Officials on Sunday blasted the auction of two steel beams salvaged from the World Trade Center — as bidders drove up the price to $1,200.

“They should not auction this memorial off,” Sen. Charles Schumer said.

The 20-ton memorial was erected more than a decade ago outside a brick company in Salem, Va. But, as The Post revealed Sunday, a Virginia auction house — on behalf of the brick company’s current owners — is now hoping to cash in, marketing it as “a very inspiring September 11 memorial salvaged from the 33rd through the 36th floors.”

The auction ends July 14.

“[The auction house] is being totally insensitive to those who lost loved ones on 9/11 and to all New Yorkers,” Schumer added.

Auctioneer Motleys Asset Disposition Group has promised a “portion of the auction proceeds” to the 9/11 Memorial Fund — but some people are dubious.

“I would say 99 percent of all the claims that say donations are going to ‘9/11 families’ or ‘9/11 organizations’ are a lie,” said Sally Regenhard, an activist who lost her firefighter son on 9/11.

“Isn’t there one single government official or fraternal organization in Virginia who can utilize this monument as a place of honor and respect?” she asked.

The Port Authority said it was “looking into” the sale.
