Euro-standard (EN) H-beams offer a wider variety of dimensions and specifications; their section heights and widths can be adjusted to meet specific project requirements. Their cross-sectional shapes are generally more flexible and can be customized according to specific design needs.

Chinese-standard (GB/T) H-beams have relatively fixed dimensions and specifications, offering a more limited range of choices. Common designations include 10#, 12#, 14#, and 16#, each corresponding to specific cross-sectional dimensions and shapes. Their cross-sectional shapes are generally uniform, lacking flexibility.

EN H-beams are typically manufactured from high-quality alloy steel, offering superior strength and toughness. GB/T H-beams are primarily made from ordinary carbon steel, resulting in relatively lower strength and toughness. These materials differ in terms of mechanical properties and chemical composition.

EN H-beams made of S235JR steel correspond to the GB/T Q235B;
EN H-beams made of S355J0 steel correspond to the GB/T Q355C;
EN H-beams made of S355J2 steel correspond to the GB/T Q355D;
EN H-beams made of S355JR steel correspond to the GB/T Q355B.
