American standard H-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, as American standard H-shaped steel has significant limitations in its application range.

H-shaped steel belongs to efficient and economical cutting profiles (including cold-formed thin-walled steel, profiled steel plates, etc.). Due to their reasonable cross-sectional shape, they can enhance the efficiency of the steel and improve its load-bearing capacity.

Unlike ordinary I-beams, the flange of H-beams has been widened, and the inner and outer surfaces are usually parallel, making it easier to connect with high-strength bolts and other components. Its size composition series is reasonable, and the models are complete, making it easy to design and choose.
