Reply #6: galvanic corrosion? [View All]

[seemslikeadream]

Out of the blue, a new source came forward with information that in 1989 there was a plan being designed and priced to put up scaffolding, take the WTC towers down and rebuild them. The reason stated was not only asbestos related, but also because of a considerable design flaw in the WTC towers involving galvanic corrosion resulting from direct contact of dissimilar metals. In this instance, the heavy exterior aluminum panels were reportedly directly connected to the steel superstructure of the WTC towers. The price in 1989 was reportedly $5.6 billion to do this demolition and rebuilding to correct what would be a serious design flaw.

If that is the case, there would have been rapid and very damaging corrosion to the steel superstructure due to a process that is called galvanic corrosion. The Statute of Liberty had to be repaired for that same reason where the copper exterior had over time come into contact with the iron skeleton structure inside that makes the shape of the monument, so the process can occur in structures standing in air.

Evidently someone did not want to spend $5.6 billion (1989 dollars) to tear the WTC towers down and rebuild them properly, without the asbestos and without the defect that would rapidly deteriorate the superstructure of the building.
