Specification

1. Standard
Complies with EN 10210-1:2006 (Hot-finished structural hollow sections)
Supplementary requirements per EN 10219-2 (cold-formed counterparts)

2. Dimensional Specifications
Size Range:

Circular (CHS): 21.3mm to 711mm OD
Wall Thickness: 2.0mm to 40mm
Standard Lengths: 6m, 12m, or custom-cut

3. Performance Advantages
Seamless integrity: No weld seams, ideal for critical load-bearing structures
Superior toughness: J2H grade resists brittle fracture at -20°C
Excellent machinability: Balanced carbon content (0.22% max)
Weldability: Low CEV (≤0.45) allows arc/MIG/TIG welding without preheat

4. Quality Assurance
Ultrasonic testing (UT): Mandatory per EN 10210
Chemical analysis: Spectrometry for precise element control
Dimensional checks: Laser gauging for OD/wall consistency

5. Application Scenarios
Construction: Stadiums, bridges, high-rise buildings (EN 1090-2 compliant)
Mechanical engineering: Crane booms, hydraulic cylinders
Transportation: Chassis components, roll cages
Infrastructure: Offshore wind turbine towers

6. Packaging and Delivery
Bundling: Hexagonal bundles with steel straps (anti-scratch plastic edge guards)
Anti-corrosion: VCI paper or light oil coating (indoor storage)
