First, the implementation of different standards, the implementation of the European standard H-beam steel standard EN10034-1993 EN10025-3-2004 and the implementation of the national standard is GB/T706-2016;
Second, the material difference, the two materials are not the same material S235JR European standard H-beam steel corresponding to the national standard model steel Q235B European standard H-beam steel material S355J0 corresponding to the national standard model steel Q355C European standard H-beam steel material S355J2 corresponding to the national standard model steel Q355D European H-beam steel material S355JR corresponding to the national standard model steel Q355B European H-beam steel material S355JR corresponding to the national standard model steel Q355D European H-beam steel material S355JR corresponding to the national standard model steel Q355B Q355B.
Third, each model represents the corresponding model of the cross-section size and geometry European standard H-beam steel can be further divided into a variety of categories according to different materials, such as ordinary carbon structural steel, low alloy high-strength steel, hot-rolled welded steel, etc. Different models and materials of the European standard H-beam steel has a different load-bearing capacity bending resistance and corrosion resistance.
