400WC361

Welded Column · AS/NZS 3679.2 · Australia / New Zealand

400WC361 is a welded column 430.0 mm deep with a 400.0 mm wide flange, weighing 361.1 kg/m. The dimensions below are the published AS/NZS 3679.2 values; the drawing is generated from them.

Welded Columns extend the UC range the same way — three-plate sections for heavy column and transfer applications.

Derived section properties

Integrated from the section's exact plate outline — a welded section has square corners by construction, so nothing is approximated. For 400WC361 the computed area agrees to better than 0.01% and Ix to better than 0.01%. Where a value is also published, the published one above is the one to quote.
