high-quality S355K2 steel H beams
Key Benefits of S355K2 High Quality Profiles Produced by GNEE
High Strength-to-Weight Ratio: Reduces material usage while maintaining structural integrity.
Weldability: Low carbon equivalent (CEV≤0.45) minimizes preheating requirements.
Durability: Resists fatigue and corrosion in harsh environments.
Certifications: CE marking and EN 10025-2 compliance ensure global quality standards.
S355K2 H Beam Manufacturing Process Offered by GNEE
Thermomechanical Rolling (TMCP): Billets are heated to 1000–1050°C and rolled with controlled cooling to refine the grain structure.
Optional Normalizing or Quenching+Tempering for enhanced properties.
Welding: Low hydrogen electrodes (e.g. AWS E7018), preheat (100–150°C).
Processing: Compatible with cold/hot bending and flame cutting.
Applications of S355K2 steel beams provided by GNEE
Civil Engineering: Bridges, high-rise buildings and industrial plants.
Marine and Offshore: Ship hulls, offshore platforms and cryogenic storage tanks.
Heavy Machinery: Mining equipment, crane booms and press frames.
