AASHTO M 218-03 (2020) PDF Download

AASHTO M 218-03 (2020) is a standard specification that defines the requirements for steel sheet that is used in the manufacturing of corrugated steel pipe (CSP) for various applications such as storm sewers, culverts, and drains. The steel sheet is coated with zinc through the hot-dip process, which provides corrosion resistance and durability. The standard identifies two specific coating weights of 610 g/m²and 1220 g/m²that are commonly used in this application.

The material is available in different forms such as coils, flat in cut lengths, and corrugated in cut lengths. This allows for flexibility and suitability for different manufacturing processes and project requirements. The standard ensures that the steel sheet meets the necessary quality and performance standards to ensure the long-term reliability and functionality of the corrugated steel pipe.
