EN 10219 — Cold formed welded steel structural hollow sections
Scope
Cold-formed welded circular, square and rectangular hollow sections for structures: Part 1 technical delivery conditions (S235JRH, S275J0H/J2H, S355J0H/J2H/K2H, S420MH, S460MH, fine-grain and weathering variants), Part 2 tolerances, dimensions and sectional properties. Distinguished from EN 10210 (hot-finished) by lower corner radii tolerance class and cold-forming-related ductility limits.
