High-Performance Laminate Corrugated Steel Pipe (CSP) Culverts

AIL’s new HPL Pipe is one of the biggest innovations in steel drainage solutions in decades.

AIL’s new HPL Pipe has a high-strength mesh reinforcement within the polyethylene (PE) resin coating layers that provides excellent resistance to abrasion, surface damage and harsh environments. This stronger, thicker coating is twice that of standard polymer coatings.

HPL Pipe’s reinforced mesh/resin coating makes the difference

HPL Corrugated Steel Pipe will serve for up to 100 years

HPL Pipe has been designed to provide up to a 100-year service life, making it a strong alternative to concrete but with a much lower installed cost and smaller carbon footprint.
