This is the steel company my dad worked for. I grew up in Brighton Park neighborhood. I thought you might find this interesting.

"Wyckoff began operations in 1920 at Ambridge, Pa., and in two short years found it necessary to double the original manufacturing facilities. Now, twenty years later, this plant comprises more than 10 acres of modern buildings and railroad sidings. Served by the Main Line of the Pennsylvania Railroad--via the Pittsburgh, Fort Wayne, and Chicago Division." -- p. 4.

I don't know if this was in the Chicago or Ambridge, PA, plant or both. Normally wires are drawn. It looks like this company pulled plates of steel.
"Cold finished steel bars (CFSB) are a special steel product made by drawing, turning, grinding and/or polishing hot-rolled, special quality steel bars to give them increased strength, improved machinability, straightness, a smooth finish and dimensional accuracy. They are used as a raw material for the production of a wide variety of shafts, bushings, pinions, gears, pins, fasteners and a variety of screw machine products used in farm and industrial machinery, automobiles, trucks, and industrial equipment."
