Metal culvert, also known as metal corrugated culvert or steel corrugated pipe culvert, is a circular corrugated pipe structure made of corrugated metal plates. It is made of thin steel plates that have been rolled after being compressed, and has high stiffness and compressive strength. The design of metal culverts is simple, with a short production cycle and convenient installation, making them suitable for transportation construction under various environmental conditions.

The metal culvert adopts standardized design and production, with simple design and short production cycle. On site installation does not require the use of large equipment, making it easy to carry out construction under various environmental conditions. The use of metal culverts reduces the demand for conventional building materials such as cement, yellow sand, stones, and wood, which is beneficial for environmental protection. As a flexible structure, metal culverts have certain seismic resistance and can adapt to large settlement and deformation, especially suitable for areas with low bearing capacity of soft soil, expansive soil, collapsible loess and earthquake prone areas.
