Conduit PVC VS Hot dip galvinized Steel

Conduit PVC VS Hot dip galvinized Steel

Conduit PVC VS Hot dip galvinized Steel

(OP)
I am currently evaluating the following two types of conduits to be utilized for passing through a concrete abutment support for a  bridge crossing project. We have utilized hot dip galvanized steel conduits in the past. However, We have had situations where this type of conduit has been susceptible to corrosion issues. The conduits are to be used for a duct system which supports and protects underground electric cables.  
 
1. Rigid PVC schedule 40 DB-60 Conduit manufactured as per ASTM F-512, NEMA TC6, and TC8.

2. Hot Dip Galvanized Steel conforming to ANSI C80.1.
 
Can anyone advice if RIGID PVC schedule 40 is acceptable to be used in place of the Hot Dip Galvanized Steel for the above mentioned application. It is my understanding that Hot Dip Galvanized is to be used for locations exposed to wet locations. The strength of steel is also superior to rigid PVC schedule 40 conduit when placed in concrete where the mechanical loads around are very high. Please advice.

You're in the wrong forum.
That's an electrical code issue.
