What are the main forms of steel structures in bridges?

Steel girders: Steel girders are spatial structures composed of multiple members connected by nodes. They have advantages such as light weight, high load-bearing capacity, and strong spanning ability. In bridge engineering, steel girders are often used in the construction of large-span bridges, such as railway bridges and highway bridges.

Heavy factory steel structure

Heavy industrial steel structures refer to factory building structures that use steel as their main components. This type of structure has multiple advantages. First, it has a strong load-bearing capacity, capable of withstanding large spans and heavy loads to meet the requirements of industrial production equipment. Second, it has high stability. Through reasonable design and reinforcement, it can effectively resist external forces such as earthquakes and wind, ensuring building safety. In addition, heavy industrial steel structures are easy to construct and have short construction periods, which can improve construction efficiency and reduce engineering costs.

Light steel structure building

Light steel structure buildings are a new type of building system that uses light steel materials (such as cold-formed thin-walled steel) as the main components, assembled into a building structure through certain connectors and support systems. Using lightweight steel as the main material, it is lightweight and high-strength, with advantages such as good earthquake resistance, fast construction speed, and efficient use of building area. Therefore, it is widely used in villas, light industrial plants, warehouses, and other building fields.

Preparatory work before steel structure installation and welding

Welding materials: Ensure that the welding materials and equipment used meet the standards and have excellent performance. For example, welding rods should be dried in a high-temperature drying oven, and the number of drying times should not exceed two; the welding wire packaging should be intact. If damage leads to contamination, bending, or disorder of the welding wire, part of it should be discarded; the purity of CO2 gas should not be less than 99.9% (volume ratio), and the water content should be less than 0.05% (weight ratio). Stop using the bottle when the high pressure inside is lower than 1 MPa.
