Large Span Prefabricated Truss Bridge Construction Portable Steel Bridges

Large Span Prefabricated Truss Bridge Construction Portable Steel Bridges

The steel bridge, like a dragon made of steel, spans between rivers, lakes and seas or valleys. It is mainly constructed of steel, and the steel girders are straight and slender, as tight and powerful as the strings, supporting the backbone of the entire bridge. The steel frame of the bridge is simple and rhythmic, and the staggered members support each other, forming a stable mechanical system, highlighting the beauty of rationality and order. Under the sun, the surface of the steel shines with a metallic luster, cold and resolute. Its construction technology is exquisite, and every welding point is tightly fitted, ensuring the strength and stability of the bridge in various complex environments.

Product Advantages:

High strength-to-weight ratio
Steel has a high strength and is able to withstand large loads, while its weight is relatively light. This enables steel structure bridges to be realized with relatively small structural size and weight when spanning larger spans, reducing the pressure on the foundation, and is especially suitable for building large-span bridges, such as suspension bridges, cable-stayed bridges, etc.

The construction speed is fast
The components of the steel structure bridge can be prefabricated in the factory and then transported to the construction site for assembly. This prefabricated construction mode greatly reduces the time and workload of on-site construction, improves the construction efficiency, and can quickly realize the opening of the bridge, which is of great significance for shortening the construction period of the project and reducing the impact on traffic and the surrounding environment.

Good seismic performance
Steel has good toughness and ductility, under the action of external forces such as earthquakes, steel structure bridges can absorb and dissipate energy through their own deformation, and are not prone to sudden brittle failure. Therefore, steel structure bridges have obvious advantages in areas with high seismic fortification requirements, and can better ensure the structural safety and use function of bridges in the event of earthquakes.

High durability
After proper anti-corrosion treatment, the steel can maintain good properties for a long time. For example, the use of hot-dip galvanizing, spraying anti-corrosion coatings and other measures can effectively prevent steel rust and corrosion and prolong the service life of bridges.

Why Choose Us

Professional team: We have a professional design team composed of senior structural engineers, architectural designers, etc. They have solid professional knowledge and rich practical experience, and can deeply understand the diverse needs of customers, whether it is a conventional industrial plant or a unique commercial building, they can accurately grasp the key points of design. In the early stages of the design process, the team will fully communicate with the client to understand the functional positioning, spatial layout requirements, budget constraints and expected service life of the project in detail, so as to lay a solid foundation for the subsequent design work.

Process quality control: In the process of steel structure processing and production, multiple quality control points are set up. For example, real-time monitoring of key processes such as cutting, drilling, and welding of steel is carried out, and operations are carried out in strict accordance with process standards. Non-destructive testing technology, such as ultrasonic flaw detection, magnetic particle flaw detection, etc., is used to inspect the quality of welded joints to ensure that the welding quality meets the requirements of the design grade. Each completed process, the quality inspection is carried out, and only after passing can the next process be entered to avoid the flow of unqualified products into the next link.

Transportation plan planning: according to the size, weight, quantity of the steel structure, the geographical location of the project site, traffic conditions and other factors, formulate a reasonable transportation plan. Choose the right transport vehicles, such as flatbed trucks, low-bed semi-trailers, etc., to ensure that the goods can be loaded and transported safely and stably.

Choosing our steel structure storage products is to choose professionalism, quality, efficiency and value. We look forward to working with you to create exceptional construction projects.
