The difference between I-beam and H-beam

The differences between I-beams and H-beams mainly lie in their properties, classifications, areas of use and characteristics.

Nature: The cross section of the I-beam is a long steel with an I shape, while the H-beam is an economical steel with a more optimized size layout, more reasonable strength and weight, and its cross section is symmetrical like the letter "H".

Classification: I-beams are divided into three categories, namely ordinary, wide flange and light. H-beams are divided into large, medium and small sizes according to their sizes.

Field of use: I-beams can be used in various building structures, bridges, brackets and machinery. H-beams are more suitable for industrial building structures, civil building structures, underground construction projects and highway baffle brackets.

Features: There is no slope on the inner and outer sides of the two sides of the H-beam, and they are all straight, which makes welding and splicing simpler than I-beams, which can effectively save a lot of materials and shorten construction time. The cross section of the I-beam is very good at resisting direct pressure and is resistant to tension, but the torsion resistance is poor because the wing is too narrow.

In addition, there are also differences in shape between the two. The flange of the I-beam is a variable section, thick near the web and thin outside; the flange of the H-beam is a constant section. With the same amount of steel, H-beam can withstand greater rigidity and stability than I-beam, and its torsion and bending resistance are better than I-beam.

In general, I-beam and H-beam each have their own characteristics and applicable scenarios. The choice of which steel should be determined according to specific needs and conditions.
