In the new infrastructure construction, Prefabricated Steel Bridge is increasingly valued by engineers and project managers for its excellent high safety performance, construction speed and long life. From the Prefab Bridge for Creek for walking across creeks to the Prefabricated Steel Bridges for heavy traffic, the precast steel bridges provide much better answers than the traditional cast-in-place concrete bridges. It has been demonstrated that the cost of the superstructure of precast steel bridges can be up to 25.8% cheaper than that of the precast concrete alternative, and the cost advantage throughout the life cycle is particularly remarkable.
Factory-Based Production
The key benefit of Prefabricated Steel Bridge is its factory-based production. All sections of the bridge are welded and assembled in a controlled factory environment, then shipped to the site for quick installation. With this Redi-Road Prefab Bridge construction technique of shifting a great deal of work off site, the worker’s exposure to hazardous elements is minimized, along with the time that they are needed to work in an unstable environment in extremes of weather or adjacent to traffic.
Rapid Installation
A large number of prefabricated steel bridges can be built within two days, and some small Prefab Bridge for Creek even can be built in one day. When compared to traditional ‘stick built’ bridges, the installation time for Prefabricated Steel Bridges decreases from several days to a few hours and the total project time can be 30% to 50% less when compared to traditional bridge construction method.
Materials and Structure Design of Bridge Steel Structure
ZZ Group (short for Zhanzhi Group) bridge steel structure is made of excellent steel.
Material of the prefabricated steel structure bridge are commonly Q235B (similar to St37.2, S235JR, ASTM A36) and Q345B (similar to St52.3, S355JR). This Series of Prefabricated Steel Bridges have been perfectly engineered to support pedestrians, bicycles, light vehicles, small cars and heavy trucks.
ZZ Group (short for Zhanzhi Group) Steel Bridges can last more than 50 years with suitable maintenance. We also supply hot dipping galvanizing after fabrication for severe environment, which can protect steel over 100 years. The design of the Prefabricated Steel Bridges is based on and tested to meet international standards including AASHTO LRFD Bridge Design Specifications to provide a safe and secure solution.
