The claim I supposedly made was in fact a question…
The rubble was hauled away and shipped overseas without it being investigated.
Point out any claim that I should back up, and I will.
I asked you for evidence to back your claim…
Two pages of dodging now…
Baosteel Group, the nation's largest steel firm, has purchased 50,000 tons of the scrap steel from "Ground Zero," the ruins of the September 11 terrorist attack, at no more than US$120 each ton, according to yesterday's Beijing Youth Daily.
Back to you to move the goalposts.
Then I would have to refer you to the educated guess made by NIST.
BS. There has been no official investigation into the rubble and only a very small fraction was preserved.
9/11 WTC Investigation
Some 200 technical experts—including about 85 career NIST experts and 125 leading experts from the private sector and academia—reviewed tens of thousands of documents, interviewed more than 1,000 people, reviewed 7,000 segments of video footage and 7,000 photographs, analyzed 236 pieces of steel from the wreckage, performed laboratory tests and sophisticated computer simulations of the sequence of events that occurred from the moment the aircraft struck the towers until they began to collapse.

As you can see, WTC structural steel was examined.
22. Did the NIST investigation look for evidence of the WTC towers being brought down by controlled demolition? Was the steel tested for explosives or thermite residues?
NIST did not test for the residue of these compounds in the steel.

Right when it was clearly standing in the background of the reporter , thats a big screw up .

The Urban Movers mural of planes exploding into the buildings. Proven fact. If that isn't the piece de ressistence, then I don't know what is

Can you post the official report containing this research of 236 pieces.
Can you post the offiicial report on the research of the rubble of WTC7 specifically?
WTC Steel Data Collection
As of March 15, 2002, a total of 131 engineer visits had been made to these yards on 57 separate days. An engineer visit typically ranged from a few hours to an entire day at a salvage yard. The duration of the visits, number of visits per yard, and the dates the yards were visited varied, depending on the volume of steel being processed, the potential significance of the steel pieces being found, salvage yard activities, weather, and other factors.
Sixty-two engineer trips were made to Jersey City, 38 to Keasbey, 15 to Fresh Kills, and 16 to Newark. Three trips made in October included several ASCE engineers. Eleven engineer trips were made in November, 41 in December, 43 in January, 28 in February, and 5 through March 15, 2002.
D.3 Methods
Engineers identified steel members that would be considered for evaluation or tests relative to the fire and structural response of the WTC buildings. Pieces that were measured and determined to be significant were marked to be saved, and arrangements were made to have them moved to a safe location where they would not be processed (cut up and shipped). Some pieces were not saved, but samples, called coupons, were cut from them and saved for future studies.
D.3.1 Identifying and Saving Pieces
As shown in Figure D-4, the engineers searched through unsorted piles of steel for pieces from WTC 1 and WTC 2 impact areas and from WTC 5 and WTC 7. They also checked for pieces of steel exposed to fire. Specifically, the engineers looked for the following types of steel members:
Exterior column trees and interior core columns from WTC 1 and WTC 2 that were exposed to fire and/or impacted by the aircraft.
Exterior column trees and interior core columns from WTC 1 and WTC 2 that were above the impact zone. Badly burnt pieces from WTC 7.
Connections from WTC 1, 2, and 7, such as seat connections, single shear plates, and column splices. Bolts from WTC 1, 2, and 7 that were exposed to fire, fractured, and/or that appeared undamaged. Floor trusses, including stiffeners, seats, and other components.
Any piece that, in the engineer's professional opinion, might be useful for evaluation. When there was any doubt about a particular piece, the piece was kept while more information was gathered. A conservative approach was taken to avoid having important pieces processed in salvage yard operations.
The engineers were able to identify many pieces by their markings. Each piece of steel was originally stenciled in white or yellow with information telling where it came from and where it was going. A sample of the markings can be seen in Figure D-5.

Additional markings (and duplicates of stenciled markings) may sometimes be found stamped into the steel pieces. These stamped markings are about 3/4 inch tall.
In the absence of markings, member size is the quickest and easiest means for the engineers to establish an approximate original location for a piece. For example, the spandrel plates used in the column-to-column connections in the perimeters of WTC 1 and WTC 2 reportedly ranged in thickness from about 1-1/2 inches at the lower levels to as little as 3/8 inch at the upper levels.
The lighter perimeter columns from WTC 1 and WTC 2 appear to have used column-to-column connections with 4 bolts, whereas larger members presumably from lower floors used six-bolt column-to-column connections. Core column sizes vary, with some heavier sections at the lower floors having plates 4 inches thick or greater.
After a steel piece was identified for further study, it was set aside. As shown in Figure D-6, each piece was marked with spray paint, labeled "SAVE" and a piece number, such as "C-68." The engineers also advised site personnel of the location of these pieces so they would not be processed as scrap.
D.3.2 Documenting Pieces
To document the identified steel pieces of interest, the engineers measured their dimensions. They also drew sketches, and took photographs and videos of the pieces.
The steel member dimensions helped to determine the approximate building location of a piece prior to the disaster. The engineers measured and recorded dimensions using metal tape rules, vernier calipers, or other measuring devices. See Figures D-7 through D-9.

Mural Van
One of the more bizarre events of the day came in the form of a mysterious white van parked a few blocks away from the twin towers on 6th and King Street, that had a mural painted on the side that depicted a jetliner crashing into the twin towers and exploding.
This police audio transmission indicates that the two suspects in the van started to run away when the van was stopped and were apprehended shortly thereafter in some sort of struggle. The police recording also indicates that the mural van subjext to a controlled explosion following detainment of the two suspects.
Video - 911 Mural Van NYPD Recording
Further corroboration of this incident came in the form of a reference in the February 2006 Norman Y. Mineta International Institute for Surface Transportation Policy Studies (MTI) report entitled: “Saving City Lifelines: Lessons Learned in the 9-11 Terrorist Attacks”. The relevant quote is as follows:
“There were continuing moments of alarm. A panel truck with a painting of a plane flying into the World Trade Center was stopped near the temporary command post. It proved to be rented to a group of ethnic Middle Eastern people who did not speak English. Fearing that it might be a truck bomb, the NYPD immediately evacuated the area, called out the bomb squad, and detained the occupants until a thorough search was made. The vehicle was found to be an innocent delivery truck.”
