Corrugated Steel and Aluminum Pipe
Steel and aluminum pipe is available in a variety of corrugations and wall thicknesses in diameters up to 144”. Corrugated steel pipe is available in a number of protective coatings to provide design service life, while aluminum pipe does not require protective coating. These choices allow designers to economically match the best material to the site conditions.
Corrugated metal and spiral rib pipe are available in four different material types to economically meet the environmental and service life conditions defined for each installation.
- Galvanized Steel (minimum service life of 50 years)
- Aluminized Steel Type 2 (minimum service life of 75 -100 years)
- Aluminum Alloy (minimum service life of 75 - 100 years)
- Polymer Coated Steel (minimum service in excess of 100 years)
A two-ounce per square-foot zinc coating is applied to each side of the steel coil used to produce corrugated steel pipe, amounting to an additional thickness of 0.0017 inches on each side.
ALUMINIZED STEEL TYPE 2
Aluminized steel pipe combines the strength of steel with the corrosion resistance of aluminum. A one ounce per square foot aluminum coating is applied to each side of the steel coil used to produce corrugated steel pipe, amounting to an additional thickness of 0.0019 inches on each side.
The core material for aluminum alloy pipe is specially formulated to resist the effects of corrosion and abrasion. Corrosion resistance is further improved by cladding each surface of the core with another aluminum alloy that totals 10% of the total sheet thickness.
A 10 mil polymer film is laminated over a galvanized coated sheet to create the premier coating available today. The TRENCHCOAT™ protective film is a tough, rugged polyolefin laminate that provides galvanized CSP a durable barrier that exceeds the corrosion and abrasion resistance of all other coatings with the added feature of providing a service life in excess of 100-years.
