- Verified Note
- Source registered. Transcribed line-by-line from the ArcelorMittal European Sections catalogue (2023). Cross-checked on ingest (radius of gyration = sqrt(I/A); mass against catalogue summary p.42). Awaiting Cat's verified sign-off. Torsion (It) and warping (Iw) constants exist in the catalogue but are omitted here for consistency with the rest of the EU set.
400 IPN Overview
The 400 serial size group contains 1 section, ranging from 92.4 kg/m to 92.4 kg/m. All sections in this group share the same nominal depth and width but differ in web and flange thickness, which affects the weight and structural capacity.
Section properties are sourced from the Tata Steel Blue Book / SCI P363. For structural design to BS EN 1993-1-1 (Eurocode 3), use these properties with the appropriate partial factors from the UK National Annex.
