What is the h channel steel?

H channel steel is a type of steel with an H-shaped cross-section, usually made by hot rolling or cold bending. Its cross-section presents the shape of the letter "H", hence the name.

H channel steel has the advantages of strong bending resistance in all directions, simple construction, cost-saving, and light structural weight, and has been widely used.

Features of H channel steel

1. Stable cross-sectional size and shape: The cross-sectional size and shape of the H channel steel are very stable, which gives it excellent bearing capacity and stability.

2. High strength and large bearing capacity: H channel steel has a large cross-sectional area, has high bending resistance and bearing capacity, and is suitable for structures with large spans and large loads.

3. Save steel: Compared with ordinary steel, H channel steel has a large cross-sectional area, which can use less steel under the same bearing capacity and reduce costs.

4. Good weldability: H channel steel can be easily welded and connected, suitable for lap joints and connections of various structures.

5. Wide range of uses: H channel steel is widely used in various building structures and projects, such as factory buildings, bridges, towers, ships, mechanical equipment, etc.

6. Convenient construction: The cross-sectional dimensions of H-shaped steel are standardized, the processing and forming are simple, and the construction is convenient and fast.

Classification of H-shaped steel:

Classification by cross-sectional shape:

1. Standard H-shaped steel: The cross-sectional shape is the letter "H", with two identical or similar horizontal wings and a vertical middle part.

2. Extra-wide wing H-shaped steel: The flange width is larger than that of standard H-shaped steel, used to bear greater loads.

3. Narrow wing H-shaped steel: The flange width is narrower than that of standard H-shaped steel, suitable for places with limited space.

Classification by specifications and sizes:

1. Standard specification H-shaped steel: H-shaped steel is produced according to the specifications and sizes formulated by national or industry standards.

2. Non-standard specification H-shaped steel: H-shaped steel of non-standard sizes and specifications manufactured according to specific needs.

Classification by use:

1. Structural H-beam: used in structural engineering such as buildings, bridges, towers, mechanical equipment, etc.

2. H-beam for bridges: used in the construction of bridge structures, usually with specific design requirements and specifications.

3. H-beam for ships: structural steel materials used in hulls, decks, masts, etc. in ship construction.

Classification by manufacturing process:

1. Hot-rolled H-beam: H-beam made by hot rolling.

2. Cold-bent H-beam: H-beam made by cold bending, usually used in structural engineering with special requirements.
