This corrugated galvanized steel pipe is a buried steel culvert made from corrugated plate or pipe sections. The zinc layer protects the steel surface, while the corrugation helps the pipe carry soil and traffic load through flexible structure action.
It is often selected for road construction because the sections are lighter than concrete and can be assembled with bolts. The site still needs good bedding, layer-by-layer backfill, and bolt checks. If the water is salty or industrial wastewater may pass through, extra coating should be discussed before production.

Product Advantages
The corrugated galvanized steel pipe is easy to move and fit on sites where cranes have limited space.
1. Galvanized surface gives basic corrosion protection.
2. Corrugated body works with surrounding soil after backfill.
3. Bolted sections can be adjusted more easily than cast-in-place culverts.
Main Applications
A corrugated galvanized steel pipe is used for drainage and culvert projects with buried load.
1. Highway drainage under embankments.
2. Farm road and rural road culverts.
3. Industrial park stormwater channels.
4. Temporary construction access drainage.
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 used in saline soil?
A: A corrugated galvanized steel pipe can be used after soil and water corrosion are checked, and extra coating may be needed.
Q: Is the pipe delivered as one piece?
A: Small sizes can be supplied in sections; large sizes are often delivered as plates.
Q: What affects pipe thickness?
A: Cover depth, traffic load, diameter, soil type, and design code affect thickness.
