EN S355J2 HEB220x220x9.5x16 h section steel

HEA200×190×6.5×10 structural h beam belongs to the HEA series (narrow flange type) in the European standard H-beam. It has a large section modulus and excellent bending stiffness. It is suitable for structural scenes with large bending moments.

Height (H): 200mm
Flange width (B): 190mm
Web thickness (t₁): 6.5mm
Flange thickness (t₂): 10mm
Theoretical weight: about 53.2 kg/m (need to be adjusted according to the actual material density)
