Hot rolled H-beam features

The hot-rolled H-beam reasonably distributes the aspect ratio of the section size according to different uses, and has excellent mechanical properties and superior performance.

★Structural strength is high. Compared with I-beam, the section modulus is large, and the metal can be saved by 10-15% under the same bearing conditions.

★The design style is flexible and rich. With the same beam height, the bay of the steel structure can be 50% larger than the bay of the concrete structure, thus making the building arrangement more flexible.

★The structure is light in weight. Compared with the self-weight of the concrete structure, it is lighter, and the reduction of the self-weight of the structure reduces the internal force of the structural design, which can make the basic treatment requirements of the building structure low, the construction is simple, and the cost is reduced.

★Steel structure mainly made of hot-rolled H-beam, its structure is scientific and reasonable, good plasticity and flexibility, high structural stability, suitable for building structures with large vibration and impact loads, strong resistance to natural disasters, especially suitable for some Building structures in multiple earthquake zones. According to statistics, among the devastating earthquakes of magnitude 7 or above in the world, the steel structure buildings mainly made of H-beam suffered the least damage.

★Increase the effective use area of the structure. Compared with the concrete structure, the cross-sectional area of the steel structure column is small, which can increase the effective use area of the building. Depending on the different forms of the building, the effective use area can be increased by 4-6%.

★Compared with welded H-beam, it can obviously save labor and material, reduce the consumption of raw materials, energy and labor, low residual stress, and good appearance and surface quality.

★Easy for machining, structural connection and installation, and easy to dismantle and reuse.

★The use of H-beam can effectively protect the environment, which is reflected in three aspects: first, compared with concrete, dry construction can be used, which produces less noise and less dust; The damage to land resources is small, and in addition, the amount of concrete is greatly reduced, and the amount of rock excavation is reduced, which is conducive to the protection of the ecological environment; third, after the service life of the building structure expires and the structure is demolished, the amount of solid waste generated is small, and the recycling value of scrap steel resources high.
