US Steel has been producing "non-rusting" steel for years for structural purposes. The process involves a stable corrosion that turns the surface a deep brown and doesn't need painting. Some provisional needs for run off stain though as it does "bleed" some with rain. A good percentage of highway bridge beams are made of it. Look for it.. : USA is no. 1..

I think you're talking about Cor-Ten steel. This steel is alloyed a little bit to make a rust stain that is supposed to be protective. However, this stuff hasn't always worked as well as planned. In some places, the local atmosphere is too aggressive for the steel, and the film isn't protective. Instead, the steel just keeps making a fine rust that falls from every surface and covers everyone and everything underneath.

I believe they called it Core 10 steel.
