Steel Sections Dimensions & Properties

The tables below are for initial reference only.    The links below provide much safer information... Corus is definitive for the UK and the spreadsheets provided by Technouk are excellent

Torsion Factors are only included in the tables below for the hollow sections.
For UB/UC/Joists/Channels and some Tee sections Torsion/Bucking/ or Warp Factors are available on webpages linked from Torsion
