Design Manual

Over the past half-century, corrugated steel pipe (CSP) coatings—such as polymer-coated and aluminized Type 2 (ALT2)—have increased in popularity due to their long service life. Independent field evaluations have proven that when specified within the industry-recommended environmental conditions, polymer-coated and ALT2 CSP can provide a service life in excess of 100 years.
