H Beams
H Beams is an economical section and efficient section with more optimized cross-sectional area allocation and more reasonable weight-to-weight ratio. It is named because its section is the same as the English letter "H". Because all parts of the H-beam are arranged at right angles, the H-beam has the advantages of strong bending resistance, simple construction, cost saving and light weight in all directions, and has been widely used.

H-beam is a new type of economic construction steel. The shape of the H Beams section is economical and reasonable, and the mechanical properties are good. The points on the section are evenly extended and the internal stress is small during rolling. Compared with ordinary I-beams, it has the advantages of large section modulus, light weight, and metal saving. The structure is reduced by 30-40%; and because the inside and outside of the legs are parallel, and the leg ends are at right angles, the assembly and assembly into components can save welding and riveting workload by up to 25%. It is often used in large buildings (such as factory buildings, high-rise buildings, etc.) that require large load-bearing capacity and good cross-section stability, as well as bridges, ships, lifting and transportation machinery, equipment foundations, supports, and foundation piles.

H-beam is economical cross-section steel with better cross-section mechanical properties, which is optimized and developed from I-beams. In particular, the cross-section is named after the English letter "H".

HGB H beams characteristics are as follows:
1.Wide flange and large lateral stiffness.
2.Strong bending resistance, about 5% -10% than I-beam.
3. The two surfaces of the flange are parallel to each other, which makes connection, processing, and installation easy.
4. Compared with welding I-beams, it has low cost, high accuracy, and small residual stress. It does not require expensive welding materials and weld seam detection, which saves about 30% of the cost of manufacturing steel structures.
5. Under the same cross-section load, the hot-rolled H steel structure is 15% -20% lighter than the traditional steel structure.
6. Compared with the concrete structure, the hot-rolled H steel structure can increase the use area by 6%, while the structure's own weight is reduced by 20% -30%, which reduces the internal force of the structural design.
7.H-beams can be processed into T-beams, and honeycomb beams can be combined to form various cross-section forms, which greatly meets engineering design and production requirements.

Classification of H-beams

There are two types of hot-rolled H-beams and welded H-beams (H). Hot-rolled H-beams are divided into wide flange H-beams (HW), middle flange H-beams (HM) and narrow flange H-beams (HN) .

Application of H-beams

1. Mainly used in beams and columns in industrial and civil structures.
2. Steel structure load-bearing support for industrial structures
3. Steel piles and supporting structures for underground engineering
4. Petrochemical and electric power industry equipment structure
5. Long-span steel bridge members
6. Ship, machinery manufacturing frame structure
7. Train, car, tractor beam support
8. Port conveyor, high-speed baffle bracket

H-beam is economical section steel, widely used in industry, construction, bridges, oil rigs, etc. It is predicted that the demand for H-beam in China in 2005 was about 2.5 million tons, and the demand in 2010 was 5 million tons. The annual production capacity of H-beam is 1.2 million tons, and the market demand is huge.

 

Features of H-beams

1.High structural strength

Compared with I-beam, the section modulus is large, and the metal can be saved by 10-15% when the load bearing conditions are the same.

2. Flexible and rich design style

With the same beam height, the steel structure can be 50% larger than the concrete structure, making the building layout more flexible.

3. Lightweight structure

Compared with the self-weight of the concrete structure, the self-weight of the structure is reduced, and the internal force of the structural design is reduced, which can reduce the requirements for the foundation treatment of the building structure, facilitate the construction, and reduce the cost.

4.High structural stability

Hot-rolled H-beam steel structure has a scientific and reasonable structure, good plasticity and flexibility, and high structural stability. It is suitable for building structures that can withstand large vibration and shock loads and has a strong resistance to natural disasters. Building structure in the earthquake zone. According to statistics, in the world's magnitude 7 or more devastating earthquake disasters, H Beams-based steel structures have suffered the least damage.

5. Increase the effective 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 form of the building, it can increase the effective use area by 4-6%.

6. Save labor and materials

Compared with welding H Beams, it can obviously save labor and materials, reduce the consumption of raw materials, energy and labor, low residual stress, good appearance and surface quality.

7.Easy machining

Easy to connect and install, easy to remove and reuse.

8. Environmental protection

The use of H Beams can effectively protect the environment, which is specifically manifested in three aspects: first, compared with concrete, dry construction can be used, which generates less noise and less dust; second, due to the reduction of its own weight, the amount of soil taken for foundation construction is small, and Small damage to land resources, in addition to reducing the amount of concrete, reducing the amount of rock excavation in the mountains, is conducive to the protection of the ecological environment; Third, after the service life of the building structure expires, the amount of solid waste generated after the structure is demolished is small, and the value of scrap steel resources is high.

9. The high degree of industrial production

Hot-rolled H-beam-based steel structures have a high degree of industrial production, which is convenient for machine manufacturing, intensive production, high accuracy, easy installation, and easy quality assurance. It can be built into a real house manufacturing factory, bridge manufacturing factory, and industrial workshop manufacturing factory. The development of steel structures has created and driven the development of hundreds of emerging industries.

10. Fast construction speed

It has a small footprint and is suitable for all-weather construction, and is less affected by climatic conditions. The construction speed of a steel structure made of hot-rolled H Beams is about 2-3 times the construction speed of a concrete structure, the capital turnover rate is doubled, the financial cost is reduced, and the investment is saved. Taking China's "Tallest Building" Shanghai Pudong's "Jinmao Tower" as an example, the structural main body with a height of nearly 400m has completed the structural cap in less than half a year, while the steel-concrete structure requires a two-year construction period.
