I-beams are a type of structural steel widely used in the construction of various infrastructure projects, including frame structures, bridges, and tunnels. Their unique shape and strength make them an indispensable part of modern architecture. The topic of European standard I-beam designations involves how a standardized set of codes is used to precisely describe different models and specifications of European standard I-beams.

Common European standard I-beam designations include IPE/HEA, HEB, and HEM. IPE I-beams belong to the European standard, with clearly defined cross-sectional dimensions, shape, and weight. This type of steel has wider flanges and a slight inward slope, which allows it to better distribute pressure under load.

The IPN180 designation for I-beams indicates the height of the I-beam in millimeters. In contrast, European standard I-beams use different marking methods such as HEA, HEB, and IPE, indicating different dimensions and performance requirements. HEA type I-beams are generally taller and suitable for bearing larger loads; while IPE type I-beams are standard and suitable for general structures.
