This article will give you an in-depth understanding of the world of H-beams

First, an introduction to H-beams.
H-beams, also known as I-beams, are economical profiles with more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-sectional shape is similar to the letter "H". The inner sides of the two outer edges of H-beams are straight and have no slope, which makes H-beams more convenient for welding and splicing and can effectively improve the quality of engineering and the safety of building structures.

Second, the specification representation method of H-beams.
The specification representation method of H-beams is usually in the form of height (h) × width (b) × thickness (d), for example, H100×100×6×8, indicating that the height of the H-beam is 100mm, the width is 100mm, the web thickness is 6mm, and the flange thickness is 8mm.

Third, the specification classification of H-beams.
H-beams have a wide variety of specifications, and they can be divided into multiple grades according to different standards. Generally speaking, H-beams can be divided into two types: ordinary and light. The ratio of the flange thickness to the web thickness of an ordinary H-beam is greater than 2.5; the ratio of the flange thickness to the web thickness of a light H-beam is less than or equal to 2.5.

Fourth, the selection of H-beam specifications.
When selecting the specifications of the H-beam, it is necessary to determine it according to the actual project needs and stress conditions. First, the height of the H-beam must be determined. Generally speaking, the height selection should be determined according to the span and load of the beam. Secondly, the width of the H-beam must be selected. The width selection is mainly determined according to the stress conditions of the beam and the needs of the building structure. Finally, the thickness of the H-beam must be selected. The thickness selection should be determined according to the stress conditions of the beam and the strength grade of the steel.

Fifth, the complete specifications of the H-beam.
Here are some common H-beam specifications for your reference: 1. H100×100×6×8. 2. H125×125×8×10. 3. H150×150×10×12. 4. H175×175×12×14. 5. H200×200×14×16. 6. H225×225×16×18. 7. H250×250×18×20. 8. H275×275×20×22. 9. H300×300×22×24. 10. H325×325×24×26. 11. H350×350×26×28. 12. H375×375×28×30. 13. H400×400×30×32. 14. H425×425×32×34. 15. H450×450×34×36.

Understanding the specifications of H-shaped steel and its selection method is of great significance for us in choosing suitable H-shaped steel in the fields of construction, bridges, machinery, etc. In practical applications, we need to select the appropriate H-shaped steel specifications according to the engineering needs and stress conditions to ensure the quality of the project and the safety of the building structure.
