There are significant differences between I-beam and H-beam in many aspects. The following are the main differences between them:

1. Properties and appearance

I-beam: I-shaped in cross-section, it is a long steel material. According to its characteristics, I-beams can be divided into three categories: ordinary type, wide flange type and light type. Its cross-sectional design makes it excellent in withstanding direct pressure and resistant to tension, but its torsional resistance is relatively poor.

H-shaped steel: The cross-sectional shape is similar to the letter "H". It is an economical steel with a more optimized layout, more reasonable strength and weight. The outer and inner edges of both sides of the H-shaped steel are straight and have no slope, which makes it easier to weld and splice than the I-beam. In addition, H-shaped steel can be divided into large, medium and small sizes according to size.

2.Performance

I-beam: It has strong compression resistance and bending resistance and can withstand large pressure and bending loads. Therefore, it is often used in beams, columns, stairs and platforms in building structures, as well as in bridges and machinery manufacturing. Its chemical composition is stable and safe and reliable to use.

H-beam: It is better than I-beam in terms of rigidity and stability, and its bending resistance is also particularly good. Its flange is wide, lateral stiffness is large, and its bending resistance is about 5% to 10% higher than that of I-beam. H-shaped steel has a large section modulus and can save 10% to 15% of metal under the same load-bearing conditions. In addition, H-shaped steel also has good plasticity and flexibility, high structural stability, and is suitable for building structures that can withstand large vibration and impact loads.

3.Application fields

I-beam: widely used in building structures, bridges, supports, machinery manufacturing, aerospace and other fields. Its high strength and resistance to compression make it an indispensable material in these fields.

H-shaped steel: In addition to being suitable for industrial building structures and civil building structures, it is also widely used in underground construction projects, highway baffle supports, industrial equipment structures such as petrochemical and electric power, long-span steel bridge components, ships, and machinery manufacturing frame structures. As well as trains, cars, tractor beam supports and other fields. The wide application of H-shaped steel benefits from its excellent mechanical properties and superior usability.

4.Production process

I-beam: generally produced through hot rolling process, its production process is relatively simple.

H-shaped steel: not only can be produced by hot rolling, but can also be processed through welding and other processes. This makes H-shaped steel more flexible and diverse in production technology.
