H steel is a new type of economic building steel. H type steel cross section shape is reasonable in economy, good mechanical properties, rolling each point on the extended section is uniform, small internal stress, compared with the ordinary beam, a section modulus, light weight, saving advantages of metal, can make the building structure to reduce 30-40%; and because of its inner and outer legs parallel leg end is right, assembled into components, welding, riveting work can save up to 25%. They are often used for large buildings, such as plant buildings, high-rise buildings, etc., which require great cutting capacity and good section stability, as well as bridges, ships, lifting appliances, equipment foundations, scaffolds, foundation piles, etc.
The main materials of H steel are Q235B, SM490, SS400, Q345, Q345B and so on.
1. High structural strength
Compared with the I-steel, the cross section modulus is large and the metal 10-15% can be saved when the loading conditions are the same.
2. design style is flexible and rich
In the case of the same beam height, the opening of the steel structure is 50% larger than that of the concrete structure, which makes the building layout more flexible.
3. light weight
Compared with the self weight of the concrete structure, the self weight of the structure is reduced, the internal force of the structural design is reduced, and the treatment requirement of the building structure foundation is low, the construction is simple and the cost is reduced.
4. the stability of the structure is high
The steel structure mainly based on hot rolled H steel is scientific and reasonable, with good plasticity and flexibility, and high structural stability. It is suitable for building structures bearing large vibration and impact loads, and has strong ability to resist natural disasters. It is especially suitable for building structures with many earthquakes.
5. easy to machine
It is easy to structure connection and installation, and easy to dismantle and reuse.
6. environmental protection
The use of H steel can effectively protect the environment. Compared with concrete, dry construction can be adopted, resulting in less noise and less dust. When the service life of building structure is expired, steel can be recovered.
7. The construction speed of the project is fast
Need small area, and suitable for all weather construction. The construction speed of the steel structure made with hot rolled H steel is about 2-3 times the construction speed of the concrete structure.
