Why Is Hot-rolled H-shaped Steel Selected As The Automobile Beam

            Hot-rolled H-shaped steel is an economic section steel with an optimized cross-section. Due to the use of the universal rolling method, compared with the I-beam produced by the pass method, it has great advantages in the control and adjustment of product size accuracy. Compared with welded H-shaped steel, hot-rolled H-shaped steel has a uniform cross-section performance, accurate cross-section dimensions, high precision, and lower manufacturing costs. When used in automobiles to replace the original I-beam for manufacturing the girder, it has the advantages of convenient construction, high stiffness, good bending resistance, smooth surface, high work efficiency, and low cost.

                    Adopting hot-rolled H-shaped steel as the girder of a trailer is a development trend. From the perspective of the trailer girder production process, using hot-rolled H-shaped steel conforms to the national industrial policies of energy conservation, environmental protection, and resource conservation. From the perspective of vehicle safety and reliability, the rolled H-shaped steel has a uniform overall cross-section performance, low residual stress, and no welding defects. When used to make the girder, the safety and reliability of the vehicle are more guaranteed. From the perspective of industry management, the rolled H-shaped steel has certain specification dimensions, reducing the randomness of the steel plate dimensions during the welding of the girder, making it impossible for production enterprises to arbitrarily change the girder dimensions to meet the unreasonable requirements of users, which is conducive to the national management of the modified vehicle industry and creates conditions for the governance of overloading. From the perspective of production costs, using rolled H-shaped steel as the girder has a lower comprehensive cost than welded girders, and using rolled H-shaped steel shortens the production cycle, advances the vehicle delivery time, and thus improves the production efficiency and competitiveness of automobile manufacturing enterprises.

                  GNEE Group is the first domestic enterprise with advanced technology for hot-rolled H-shaped steel. Based on the absorption and digestion of imported technologies, GNEE Group has achieved secondary technological innovation. It has successively developed a large number of high-performance special H-shaped steels, such as weather-resistant H-shaped steel for railway vehicles, fire-resistant H-shaped steel for construction, high-toughness H-shaped steel for oil platforms, and high-strength H-shaped steel for building foundation piles. The products have achieved serialization of steel grades and specifications. Domestic hot-rolled H-shaped steel has been widely used in various departments and industries of the national economy, and the product quality has been recognized by users. 

             All of our products are supplied in accordance with the standards of ASTM/AISI in the United States, DIN in Germany, JIS in Japan, and GB in China. We can also supply products according to the technical requirements provided by customers.

For H-beams, we have many specifications for you to choose from.
