What is a H Beam?
H-Beam, as the name suggests, is rolled steel joist (RSJ) with the cross section in the form of the capital letter H. It is the
one of the most common and widely used structural steel member used in both residential and commercial building projects.
Because of its superior mechanical properties and better strength to weight ratio, they make for the preferred choice of material for mezzanines, bridges, and platforms. Plus they have wide flanges which are commonly used in residential building projects.
Hot rolled H beam
Billet after finishing and weighing, into the heating furnace.Then high pressure phosphorus removal, into the universal roughing mill rolling, and finally into the universal finishing mill forming.
Welded beam
Welded light gauge steel H section is H-steel manufactured
continuously from a hot-rolled steel strip by high-frequency resistance welding. It features thinner plate thickness and more accurate cross-sectional dimensions compared to a hot-rolled H section.

Difference of H beam and I beam
1. The side length of I-beam is small and the height is large, so it can only bear unidirectional force. The H-shaped steel channel is deep and thick, and can withstand forces in two directions.
2. I-beams can only be used for beams, while H-beams can be used for structural load-bearing columns.
3. H-beam is an economical cross-section steel with better mechanical properties than I-beam. It is named because the shape of the cross-section is the same as the English letter "H". The flanges of hot-rolled H-beams are wider than I-beams, with greater lateral rigidity and stronger bending resistance. Under the same specifications, H-beams are lighter in weight than I-beams.
4. I-steel flanges are variable-wearing surfaces that are thicker on the web and thinner on the outside; H-beam flanges are equal-wearing surfaces.
Regardless of whether the I-shaped steel is ordinary or light, because the cross-section size is relatively high and narrow, the moment of inertia of the two main sleeves of the cross-section is quite different. Therefore, it can generally only be used directly in the plane of its web. Bending members or combine them into lattice-type force-bearing members. It is not suitable to use axial compression members or members that are perpendicular to the plane of the web and have bending, which makes the application range very limited.
5. H-shaped steel is a high-efficiency and economical cutting profile (others include cold-formed thin-walled steel, profiled steel, etc.). Due to the reasonable cross-sectional shape, they can make the steel more effective and improve the cutting capacity. Different from ordinary I-shaped steel, the flange of h-shaped steel has been widened, and the inner and outer surfaces are usually parallel, which can facilitate the connection with high-strength bolts and other components. Its size constitutes a reasonable series, and the models are complete, which is convenient for design and selection. (Except for I-shaped steel for crane beams)
