Corrugated steel pipe

Corrugated Metal Pipe (CMP) includes both:

Corrugated Steel Pipe (CSP)

Corrugated Aluminum Pipe (CAP)

CMP is pipe/conduit made from steel or aluminum which is corrugated to give it strength.

CMP is strong enough to handle, AASHTO Highway loading, Rail Road loading, and mining loading.

AASHTO considers Corrugated Metal Pipe (CMP) a metal/soil interactive structure. The overall performance depends on a quality backfill and installation.

A quality backfill is made up of a clean, well draining aggregate or sand material.

Corrugated steel pipe

Corrugated steel pipes (CSP) are a highly versatile and durable solution for a wide range of applications, particularly in drainage and stormwater management. These pipes are known for their strength, longevity, and ability to withstand various environmental conditions. CSPs are available in multiple coatings and configurations to suit specific project needs.


Common coatings include galvanized, aluminized, and polymer coatings. Galvanized CSPs, coated with zinc, can last up to 50 years, making them a cost-effective choice for many projects. Aluminized CSPs, coated with aluminum, offer a longer service life of up to 75 years and are ideal for environments with moderate corrosive conditions. Polymer-coated CSPs provide the highest level of protection, with a service life of up to 100 years, suitable for the most challenging environments due to their superior corrosion and abrasion resistance.


CSPs are widely used for culverts, storm sewers, and small bridge replacements due to their lightweight, ease of installation, and the ability to be custom-fabricated to meet specific project requirements. Their design flexibility allows for various shapes and sizes, accommodating different site conditions and structural needs.


In summary, corrugated steel pipes offer a reliable and cost-effective solution for numerous infrastructure projects, with customizable options to ensure optimal performance and longevity in diverse environmental conditions. For more detailed information, you can visit corrugatedmetalculvert.
