Corrugated Aluminum Pipe (CAP)
When defining the durability of a drainage product, both corrosion resistance and abrasion resistance must be considered. The protection afforded by aluminum’s tough, oxide surface film barrier permits aluminum to resist the detrimental effects of corrosion-abrasion cycles. Superior corrosion resistance of our Corrugated Aluminum Pipe (CAP) is achieved by a special aluminum clad culvert material. The rugged core alloy 3004-H34 is itself rated as highly corrosion resistant. But aluminum culvert coil is also clad on both sides with alloy 7072, which is anodic to the core alloy—protecting it both physically and electro-chemically against corrosion.
The aluminum alloys in our CAP have a proven history of excellent corrosion resistance. This is primarily due to a thin, tenacious, inert oxide barrier that forms on the metal surface when exposed to air. This tough, tightly-adhering oxide barrier cannot be easily removed. If damaged or affected by an aggressive environment, this oxide barrier will reform. This is referred to as a “self-healing” effect. The oxide barrier appears on the pipe surface as a grayish-white coating that will build up over time.

Corrugated Metal Pipe (CMP)
Corrugated steel pipe is similar to the superstructure
of a building in that it supports the interior walls and
gives structure to the facade. Steel is the proven, strong-shouldered
material that is coated with zinc, Aluminized
Steel Type 2, tough polymer or asphalt to increase durability
for prolonged design life. Corrugated steel pipe is the
strength at the core of all coatings and linings.
Our Corrugated Steel Pipe provides the power and tenacity
to your culverts, storm sewers and stormwater detention systems
to withstand severe environmental conditions and burial depths. We offer coatings and linings to increase the life of installations
up to 100 years as well as provide products with a Manning’s
“n” equivalent to other smooth wall drainage products.
With a multitude of pipe sizes, shapes, gages, coatings and materials options, corrugated metal pipe (CMP) products offer specifiers and users the greatest versatility and flexibility in designing drainage solutions to best fit their projects’ exact requirements. Our CMP products provide the highest service life, strength and hydraulic properties.

PVC offers excellent resistance to conventional corrosion and abrasion. It is not threatened by environmental stress cracking due to under loading or localized tensile stress, and provides soil/water tight joints. Lightweight PVC is installed with greater ease and lower cost.
The combination of materials results in an extraordinarily strong and durable pipe that sets a new industry standard. DuroMaxx is designed with a smooth inner wall for outstanding hydraulic capacity and provides the properties you can count on for long-term service and performance in the most demanding environments.
