corrugated metal arch pipe used when a project needs a wide opening but does not want a full round pipe shape. The arch form gives more usable waterway or passage height while still using corrugated steel plate sections.
It is common in road culverts, drainage crossings, and small underpass structures. The side foundation and backfill quality matter a lot, because the arch shape transfers load to the sides. Before production, the drawing should confirm span, rise, plate thickness, bolt layout, and end treatment.

Product Advantages
The corrugated metal arch pipe can keep a larger clear opening under shallow cover.
1. Arch form works well where round pipe height is not suitable.
2. Bolted plates are easier to deliver to remote sites.
3. End shape can be adjusted for slope and water flow.
Main Applications
A corrugated metal arch pipe is useful where a low profile and wider opening are needed.
1. Road crossing culverts with limited cover height.
2. Agricultural drainage and waterway passages.
3. Small vehicle or animal passage openings.
4. Rebuild projects where concrete work is hard to arrange.
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: Is the backfill important?
A: Yes. A corrugated metal arch pipe needs controlled side backfill because the arch sends load to both sides.
Q: Can it be used for traffic passage?
A: Yes, if span, rise, load, and foundation are designed for that use.
Q: Can the end be beveled?
A: Yes. End treatment can follow slope, headwall, or project drawing.
