With a hook at the top, the rebar is in tension. The tensile strength of #3 rebar is about 50,000 pounds.

From the article:

"The ladders appear to be made with two poles of 3/8-inch rebar and four thinner poles, outfitted with steps and bent over at the end in a U, to hook on the top of the wall. It's the sort of cubed rebar support structure used in construction in Mexico, called castillo."

This configuration has been in use for decades in concrete construction and the Mexicans can crank them out all day long for almost nothing.

Also from the article:

"El Paso's urban stretch of border is littered with the rusted rebar ladders at the base on both sides — ladders lying in wait on the Mexican side, ladders pulled down by border agents or abandoned by smugglers on the U.S. side."
