High Efficiency Prefabricated Long-span Steel Structure Bridge Building

Made in China with high efficiency prefabricated long-span steel structure bridge building

Product Description:

The steel structure bridge uses high-strength steel as the core load-bearing component, and through the structural forms of box girders, trusses, arch ribs, etc., it crosses rivers, lakes and seas and complex landforms, and achieves a span breakthrough of tens of meters to kilometers. With the characteristics of high tensile strength and good toughness, steel shows the advantages of light weight and high efficiency in long-span bridges, and its components can be prefabricated in the factory and transported to the site for assembly, with a short construction period and controllable precision, which can greatly reduce the impact of on-site operations on traffic and the environment. The surface is supported by anti-corrosion coating, fire protection treatment and intelligent monitoring system to improve the durability and safety of the structure, and the modular design is convenient for later maintenance and expansion, so that the steel structure bridge has become a functional and iconic hub node in the transportation network with strong spanning ability and modern aesthetic form.

Product Advantages:

With the excellent mechanical properties of high-strength steel, steel structure bridges can easily achieve super-large spans. Through the suspension cable, cable-stayed and other structural forms, the main span can reach more than a kilometer, such as the suspension bridge uses the strong tensile ability of the main cable to cross the wide sea area and canyon, without the need to set up a large number of piers in the water, reduce the impact on the waterway and ecology, provide sufficient space for shipping, flood discharge, etc., and perfectly solve the problem of transportation connection in the complex geographical environment.

The steel structure bridge adopts the mode of factory prefabrication and on-site assembly, which significantly improves efficiency. Steel beams, steel boxes and other components are accurately formed in the factory through CNC machining and automatic welding, and the error is controlled at the millimeter level, and the hoisting equipment is used to quickly splice after transportation to the site, and the construction period is shortened by about 40% compared with concrete bridges. At the same time, this kind of dry construction greatly reduces on-site wet operations, reduces noise and dust pollution, and is less disturbed by weather factors, ensuring the stability of the project progress, especially suitable for key projects in dense urban areas or tight construction periods.

The steel structure bridge adopts a modular design, which is convenient for later functional upgrading and structural transformation. As traffic flows grow or demand changes, lanes, sidewalks or pipelines can be flexibly added; After the end of the bridge's service life, the steel can be 100% recycled and reused, reducing construction waste and resource waste, in line with the concept of green development. Its simple and fluid shape and modern material characteristics can also be integrated with the surrounding environment to create a landmark building with both practical function and landscape value.

​Our advantages

High-quality material supply: Establish long-term and stable cooperative relations with well-known steel suppliers, and strictly control the quality of materials. From the source, ensure that the strength, toughness and other properties of the main materials such as hot-rolled section steel, cold-formed thin-walled section steel and steel plate meet high standards, and provide a solid guarantee for the construction quality. At the same time, auxiliary materials such as fire prevention and anti-corrosion are also strictly screened to ensure the durability of the building.

Efficient construction capability: mature factory prefabrication and on-site installation process. The factory has advanced production equipment, which can realize high-precision processing of steel structural components and ensure the stable quality of prefabricated components. The on-site construction team is skilled, using advanced installation technology and equipment, with efficient project management, and strictly following the construction plan, greatly shortening the construction period and reducing the project cost.

Comprehensive service system: provide one-stop service from pre-project consultation, scheme design, construction to post-maintenance. In the early stage of the project, provide customers with professional technical consultation and feasibility analysis; During the construction process, communicate with customers in a timely manner to solve problems; After the project is delivered, a sound after-sales service system will be established, regular return visits will be provided, and maintenance guidance will be provided to ensure the long-term stable operation of the building.
