CSP corrugated metal culvert

Corrugated Structural Plate (CSP) is one of the strongest structural plate products on the market today with the deepest corrugation profile possible. It allows an economical construction of long span soil-steel structures in arch, ellipse, round and box-culvert shapes. Configurations are pre-engineered to make the selection process quick and easy. Standard spans range from 4m to 18m, with longer custom designs available.


Buried steel structures build with CSP eliminate the need of bridge deck, approach slabs and expansion joints, have reduced the total lifecycle cost and require reduced maintenance.
