depth must exceed twice flange thickness and width must exceed web thickness.
