HEA (European Standard Beam - Narrow Flange) steel has a series of standardized dimensions. The naming convention of HEA profiles is related to their height in millimeters. For example, HEA 100 has an approximate height of 100mm, with a flange width of 96mm, a web thickness of 5mm, and a flange thickness of 8mm. As the model number increases, the dimensions proportionally expand. HEA 200, for instance, has a height of 200mm, a flange width of 100mm, a web thickness of 6.5mm, and a flange thickness of 10mm. These precise dimensions are defined by European standards, which ensure consistency in production and easy integration in construction projects across different regions. The narrow - flange design of HEA steel makes it suitable for applications where space constraints are a concern while still providing adequate strength.
