Steel Bridge Structure
The basic components of a bridge include the upper structure, lower structure, support system, and ancillary facilities. The substructure refers to the part of a bridge located below the support, also known as the supporting structure, which includes piers, abutments, and the foundation of piers. The adjacent two span bridge is located in the middle of the bridge, and the basic concept of the box girder structure is that all upper structures become integral hollow beams. When the main load passes through any position on the bridge, all parts of the hollow beam (ribs, top plate, and bottom plate) participate in the force as a whole. The lower structure is usually made of steel plates, steel pipes, angle steels, H-beams, and other parts, which are welded together through components and ultimately connected on-site by welding or bolts. Xinyue can provide customers with design analysis, drawing splitting, steel production, welding and forming work, etc.

High strength, light weight
Steel bridge superstructures are generally lighter than other bridge superstructures of different material composition which typically result in smaller and less costly foundations and suitable for large-span and complex terrain. Lighter superstructures also reduce seismic forces by significant amounts which can be a major advantage in regions with high seismic activities.
Shorter Construction Period
The factory has a high degree of prefabrication and a short construction period, making it suitable for Rapid construction time .
Due to their modular design, steel bridge structures can be built quicker than employing conventional construction methods. In most instances, steel components and other smaller elements are fabricated off-site, simultaneously with other work scopes and then transported to the job site. Assembled in modules or sections of calculated weight, launching and installation of the bridge parts such as beams and girders can be done with ease, in matter of hours.
Green environmental protection and sustainability .
Steel can be 100% recycled and reused. When buildings are demolished, the material loss rate is less than 5%, which is much lower than the over 30% of concrete. In addition, there is less dust and noise pollution during the construction process, which meets the modern engineering requirements for low-carbon and environmental protection.

Steel prefabricated components refer to assembly parts that are produced and processed to a certain extent in the factory, with an independent structural system, and can be directly transported to the construction site for installation. Common steel structure prefabricated components include steel beams, steel columns, steel bridge beams, steel structure floor slabs, etc. According to their application and form, they can be divided into frame prefabricated parts, plate prefabricated parts, steel pipe prefabricated parts, etc. The advantages of this structure include high strength, light weight, good overall stiffness, and strong resistance to deformation. It is particularly suitable for constructing large-span, ultra-high, and ultra-heavy buildings. After prefabrication in the factory, it can greatly save installation and welding work on the project site. Steel prefabricated components can be used for various types of mountain bridges, railway bridges, highway bridges, urban light rail bridges, substations, substations, ship structures, elevators, offshore platform structures, etc
Offshore structures are built specifically for drilling oil and gas deposits deep under the sea bed. Whilst applications will vary, all will have exposure to the effects of salt water corrosion, powerful sea currents often dictated by the tides and strong winds. Our search for natural fuel resources has stretched into even more inaccessible areas such as the Arctic which has also resulted in rigs drilling at much greater depths and hence lower temperatures. Structures in harsh working environments like these require a specific range of steels to promote greater safety, longer working life and reduce the risk of failure which in certain cases could prove disastrous.
