Is German standard H-beam the same as European standard H-beam? What are the differences?

The flange of I-shaped steel has a variable cross-section with a thick web plate and a thin outer surface; The flange of H-shaped steel is of equal cross-section

HW HM HN H is the general term for H-shaped steel, which is welded; HW HM HN is hot-rolled

HW is the height and flange width of H-shaped steel that are basically equal; Mainly used for steel core columns in reinforced concrete frame structures, also known as rigid steel columns; Mainly used for columns in steel structures

HM is an H-shaped steel with a height to flange width ratio of approximately 1.33 to 1.75, mainly used in steel structures as steel frame columns and as frame beams in frame structures under dynamic loads; For example: device platform

HN refers to the ratio of H-shaped steel height to flange width greater than or equal to 2, mainly used for beams; The use of I-shaped steel is equivalent to that of HN shaped steel;

I-shaped steel, whether ordinary or lightweight, has relatively high and narrow cross-sectional dimensions, resulting in a significant difference in the moment of inertia between the two main sleeves of the cross-section. Therefore, it can generally only be directly used for components that are bent in the plane of its web or to form a lattice load-bearing component. It is not suitable to use axial compression components or components with bending perpendicular to the web plane, which limits their application range.

The national standard for hot-rolled H-beams in China (GB/T11263-1998) divides H-beams into three categories: narrow flange, wide flange, and steel pile, with codes hz, hk, and hu, respectively. Narrow flange H-shaped steel is suitable for beams or compression bending components, while wide flange H-shaped steel and H-shaped steel piles are suitable for axial compression or compression bending components. Compared with H-beam, I-beam is not as good as H-beam in terms of w, ix, and iy under equal weight conditions
