Channel (C-Section) Weight Calculator
ISMC-style channel weight from web, flanges and thicknesses.
ISMC 100 ≈ 9.2–9.6 kg/m depending on taper assumptions — rolled flanges taper, so catalogue numbers use the mean flange thickness as here.
Formula
Channel (C-Section) Weight Calculator is a free channel weight for structural engineers, fabricators and site engineers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Channel (C-Section) Weight Calculator
ISMC-style channel weight from web, flanges and thicknesses. The calculation implements A = h·t_w + 2(b−t_w)·t_f; W = A×0.00785 (IS 808 channel tables). ISMC 100 ≈ 9.2–9.6 kg/m depending on taper assumptions — rolled flanges taper, so catalogue numbers use the mean flange thickness as here.

Frequently asked questions
What formula does the Channel (C-Section) Weight Calculator use?+
It computes A = h·t_w + 2(b−t_w)·t_f; W = A×0.00785, per IS 808 channel tables. The formula is displayed under the result.
What should I keep in mind when using this calculator?+
ISMC 100 ≈ 9.2–9.6 kg/m depending on taper assumptions — rolled flanges taper, so catalogue numbers use the mean flange thickness as here.
Can I use this for real structural design?+
It implements the exact textbook/code formula cited below the result and is ideal for sizing, checking and learning. Final designs should be verified by a qualified engineer against the full code with all load cases.
Is the Channel (C-Section) Weight Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
