EN 10219 Standard Technical Specifications

Material Grade Requirements

Ordinary non-alloy steel: Min yield strength ≥235MPa (Representative grade: S235JR)

Weather-resistant fine-grain steel: Min yield strength ≥355MPa (Representative grade: S355J2H)

High-strength structural steel: Tensile strength 530–720MPa (Representative grade: S460MH)

Mandatory Mechanical Performance

S355J2H yield strength ≥355MPa; S460MH yield strength ≥460MPa

Minimum elongation rate: 22%

Impact toughness: ≥27J at -20°C

Standardized welding procedures to guarantee weld integrity

Forming & Surface Special Rules

Forming process: Produced only by cold forming + welding; post-forming heat treatment is prohibited

Anti-corrosion requirement: Weathering steel needs complete anti-corrosion testing; galvanized coating weight controlled within 40–600g/ square meter

Main Application Scenarios

With high strength, precise dimensional accuracy and stable structural performance, this pipe series is widely used for load-bearing and anti-impact projects:

Building Steel Structure

Large-span factory, warehouse, office and shopping mall load-bearing columns & beams

Stair railings, equipment platform support frames

Hot-dip galvanization available for long-term outdoor service

New Energy Wind Power

Internal structural components of wind turbine towers

Stable performance under extreme -40°C low temperature, impact toughness ≥34J, effectively avoiding low-temperature brittle fracture

Custom grade selection can be made according to project priorities: cost control, easy machining, low-temperature toughness, corrosion resistance, impact resistance, fatigue resistance and lightweight demand.
