What types of measures can be taken on or around metal pipes or columns that penetrate concrete or asphalt paving to reduce corrosion at the interface?

Selected Answers

From MURRAY SCHOMBURG of QA5 LLC on January 24, 2013:
     It seems simple to do, if everyone is willing to pay for a REAL long lasting solution. In my experience stainless steel will last a lot longer when placed in the concrete or within one foot of the grade surface, say in a painted metal handrail. Most contractors shy away from, or value engineer out that solution, and we all end up with the rust-stained rail bottom, and the stained concrete surrounding the post bottoms that are a thing of beauty seemingly forever.
