HI EVERYONE
I would like to have some feed back about on the galvanised bolts in the underground flanges of GRE , for firefighting network new project, directly buried and in contact with soil )may be subject to corrosion or not.
I am just to see the necessity to protect these bolts by some type of coating because they will be in direct contact with soil and to avoid the corrosion potential problem.
Many thanks for your helpfull
