“Do they powder coat the steel?”
Not yet, but coatings are being evaluated. The first segment completed under the Trump Program (2.25 miles West of the Calexico Port of Entry) has been painted black, but I don’t know what kind of coating they used.
The basic design calls for using “weathering” steel (also called CorTen, for its combination of CORrosion resistance and TENsile strength), which rusts on the surface, in such a way as to seal the rest of the material from deeper corrosion.
A few types of paints/coatings are now being evaluated. Powder coating is about the most the expensive of the options, but very durable.

ok, CorTen is a new process for me. it make sense from a maintenance situation as powder coating & regular painting would be too expensive.
thanks for this information.
