Corrugated Steel culvert pipes are made of carbon steel. Steel pipes with circumferential corrugation have high load bearing capacity. Culverts built with this kind of pipe segments are called corrugated steel culverts. To prevent corrosion, corrugated metal culvert pipes are usually made of galvanized carbon steel usually with a zinc coating range from 275g/m2 to 1200g/m2, which is still changeable and subject to customers’ requirements.
Our corrugated steel culvert pipes are developed in collaboration with Southeast University, which enjoys high reputation in road and bridge engineering, and are manufactured by introducing advanced American equipment. Our company standard, Common Technical Requirements on Corrugated Metal Culvert Pipes , is compiled based on ATSM standard, American National CSP Association, and in compliance with European and Japanese counterparts.
