Yongcheng Xingye Company is a professional manufacturer of building materials, which includes steel structure members, profiled metal sheet system, steel beam, metal roof & wall sandwich panel system, assembly prefabricate house, light steel structure villa and so on.
Considering the specific needs of the project, steel beam is chosen comprehensively. The selection factors include usage scenarios, material strength and durability, processing and welding performance, environmental factors, cost, as well as national and industry standards.
Ordinary carbon structural steel Q235 (in Chinese standard) is a commonly used material for steel beam. The Q235 is equivalent to A36 (in American standard). The beams can be used for load bearing in frame structures of architecture.
Low-alloy high-strength steel Q345 (in Chinese standard) is another important material for the steel beam. Q345 is equivalent to A572 Gr.50( in American standard) . The addition of alloy elements significantly improves its strength while maintaining good toughness. The material is suitable for building structures with high load-bearing capacity such as large bridges and high-rise buildings. The beam is widely used in the engineering field and can withstand large loads to ensure the safety and stability of the project.
H-shaped steel is mainly used for steel beam in steel structures. The beam is widely used in industries, construction, bridges, and other fields. Hot rolled H-beams are divided into three types: wide flange H-beams (HW), medium flange H-beams (HM), and narrow flange H-beams (HN).
HN is an H-beam with a height to flange width ratio greater than or equal to 2. It is mainly used for beams. The use of HN steel is equivalent to that of I-beams. This kind of H-beam is the H-type steel beam.
HM is an H-beam with a height to flange width ratio of approximately 1.33 to 1.75. It is mainly used in steel structures as steel frame columns. Also it is used as frame steel beams in frame structures that bear dynamic loads, such as equipment platforms.
HW is an H-beam with a height and flange width that is essentially equal. It is mainly used for columns in steel structures. The columns are mainly used as steel core columns in reinforced concrete frame structures, also known as stiff steel columns.
