Galvanized corrugated steel pipe is the traditional choice for CMP. This corrugated steel pipe is manufactured from zinc coated steel sheets and offers a minimum 50 year service life.

Galvanized steel pipe is offered in multiple gauges, corrugations and diameters up to 144”. 

Our Oilville, Virginia location stocks 16 Gauge Galvanized Corrugated Metal Pipe in 12” – 36” diameters for same-day pick up or next-day delivery.

Larger sizes and different gauges are also available upon request. 

Aluminized steel pipe provides incredible strength, excellent corrosion resistance and a minimum 100-year service life.

Steel sheets are hot-dipped in an aluminum coating that protects against the metal pipe from corrosion.

Aluminized steel corrugated metal pipe is offered in multiple gauges, corrugations and diameters up to 144”. 

Polymer Coated Corrugated Steel Pipe has the best corrosion resistance of all of our corrugated metal pipes. Steel coils are coated with a 10-mil polymer layer that laminates the steel pipe and results in incredible corrosion and abrasion resistance.

This durable pipe has a minimum 100-year service life, is offered in multiple gauges and diameters up to 144.”

Aluminum pipe’s raw material resists corrosion without the need for additional coatings.

The corrugated metal pipe has a minimum 75-year service life and is an excellent choice for sewers and drains.

CMP Fittings and Connections

Flared End Sections

Metal end sections for corrugated steel pipe improve hydraulics and reduce scour at culverts. The metal flared end section is designed to fit corrugated metal pipe 12”- 96” in diameter.

The flared end section wraps around the drainage pipe’s barrel for a seamless fit while the toe plate prevents undercutting at culvert inlets and outlets.

Band Couplers

Metal Band Couplers connect corrugated metal pipes. These metal fittings wrap around the pipe’s end and are connected with nuts and bolts.  CMP Bands are available for steel and aluminum pipe up to 144”.
