Concrete Contractors Interstate proposed a 30-foot polished concrete wall augmented with stones and artifacts that are tailored to different sections of the 2,000 mile border.
Kelly also told lawmakers that a sharp decline in people crossing the southern border illegally was due in part to Trump's immigration policies and widely publicized arrests of immigrants living in the United States illegally.
Kelly said before his confirmation as homeland security secretary that he did not think a wall itself would resolve border security issues, and has said since that in some areas, physical barriers would be unnecessary or impractical.
But Mr Kelly told the Senate committee: "It is unlikely that we will build a physical wall from sea to shining sea".
Instead of a "beautiful wall" that Trump has promised, the federal government likely will build fencing and concrete walls in places that make the most sense. She added that members of Congress nearly uniformly rejects the idea of a 2,000-mile concrete wall and won't appropriate funds for it and asked Kelly to "speak truth to power in that regard". Also in March, the Trump administration released its FY 2018 Budget Blueprint that requests $44.1 billion in discretionary budget authority for DHS, a $2.8 billion increase from the FY 2017 annualized continuing resolution level.
The DHS chief said that each border sector will have to submit a request regarding the length of the wall or fencing it needs, and at the same time he acknowledged that there are places where the construction can not be accomplished due to the topography or because the zones are specially administered, such as Indian reservations. Smugglers have also raised prices to bring would-be immigrants from Central America through Mexico and to the border, he said.

One border wall design bidder allegedly asked if construction workers can carry a gun even in states with stringent Second Amendment restrictions to protect themselves from potential attack by violent protesters.
"You could fire a tank round at it and it will take the impact", said company founder Dennis O'Leary. "Everyone in Congress knows it's not going to happen". The wall is proposed to cover about 3200km length of US-Mexico border, while the gaps will be filled in by sensors, drones and other technology, Kelly said. Claire McCaskill said Wednesday.
"Everybody else looks at this as a construction project", Carpenter told the Los Angeles Times. "I look at this from a security standpoint".
U.S. Sen. John McCain (R-AZ) asked if the to-be-constructed wall might be interpreted as drones, towers, fences, technology to detect tunnels, an electronic wall and personnel, for instance.
"It's unlikely we will build a wall or physical barrier from sea to shining sea", Mr. Kelly said.
