H-beams are an economical section steel with superior mechanical properties, developed by optimizing the I-beam section, and are named for their cross-section shape that resembles the English letter "H". Their characteristics are as follows:

◆ Wide flange width, high lateral stiffness.

◆High bending strength, about 5%-10% stronger than I-beams.

◆The two surfaces of the flange are parallel to each other, making connections, processing, and installation easy.

Compared to welded I-beams, they offer higher precision, less residual stress, and do not require expensive welding materials or weld inspections, saving about 30% in steel structure manufacturing.

Under the same cross-sectional load, hot-rolled H-steel structures are 15%-20% lighter than traditional steel structures.

Compared to concrete structures, hot-rolled H-shaped steel structures can increase the usable area by 6% and reduce the structural weight by 20% to 30%, thereby decreasing the internal forces in structural design.

◆H-beams can be processed into T-beams, and honeycomb beams can be combined to form various cross-sectional shapes, meeting engineering design and manufacturing requirements.

H-beams are categorized into hot-rolled H-beams and welded H-beams (H), with hot-rolled H-beams further divided into wide-flange H-beams (HW), medium-flange H-beams (HM), and narrow-flange H-beams (HN).

HW is essentially equal in height to the flange width; mainly used for steel core columns in reinforced concrete frame structures, also known as rigid steel columns; primarily used for columns in steel structures.

HM is a type of steel with a height to flange width ratio of approximately 1.33 to 1.75, primarily used in steel structures: as columns in steel frame structures supporting dynamic loads and as beams in frame structures; for example: equipment platforms.

HN beams have a height to flange width ratio of 2 or more, primarily used for beams; the application of I-beams is equivalent to that of HN beams.

The main materials for H-shaped steel include Q235B, SM490, SS400, Q345, and Q345B.

H-beams are primarily used for beam and column components in industrial and civil structures.
