Building long-span steel structure shell truss structure bridge building materials
The construction technology of steel structure bridges is changing with each passing day, from the traditional on-site riveting and welding, to today's prefabricated assembly construction, such as jacking method, cantilever construction method, etc., which greatly improves the construction efficiency, shortens the construction period, and reduces the impact on the environment. At the same time, the application of non-destructive testing, intelligent monitoring and other technologies allows the health status of the bridge to be grasped in real time, providing a strong guarantee for its safe operation. Looking forward to the future, steel structure bridge technology will continue to innovate in a more efficient, intelligent and green direction, continue to break through engineering problems, and create more architectural miracles.

Product Description:
Steel structure bridges take steel as the core component, and occupy an important position in modern bridge construction by virtue of the excellent characteristics of steel. The main steel types are diverse, and the I-beam and H-beam in the hot-rolled section steel are often used to construct bridge components that bear large bending moments, such as key parts such as girders, because of their good bending resistance; Channels and angles play an indispensable role in supporting and connecting components due to their unique structural form. Steel plate, as a highly malleable basic material, through cutting, welding and other fine processes, turned into a box girder, plate girder and other complex shape of components, according to the force demand of different parts of the bridge, the selection of appropriate thickness of the steel plate, thick plate is used to withstand strong pressure and tensile force, thin plate is used in the area with relatively low strength requirements. Steel pipes have significant advantages in specific structural bridges, such as concrete-filled steel tube arch bridges, where steel pipes work in tandem with the concrete filled inside, which greatly improves the compressive and torsional performance of the components and enhances the overall stability of the bridge.
In order to meet the needs of different environments and projects, special performance steels came into being. High-strength steels, such as Q420 and Q500, rely on their yield strength and tensile strength that far exceed those of ordinary steels, which not only reduce the weight of the bridge, but also ensure that the structure has sufficient bearing capacity, so that the bridge can span a wider space and achieve the construction of a larger span. Weathering steel is to incorporate a small amount of copper, phosphorus, chromium, nickel and other alloying elements into ordinary steel, which can form a dense and self-protective rust layer on the surface of the steel in harsh environments such as coastal, humid or serious industrial pollution, which can effectively resist corrosion, reduce the use and maintenance cost of anti-corrosion coating, and prolong the service life of the bridge.
In the connection link, welding materials and bolting materials play a key role. When welding, welding rods, welding wires and fluxes need to be accurately matched with different types of steel to ensure that the welded joints have the same strength, toughness and corrosion resistance as the base metal. High-strength bolts, usually made of alloy structural steel such as 40Cr and 35CrMo, have high strength and good fatigue resistance after heat treatment, with nuts and washers with high precision and strength adaptation, and are widely used in bridges that are easy to install and disassemble, such as steel truss joints, bridge deck and beam connection points, etc., to ensure that the connection is stable and reliable.
