Aluminized Steel Culvert 18″ (TDOT)

Aluminized corrugated steel pipe (CSP) is a heavy-duty drainage and culvert solution designed for real-world loading and long-term performance. The pipe is formed with structural corrugations and made from steel sheet protected by an Aluminized Type 2 (AT2) metallic coating—an aluminum coating commonly specified under AASHTO M 274 and ASTM A929—to help improve corrosion resistance in many stormwater and drainage environments. Ideal for driveway culverts, roadside drainage, and stormwater conveyance, aluminized CSP is a proven option when you want the strength of steel with the added protection of an aluminum coating.
