Hot Rolled Engineered Bars

Gerdau produces special bar quality engineered hot rolled steel bar rounds in diameters ranging from 5/8" (15.875mm) to 6-1/16" (154mm), and long lengths ranging from 15' (4.6m) to 40' (12.2m), and in some locations up to 60'. These bars are converted into safety-critical parts used in the automotive, commercial, agricultural, and military segments, along with other critical applications in the oil and gas, aerospace, energy, and industrial markets. Typical applications in a vehicle include wheel hub and spindles, transmissions, differential gears and shafts, semi and full float axles, crankshafts, camshafts, connecting rods, constant velocity joints, transmission pulleys, coils springs and stabilizer bars. Other market applications would include landing gear components, bearings, sucker rods, drill collars, drill pipes, tank track parts, firearms and pressure tubing.
