As a new type of transportation facility, metal culverts play an increasingly important role in modern transportation construction due to their high efficiency, environmental protection, and durability. In the future, with the continuous progress of technology and the expansion of application fields, metal culverts will make greater contributions to the transportation construction industry.

The construction cost of metal culverts is relatively low, especially in areas lacking sand and gravel materials or with low foundation bearing capacity, and their advantages are more significant. Metal culverts are not only widely used in the construction of transportation infrastructure such as highways and railways, but also in the reinforcement, emergency rescue, and communication engineering of bridges. Metal culverts are constructed using assembly methods, which can significantly shorten the construction period compared to traditional reinforced concrete culverts.
