Bar and Rod Rolling

Bar and Rod Rolling

Charter Steel's Bar and Rod rolling mills produce round, hot-rolled coil in sizes ranging from 7/32" to 1-9/16" (5.5 to 40 mm) in diameter in finished coil sizes ranging from 4,000 to 6,000 pounds. View size chart.

Produced at one of our own melt shops, we utilize a full range of billets to create special bar quality steel, including:

  • Electric Arc Furnace: Direct Cast

Maintaining the steel's surface quality and microstructural integrity is the primary focus of the rolling process. Charter Steel's walking-beam furnaces heat the billets rapidly and uniformly to prevent deformities. Precisely controlled pass designs in our finishing mills allow Charter Steel to roll tight tolerance rod and bar.

Our controlled-cooling conveyor deck carefully spreads the newly formed rod coil rings to control their microstructure as they cool. Larger diameter bar in coil product is spooled into a consistently sized coil package for uniformly slower cooling.

Quality control inspectors check dimensional characteristics and inspect the surface for any discontinuities or deformities. Additional tests may include:

  • Upset Test

  • Tensile strength

  • Reduction of area

  • Rockwell hardness

  • Microstructural evaluation

Approved material is then readied for shipment or further processing by Charter Steel. Inspectors use a spectroanalyzer to conduct a final check of the steel's chemistry just before shipping to ensure customers get exactly what they ordered.
