H-beam and I-beam

In construction and structural engineering, H-beam and I-beam are commonly used steels. They differ significantly in shape, performance and application. Choosing the right steel helps improve structural stability and life.

1. Appearance difference:

H-beam: wide flange, parallel inside and outside, uniform thickness, overall shape like the letter "H", large cross-section, strong bearing capacity.

I-beam: narrow flange, non-parallel inside and outside, gradually thinning thickness, shaped like the letter "I".

2 Application scenarios:

H-beam: commonly used in buildings, bridges and heavy mechanical structures that require large load-bearing capacity, suitable for occasions with large longitudinal and transverse loads.

I-beam: mostly used in light structures and secondary load-bearing structures, suitable for bearing unidirectional loads, such as beams, columns, etc.

3. Performance difference:

H-beam has a uniform cross-section, better force distribution and high stability.

I-beam has a single force direction and weak bending resistance.

Therefore, H-beams are more suitable for high-strength, heavy structures, while I-beams are suitable for light structures and general construction purposes.
