First there were no steel "beams"at the WTC. They used trusses, not beams. The "columns" look nothing like the picture you posted. The look identical to the aluminum cladding in respect to color, shape, and length. Your own source doesn't refer to it as steel, yet here your are running around in circles with your fingers in your ears.
So basically you are saying we're wrong about something you have no understanding of; Dunning Kruger an effect of ignorance & over confidence. Oh dear someone get the snorkels the irony is getting deep. Stundied!
