Post Tensioning

Post tensioning ductwork is a critical component that makes modern high-rise buildings, parking decks and bridges possible, and ADS manufactures the post tensioning ductwork needed for major engineering and architecture projects.

As a leader in the manufacturing of high density polyethylene (HDPE) corrugated pipe, ADS has developed chemically inert post tensioning duct that is ideal in this application. With spiral corrugated interior and exterior corrugations, ADS post tensioning duct conforms with the minimum requirements of cell classification 435400C as defined and described in the latest version of ASTM D3350.
