Homework Help: Galvanized Steel Treatment

  1. Oct 2, 2007 #1
    1. The problem statement, all variables and given/known data

    A galvanized steel roof shows small brown stains indicating minor rust. There are no penetrations of the material. What would be the most appropriate treatment and why?

    2. Relevant equations

    N/A

    3. The attempt at a solution

    The brown stains indicate that the zinc has been corroded somehow or there were un-galvanised patches to begin with, thus exposing the iron interior to oxidation. However, I am unsure of what method would be best to treat this. Any help would be appreciated, thank you.
