GWD-Type Long-span Prefabricated Steel Truss Bridge

In the grand picture of bridge construction, Evercross Bridge, with its outstanding innovative spirit and exquisite engineering technology, has brought to the industry the remarkable masterpiece, the GWD-Type Long-span Prefabricated Steel Truss Bridge.

The story of the GWD-Type Bridge began in Germany. Its advanced design concept and unique structural advantages attracted the high attention of the engineers from Evercross Bridge. After an in-depth and detailed structural analysis, Evercross Bridge decisively introduced this technology and started mass production in China. Behind this decision is a deep insight into the technical barriers and shortcomings of the traditional Bailey Bridge.

The Bailey Bridge, as a common prefabricated steel bridge structure, occupies an important position in the field of bridge construction due to its simple structure, strong adaptability, and good interchangeability. However, even under a small load, the single-span length of the Bailey Bridge can only reach 60 meters, which undoubtedly becomes a limitation in some projects that require a higher span.

In contrast, the GWD-Type Bridge launched by Evercross shows great advantages. Although it uses larger section steel for the truss, the structure is simpler. It not only inherits the strong adaptability of the prefabricated Bailey steel bridge but also successfully makes up for its deficiency in span. By increasing the single-span length, the GWD-Type Bridge not only saves the cost of piers for large-scale projects but also provides strong support for the smooth flow of traffic and economic development.

The 100-Type Bailey Bridge studied during World War II and the later HD200-Type Bailey Bridge improved and designed by Mabey Company have been constantly evolving. However, compared with the D-Type Bridge introduced from Germany, which is known for its strength and suitable for longer spans, Evercross Bridge's GWD-Type Bridge has more advantages. Especially in the construction of long-span bridges, Evercross bridge clearly pointed out that the use of Bailey Bridges is not recommended, and the GWD-Type Bridge is more recommended.

The truss panels of the Bailey Bridge are connected by Bailey pins, with a pin hole diameter of 50MM and a Bailey pin diameter of 49.5MM. The more Bailey pins used for connection, the more gaps there will be, and the greater the deflection of the bridge will be. The GWD-Type Bridge uses high-strength bolts for connection, with smaller gaps and less deflection, ensuring the stability and safety of the bridge.

The GWD-Type long-span prefabricated steel bridge has several model aliases, such as the CD450-Type, CD-Type, 450-Type, and HBD60-Type. Its standard single-lane bridge deck has a net width of 4.2M, and the maximum span can reach 82.296 meters; the standard double-lane bridge deck has a net width of 7.35M, and the maximum span is 91.44 meters. The length of the truss panel is 3048MM × 2350MM. Such design parameters enable the GWD-Type Bridge to meet the needs of different projects.

In today's era of rapid development, Evercross bridge's GWD-Type Bridge, with its excellent performance, advanced technology, and reliable quality, has become the first choice for bridge construction. Whether it is crossing mountains, rivers, or connecting cities and villages, the GWD-Type Bridge will play an irreplaceable role in building a solid bridge for people's lives and economic development.

Choosing Evercross bridge's GWD-Type Bridge means choosing innovation, quality, and the future. Let us look forward to the GWD-Type Bridge shining in more projects and writing a more brilliant chapter for the world's bridge construction.
