Regarding the WTC Monument, it was suggested how the steel is rusting and needs protection from salt air. With that, another reader emailed me the following bit of info:
“The beam was originally painted c. 1970 in the shop where it was fabricated. Standard spec in those days was one coat of red oxide primer. Red oxide primer is elcheapo primer and was only done to protect the steel till the building covered it up.
You will note that the color is just like barn red paint. Both Red oxide primer and barn red paint use the same pigment which is iron oxide, a by product of steel making. It is really cheap and effective if used correctly. As a steel primer, if exposed to the elements it must have several layers of permanent paint applied over it and repainted from time to time.
I’m no paint expert, but perhaps this suggestion is necessary? This beam is such an important monument, so I’ll try to contact somebody at the VFW to see if something is planned or could be planned.
Note: I am generally interested. Not trying to stir up a controversy.
