Overview of EN 10219 Standard
EN 10219 is the European standard for cold formed welded structural hollow sections. It is widely used in construction and mechanical engineering fields.
Product scope: Cold-bending welded round, square and rectangular hollow sections, not seamless pipes.
Standard structure:EN 10219-1: Technical delivery conditions;EN 10219-2: Dimensions, tolerances and section properties;EN 10219-3: Stainless steel hollow sections.
Material features: Carbon steel and fine grain steel with excellent weldability; some grades guarantee low-temperature impact resistance.
Manufacturing process: Cold forming + high-frequency welding; weld seam full NDT inspection, no overall heat treatment required.
Certification: 3.1 / 3.2 inspection certificates supplied; CE marking is required for EU market export.
Applications: Building steel structures, support frames, guardrails, bridges and mechanical engineering constructions.
EN 10219 Common Grade Selection Chart
表格
| Steel Grade | Key Feature | Service Environment | Application Recommendation |
|---|---|---|---|
| S235JRH | Normal strength, room temperature use | Indoor & light load | Simple workshops, fences, light supports (cost-effective choice) |
| S275J2H | Medium strength, -20℃ impact resistance | Outdoor general climate | Common building structures, medium machine frames |
| S355J2H | High strength, excellent low-temperature toughness | Cold outdoor & heavy load | Bridges, large factories, heavy-duty frames (best-selling grade) |
