What are the classifications of the HE series of European standard H-shaped steel?

As an important structural material in the fields of construction and engineering, the classification and material selection of the HE series of European standard H-shaped steel are crucial for ensuring the safety and stability of engineering projects. The following is a detailed introduction to the classification and materials of the HE series of European standard H-shaped steel:

1. Classification of the HE series of European standard H-shaped steel

The European Standard H-shaped steel HE series primarily includes various models such as HEA, HEB, and HEM, each with multiple specifications to accommodate different engineering requirements. Specifically:

HEA Type: This is a narrow-flange H-shaped steel with smaller cross-sectional dimensions and lighter weight, making it easier to transport and install. It is primarily used for beams and columns in building structures and bridge engineering, particularly suitable for承受ing large vertical and horizontal loads. The specific models in the HEA series include HEA100, HEA120, HEA140, HEA160, HEA180, HEA200, HEA220, etc., each with specific cross-sectional dimensions and weights.

HEB Type: This is a medium-flange H-shaped steel, with wider flanges compared to the HEA type, and moderate cross-sectional dimensions and weight. It is suitable for various building structures and bridge engineering projects requiring higher load-bearing capacity. The specific models of the HEB series include HEB100, HEB120, HEB140, HEB160, HEB180, HEB200, HEB220, etc.

HEM Type: This is a wide-flange H-shaped steel with flanges that are wider than those of the HEB type, and larger section dimensions and weight. It is suitable for building structures and bridge engineering projects that require the ability to withstand greater loads. Although the specific models of the HEM series are not mentioned in the reference article, its characteristics as a wide-flange H-shaped steel make it widely applicable in building and bridge engineering projects.

Additionally, the HEB-1 and HEM-1 types are improved versions of the HEB and HEM types, with increased cross-sectional dimensions and weight to enhance their load-bearing capacity. They are suitable for building structures and bridge engineering projects requiring higher load-bearing capacity.

2. Materials of the European Standard H-Beam HE Series

The European Standard H-Beam HE series typically uses high-strength low-alloy steel as its material to ensure superior performance and a long service life. These steels possess excellent plasticity and toughness, capable of meeting the demands of various complex structures. Specific materials include S235JR, S275JR, S355JR, and S355J2, among others. These materials comply with the European Standard EN 10034 and have obtained EU CE certification.
