Multi-Plate is a versatile and economical bridge and culvert product that can be custom designed for almost any application. It is most commonly used as the steel element of a buried soil-steel structure, but it can also be part of free-standing structures such as rock fall protection, conveyer tunnels, caissons and more. This Structural Plate Corrugated Steel Pipe (SPCSP) component system is made of specially designed curved and corrugated galvanized steel plates. Structures are easily assembled in the field and installed using light construction equipment. Strata-CAT polymer coating is available for added protection in corrosive or acidic environments.
