Selection checks

Check nominal wall thickness, design thickness, corner radius assumptions, and welding process before final design.
Closed sections can be excellent for torsion, but connection detailing and internal corrosion access need review.
For procurement, confirm whether the supplier offers hot-finished, cold-formed, galvanised, or painted options.
