H-beam theoretical weight table What are the characteristics of H-beam
time2025/04/22
- H-beam is a new type of economical steel for construction.
Structural introduction
H-shaped steel is a new type of economical construction steel. The cross-sectional shape of H-shaped steel is economical and reasonable, with good mechanical properties. When rolling, the extension of each point on the cross section is relatively uniform and the internal stress is small. Compared with ordinary I-shaped steel, it has the advantages of large cross-sectional modulus, light weight, and metal saving, which can reduce the building structure by 30-40%; and because its legs are parallel inside and outside, and the leg ends are right angles, it can be assembled into components, which can save 25% of welding and riveting work. It is often used in large buildings (such as factories, high-rise buildings, etc.) that require large load-bearing capacity and good cross-sectional stability, as well as bridges, ships, lifting and transportation machinery, equipment foundations, brackets, foundation piles, etc.

Steel H Beam is an economical cross-sectional steel with better cross-sectional mechanical properties developed from the optimization of I-shaped steel, especially the cross-sectional shape is the same as the English letter "H". Its characteristics are as follows:
* Wide flange and large lateral stiffness.
*Strong bending resistance, about 5%-10% higher than I-beam.
·The parallel surfaces of the flanges make connection, processing and installation easy.
Compared with welded I-beams, it has low cost, high precision, low residual stress, no need for expensive welding materials and weld inspection, and saves about 30% of the cost of steel structure production.
*Under the same cross-sectional load, the weight of hot-rolled H-steel structure is 15%-20% lighter than that of traditional steel structure.
Compared with concrete structure, hot-rolled H-steel structure can increase the usable area by 6%, while the self-weight of the structure is reduced by 20% to 30%, reducing the internal force of the structural design.
*H-shaped steel can be processed into T-shaped steel, and honeycomb beams can be combined to form various cross-sectional forms, which greatly meets the needs of engineering design and production.
Application range
H-shaped steel is mainly used for beam and column components in industrial and civil structures.
Steel structure load-bearing brackets for industrial structures
Steel piles and supporting structures for underground projects
Structures of industrial equipment such as petrochemicals and electric power
·Long-span steel bridge components
·Ship and machinery manufacturing frame structures
·Train, automobile, tractor beam brackets
·Port conveyor belts, high-speed baffle brackets
H-shaped steel is an economical cross-section steel material, widely used in industry, construction, bridges, oil drilling platforms, etc. It is predicted that my country's demand for H-shaped steel will be about 2.5 million tons in 2005 and 5 million tons in 2010, but my country's annual production capacity of H-shaped steel is 1.2 million tons at present, and the market demand is very huge.
What are the characteristics of H-shaped steel?
1. High structural strength
Compared with I-shaped steel, it has a large section modulus and can save 10-15% of metal under the same load-bearing conditions.
2. Flexible and rich design styles
Under the same beam height, the span of the steel structure can be 50% larger than that of the concrete structure, making the building layout more flexible.
3. Light weight of the structure
Compared with the concrete structure, the reduction of the structure's own weight reduces the internal force of the structural design, which can make the foundation treatment requirements of the building structure low, the construction is simple, and the cost is reduced.
4. High structural stability
The steel structure mainly composed of hot-rolled H-shaped steel has a scientific and reasonable structure, good plasticity and flexibility, and high structural stability. It is suitable for building structures that withstand large vibration and impact loads, and has strong resistance to natural disasters. It is especially suitable for building structures in some earthquake-prone areas. According to statistics, in the world's devastating earthquake disasters of magnitude 7 or above, steel structure buildings mainly composed of H-shaped steel suffered the least damage.
5. Increase the effective use area of the structure
Compared with concrete structures, the cross-sectional area of steel structure columns is smaller, 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%.
6. Save labor and materials
Compared with welded H-shaped steel, it can significantly save labor and materials, reduce the consumption of raw materials, energy and labor, have low residual stress, and good appearance and surface quality.
7. Easy to machine
Easy to connect and install the structure, and easy to dismantle and reuse.
8. Environmental protection
The use of H-shaped steel can effectively protect the environment, which is specifically manifested in three aspects: First, compared with concrete, dry construction can be used, which produces less noise and less dust; second, due to the reduced deadweight, the amount of soil taken for foundation construction is small, and the damage to land resources is small. In addition, the amount of concrete is greatly reduced, and the amount of mountain excavation and stone 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 dismantled, the amount of solid waste generated is small, and the recycling value of scrap steel resources is high.
9. High degree of industrialization
The steel structure mainly based on hot-rolled H-shaped steel has a high degree of industrialization, which is convenient for mechanical manufacturing, intensive production, high precision, convenient installation, and easy quality assurance. It can be built into a real house manufacturing factory, bridge manufacturing factory, industrial plant manufacturing factory, etc. The development of steel structure has created and driven the development of hundreds of emerging industries.
10. Fast construction speed
It occupies a small area and is suitable for all-weather construction, and is less affected by climatic conditions. The construction speed of steel structure made of hot-rolled H-shaped steel is about 2-3 times that of concrete structure, and the capital turnover rate is doubled, which reduces financial expenses and saves investment.
