EN 10025 S355JR/S355J0/S355J2 HEB(IPB) BEAM
EN 10025 is the European standard for non-alloy structural steel and fine-grained structural steel. S355JR, S355J0, and S355J2 are different grades of steel under this standard, and HEB (IPB) refers to a specific type of H-beam.
HEB is a wide flange H-beam, a European standard hot-rolled H-beam series. The flange width of HEB steel is relatively close to the web height, the cross-sectional shape is relatively regular, it has good bending and torsion resistance, and can effectively withstand loads in various directions.
