EN 10210 vs EN 10219 Standards
EN 10210 (Hot Finished)
- • Formed at high temperatures (normalized).
- • Stress-free structure with uniform grain size.
- • Tighter corner radii on square/rectangular hollows.
- • Preferred for dynamic, heavy-load bearing structures and offshore rigs.
EN 10219 (Cold Formed)
- • Formed at room temperature.
- • Internal stress remains in the corners (unless heat-treated post-forming).
- • Larger corner radii compared to hot finished.
- • Highly cost-effective for static building frameworks and general engineering.
