When comparing European standard I-shaped steel with its national counterpart, there are several key distinctions to consider. European standard I-shaped steel typically features a straight-legged design, which closely resembles H-shaped steel, whereas national standard I-shaped steel has a more diagonal leg configuration. This difference in shape can affect their respective applications and performance characteristics.
In terms of specifications and models, these two types of steel vary significantly. European standards often cover a wide range of sizes and configurations, with the most common being the IPE series, which consists of straight-legged profiles. On the other hand, the IPN series offers slanted legs but is less popular domestically due to smaller sizing options. For instance, IPE80 to IPE200 is commonly made from Q235B material, while larger sizes, such as IPE220 to IPE600, are primarily imported and made from materials like S355JR, S355J0, or S355J2.
The materials used also differ between the two standards. European standard I-shaped steel tends to have different carbon contents and chemical compositions compared to national standards, which can impact their strength and durability. These differences make them suitable for various industries, including machinery manufacturing, structural steel components, electrical and mechanical equipment, chemical processing, factory construction, bridges, building projects, highway foundations, petrochemicals, and even nuclear engineering.
For those looking into purchasing or using these steels, it's essential to understand that the availability of European standard IPE series is more widespread, especially in the straight-legged format. Slanted-legged profiles like IPN are harder to come by and usually only available in smaller dimensions. When dealing with larger sections, importing becomes necessary, and the choice of material shifts toward higher-grade options like S355JR, which offer enhanced properties.

In summary, while both types serve critical roles across multiple sectors, choosing between them depends largely on specific project requirements, budget constraints, and availability within your region. Understanding these nuances will help ensure you select the right product for your needs.
