Lockwood Family Steel was a steel factory in National City.
The factory was founded by Peter Lockwood, then it was owned by his son, Ben Lockwood. After an Nth metal factory opened next to it, the factory closed because it didn't factor Nth metal, and the factory lost all the companies it had a contract with, one of them is L-Corp, because the Nth metal was the future, and Ben Lockwood didn't want to change the old ways. As a result; the factory was closed.
Closing the factory was one of the reasons why Ben as Agent Liberty, started his revolution against aliens under the name of Children of Liberty. Other reasons were the death of his father, the destruction of his family home during the Daxamite invasion, and the loss of his job as a history professor due to prejudice he expressed toward aliens (some of which were his students) in his lectures.
