420x216.5 WT Overview

The 420x216.5 serial size group contains 1 section, ranging from 217 kg/m to 217 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.
