H-beam is a kind of high efficient profile with economic cross-section which is more optimized in cross-section area distribution and more reasonable in strength-to-weight ratio, and is named because its cross-section is the same as the letter "H" in English. Since all parts of H shaped steel are arranged at right angles, H section steel has the advantages of strong bending resistance, simple construction, cost saving and light weight structure in all directions, and has been widely used. As a subdivided variety of metal H beam application, heavy H section beam is the future development direction of steel structure field.

Heavy H-beam is widely used in various civil and industrial building structures, various large-span industrial plants and modern high-rise buildings, especially in areas with frequent seismic activities and industrial plants under high-temperature working conditions. As well as the requirements of large bearing capacity, good section stability, large span of large steel structure bridge, heavy machinery manufacturing equipment, engineering pit support and water conservancy dam project.

The EN standard for European Standard H shaped beam is the standard and type of H beam iron for construction specified in the European Standard (EN). These standards and types are widely used in the construction field in Europe and around the world and are considered to be an efficient and environmentally friendly construction solution.

The EN standard for European standard H metal beam is divided into three classes: light (Light), medium (Medium) and heavy (Heavy). Each type of H shape steel beam is available in different cross-section sizes and weights to meet different construction needs.

EN Standard metal beam structure are available in three main quality grades S235, S275 and S355. For example, S235 material and S275 material represent carbon structural steel and S355 is low alloy steel. British standard H column steel is a cross-section area distribution is more optimized, the strength-to-weight ratio is more reasonable economic cross-section of high-efficiency profiles, because of its cross-section and the English letter "H" and the same name.

S235 (JR, J0, J2, k2) is a European standard carbon structural steel plate, the implementation of the EN10025 standard. S235 (JR, J0, J2, k2) steel plate carbon structural steel carbon content of less than 0.8%, carbon structural steel containing manganese is divided into normal manganese content (containing manganese 0.25% -0.8%) and higher manganese content (containing manganese 0.7%-1.2%) two groups, the latter has a better The latter has better mechanical properties and processing performance.

H steel profile steel is optimized by the development of I-beam steel section mechanical properties of a more excellent economic section of steel, especially section and the English letter "H" the same name. Its characteristics are as follows:

◆ Wide flange, large lateral stiffness. Strong bending resistance, about 5%-10% than I-beam.

◆The two surfaces of flange are parallel to each other, which makes connection, processing and installation easy.

◆ Compared with welded I-beam, it has low cost, high precision, low residual stress, no need of expensive welding materials and weld testing, saving about 30% of steel structure production cost.

◆ Under the same sectional load. The weight of hot rolled H-steel structure is 15-20% less than that of traditional steel structure.

◆ Compared with concrete structure, hot rolled H-steel structure can increase the use area by 6%, while the structural self-weight is reduced by 20% to 30%, which reduces the internal force of structural design.

◆ Steel H profile can be processed into T-beam, and honeycomb beam can be combined to form various cross-section forms, which greatly meets the needs of engineering design and production.

◆ High structural strength: Compared with I-beam, the section modulus is large, which can save 10-15% of metal when the bearing conditions are the same.

◆ Flexible and rich design style: in the case of the same beam height, the opening of steel structure can be 50% larger than that of concrete structure, which makes the building layout more flexible.

◆ High structural stability: the steel structure mainly made of hot rolled H-section steel beam steel has a scientific and reasonable structure, good plasticity and flexibility, high structural stability, suitable for building structures with large vibration and impact loads, and strong resistance to natural disasters, especially suitable for building structures in some multi-earthquake zones. According to statistics, in the devastating earthquake disaster of magnitude 7 or above in the world, the degree of victimization of h beam section-based steel structure buildings is minimized.

◆ Increase the effective use area of the structure: compared with concrete structure, the cross-section area of steel structure column is small, which can increase the effective use area of the building, depending on the different forms of the building, it can increase the effective use area by 4-6%.

◆ Convenient for mechanical processing: easy for structural connection and installation, also easy for dismantling and reuse.

◆ Environmental protection: the use of h steel profile can effectively protect the environment, specifically in three aspects: First, compared with concrete, can be used in dry construction, generating little noise, less dust; Second, due to the self-weight reduction, the foundation of the construction of the amount of soil is less, less damage to land resources, in addition to a large number of reduction in the amount of concrete to reduce the amount of excavation and stone excavation, is conducive to ecological protection; Third, the expiration of the service life of the building structure, structure Third, after the expiration of the service life of the building structure, the amount of solid waste generated is small, and the recycling value of scrap steel resources is high.

◆ Fast construction speed: covers an area of small, and is suitable for all-weather construction, less affected by weather conditions. The construction speed of steel structure made of hot rolled steel H beam is about 2-3 times of the construction speed of concrete structure, which doubles the capital turnover rate and reduces the financial cost, thus saving investment.
