Corrugated metal pipe (CMP) is commonly used in construction for various applications, particularly in drainage, stormwater management, and culvert systems.

Here’s an overview of corrugated metal pipe:


Corrugated metal pipe is typically made from galvanized steel, aluminum, or stainless steel. The metal sheets are formed into a corrugated shape, providing strength and flexibility.


Galvanized Steel

Galvanized steel corrugated pipe is the most common type. They are coated with a layer of zinc to enhance corrosion resistance, making them suitable for underground applications.


Aluminum corrugated pipe is lightweight and resistant to corrosion, making them ideal for applications where weight is a concern or in areas with aggressive soil conditions.

Stainless Steel

Stainless steel corrugated pipe offers superior corrosion resistance and durability, making them suitable for harsh environments or corrosive fluids.


Strength and Durability: Corrugated metal pipe is strong and durable, capable of withstanding heavy loads, ground pressures, and external forces.

Corrosion Resistance: Galvanized steel and stainless steel corrugated pipe is resistant to corrosion, extending their service life in aggressive soil conditions or exposure to corrosive substances.

Flexibility: Corrugated metal pipe can flex and accommodate minor ground movements without compromising their structural integrity, reducing the risk of cracking or failure.

Easy Installation: Corrugated metal pipe is lightweight and easy to handle, transport, and install compared to concrete or clay pipe. They require minimal machinery and labor for installation.


Drainage Systems: Corrugated metal pipe is used for stormwater management, agricultural drainage, and roadside drainage systems.

Culverts: Corrugated metal pipe is commonly used as culverts to convey water under roads, railways, and embankments. They provide a cost-effective and durable solution for bridging small to medium-sized waterways.

Retention Systems: Corrugated metal pipe can be used in detention or retention systems to temporarily store stormwater runoff and control peak flow rates.


Corrugated metal pipe requires regular maintenance to ensure proper functioning and prevent issues such as sediment buildup, debris blockage, or corrosion. Maintenance activities may include inspection, cleaning, and repair or replacement of damaged sections.

Overall, corrugated metal pipe offers a reliable and cost-effective solution for various construction applications, providing strength, durability, and flexibility in drainage and culvert systems. Proper selection, installation, and maintenance are essential to ensure the long-term performance of corrugated metal pipe in construction projects.
