Q1) I am trying to find out exactly what needs to be done to the Modified bridge rail regarding the galvanizing and acid treatment. The special Provisions say that the supplier will need to submit two samples of chemically treated galvanized steel. Is this all that we will need to do? Will the entire length of rail need to be chemically treated? What is the purpose of treating the galvanized steel?
A1) The entire length of rail (including posts - basically, all exposed metal) is to be chemically treated. Per the specifications, the contractor shall submit two samples (one 30 second wash & one 40 second wash) for approval prior to fabrication. The purpose of the treatment is to reduce the shiny surface of the metal components.
