S275JR S355J2 HEA200x190x6.5x10 H beam supplier

HEA200×190×6.5×10 beam steel belongs to the HEA series (narrow flange type) in the European standard H-shaped steel. The specific dimensions are:
Height (H): 200mm
Flange width (B): 190mm
Web thickness (t₁): 6.5mm
Flange thickness (t₂): 10mm

Weight and section characteristics
The theoretical weight is about 53.2 kg/m (need to be adjusted according to the actual material density); the section modulus is large and the bending stiffness is excellent, which is suitable for structural scenes with large bending moments.
