H-shaped steel is an economical cross-section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter “h”. Since all parts of H-shaped steel are arranged at right angles, H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used.
The use of H-shaped steel 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; second, due to the reduced weight, less soil is taken for foundation construction, which brings about little damage to land resources. In addition, the amount of concrete and 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 dismantled, the amount of solid waste generated is small, and the recycling value of scrap steel resources is high.
The steel structure mainly made of hot-rolled H-shaped steel has a high degree of industrial production, is convenient for mechanical manufacturing, intensive production with high precision and good quality. It can be built into a real house manufacturing factory, bridge manufacturing factory, industrial plant manufacturing factory, etc. . The development of steel structures has created and promoted the development of hundreds of emerging industries.
The project construction speed is fast, the area is small, and it is suitable for all-weather construction and is less affected by climate conditions. The construction speed of steel structures made of hot-rolled H-shaped steel is about 2-3 times that of concrete structures. The capital turnover rate is doubled, which reduces financial costs and thus saves investment. Taking the “Jinmao Tower” in Pudong, Shanghai, the structural main body with a height of nearly 400 meters was completed in less than half a year, while the steel-concrete structure required a two-year construction period.
In the process of processing structural steel, an important reason for choosing laser cutting equipment is its inevitable position in the future update of the steel structure plant. With the rapid development of the construction industry and the advantages of steel structures, the demand for this type of buildings is increasing. H-shaped steel is a commonly used structural material in steel structure plants. Its high strength and lightweight characteristics make it widely used in the construction field. H-shaped steel cutting factories need faster and more accurate laser cutting machines during the production process to meet market demand. It is in this context that laser cutting equipment has become indispensable equipment. Its high precision, high efficiency and flexibility can better meet the requirements of steel structure plants for product quality and production efficiency.
