H-beam manufacturers: At present, there are mainly Masteel, Laigang, Rizhao Steel, Jinxi Steel and Changzhi Steel in China. Masteel is the first enterprise in China to produce H-beam.
Maanshan Maanshan Masteel H-beam Factory, Anhui Province:
The main equipment is imported from Denmark, Siemens, Etam and other companies in the United States. The production line takes continuous casting beam blank as raw material, adopts walking beam heating furnace, and adopts the technological processes of double-roll long-stroke cogging machine, universal roughing mill and universal finishing mill.
The universal mill is equipped with AGC roll gap automatic control system and quick roll changing device, and the hot saw is accurately positioned by computer. Keywords hydraulic stepping cooling bed, nine-roll cantilever straightener with adjustable roll spacing,
The production management of the whole plant adopts computer three-level control. The process equipment and automation degree of this factory can be called the world-class H-beam factory of Laigang. The main equipment was imported from Nippon Steel and Toshiba Corporation of Japan, with a designed annual production capacity of 500,000 tons, and now it has reached an annual production capacity of 800,000 tons. Its process equipment, process flow and product specifications are almost the same as the H production line of Italy's Dagnelie imported from Rizhao.

The company has a professional fleet to provide customers with one-stop services such as inspection, ordering, delivery, invoicing and settlement. Holidays are endless, and the company adheres to the business philosophy of "customer first, survival by quality and development by reputation" to meet customer needs.
H-beam characteristics:
1. The structural strength is high. Compared with I-beam, the section modulus is larger. Under the same bearing conditions, metal 10- 15% can be saved.
2. Flexible and rich design style? With the same beam height, the width of steel structure can be 50% larger than that of concrete structure? , thus making the architectural layout more flexible.
3. Is the structure light? Compared with the self-weight of concrete structure, the self-weight of structure is lighter, which reduces the internal force of structural design, and can make the foundation treatment requirements of building structure lower, the construction easier and the cost lower.
4. High structural stability? The steel structure with hot-rolled H-beam is scientific and reasonable in structure, good in plasticity and flexibility, high in structural stability and strong in natural disaster resistance, especially for some building structures in earthquake-prone areas. According to statistics, among the devastating earthquake disasters above magnitude 7 in the world, the damage of H-beam steel structures is the least.
5. Increase the effective use area of the structure? Compared with concrete structure, the cross-sectional area of steel structure column is smaller, which can increase the effective use area of the building, and according to different forms of the building, it can increase the effective use area by 4-6%.
6. Compared with welding H-beam, it can obviously save labor and materials, reduce the consumption of raw materials, energy and labor, and has low residual stress and good appearance and surface quality.
7. Convenient processing, structural connection and installation, easy disassembly and reuse.
8. The use of environmental protection H-beam can effectively protect the environment, which is manifested in three aspects: First, compared with concrete, dry construction can be used, with less noise and dust; Second, due to the reduction of self-weight, the amount of soil taken for foundation construction is small, and the damage to land resources is small. In addition, the consumption of concrete is greatly reduced, which is beneficial to protect the ecological environment; Third, the service life of the building structure expires, and after the structure is demolished, the amount of solid waste generated is small and the recycling value of scrap steel resources is high.
9. High degree of industrial production The steel structure mainly made of hot-rolled H-beam has high degree of industrial production, which is convenient for mechanized manufacturing, intensive production, high precision, convenient installation and easy quality assurance, and can be built into real house manufacturing plants, bridge manufacturing plants and industrial workshop manufacturing plants. The development of steel structure has created and promoted the development of hundreds of emerging industries.
I must have read the introductions of H-beam manufacturers listed in Bian Xiao, and I have got a certain understanding of these H-beam manufacturers. You can analyze and judge step by step according to the above content, and find out the manufacturers that are suitable for you and can meet your own needs to cooperate. H-beam has many advantages, such as strong bending resistance and wide application; The self-weight is light, and the construction is more convenient; The design style is changeable and flexible.
