When comparing European standard I-shaped steel to its national counterpart, there are several key differences that set them apart. First off, European standard I-shaped steel features a design where the legs are straight, resembling H-shaped steel, whereas national standard I-shaped steel typically has legs that are slanted. This structural difference can impact how they're used in various applications.
Another distinction lies in their specifications and models. European standards often cover a broader range of sizes and configurations, which can cater to more diverse needs. Additionally, the materials and grades used in these two types of steel vary significantly. For instance, the carbon content and overall chemical composition can differ, affecting factors like strength and durability.
European standard I-shaped steel comes in different series. The IPE series is known for its straight legs, while the IPN series features slanted legs. The IPE series, particularly with smaller sizes like IPE80 to IPE200, commonly uses Q235B as its material. Larger sizes, ranging from IPE220 to IPE600, are usually imported and primarily made from materials such as S355JR, S355J0, or S355J2. These larger sizes are less common in domestic production.
In terms of application, both types of steel find use in an array of industries including machinery manufacturing, steel structure construction, electromechanical equipment, chemical processing, industrial facilities, bridge building, construction projects, highway foundations, petrochemicals, and even nuclear engineering.
While the IPN series with its slanted legs may not be as popular domestically, it still holds value in certain specialized applications. The IPE series, on the other hand, remains widely available and favored for its versatility and performance. Whether you're working on a small-scale project or a large infrastructure development, understanding these differences can help ensure you choose the right type of steel for your needs.
