corrugated metal culvert is a metal water passage installed under roads, railways, yards, or embankments. It guides water through the road base and helps protect the road surface from washout.
The structure depends on both steel and soil. After assembly, the backfill must be placed in layers so the pipe does not move or deform. For cold areas, soft ground, or heavy traffic, the plate thickness and coating should be confirmed with the drawing, not guessed from a simple size table.

Product Advantages
The corrugated metal culvert can reduce wet concrete work and shorten road closure time.
1. It can be delivered as plates for easier transport.
2. Fast bolting helps speed up culvert replacement.
3. Shape can be selected by waterway and cover height.
Main Applications
A corrugated metal culvert is used when drainage needs a fast-installed buried structure.
1. Bridge and culvert replacement work.
2. Stormwater drainage under roads.
3. Mine, park, and industrial access roads.
4. Water passage projects in frozen or soft ground.
Our Services
Tengshida can discuss drawing size, wind load, surface finish, packing method, and loading plan before production. For site projects, the work can also include drawing review, material confirmation, factory inspection photos, and basic installation notes.
FAQ
Q: Can it be installed in rainy season?
A: A corrugated metal culvert can be installed in many seasons, but water control and backfill quality must be planned.
Q: Does shape affect water flow?
A: Yes. Round and arch forms have different flow areas and cover needs.
Q: What coating is better?
A: It depends on soil, water, and design life. Galvanizing can be combined with epoxy or asphalt coating.
