Hot Rolled Steel Bars

Hot Rolled Steel Bars: a low carbon hot rolled steel sometimes referred to as “mild” steel. Easily welded, machined and formed, it is used for general production, repair work, machine parts, welding jobs and bracing. It is not particularly recommended for forging, heat-treating or complicated machine operations.

Hot Rolled Steel Bar Products include:

  • Angle Bar
  • Channel
  • Flat Bar
  • Reinforcing Bar (Rebar)
  • Rounds
  • Square Bar




A36 is one of the most widely used general purpose carbon steel bars. It has a minimum yield point of 36,000 psi and the tensile strength is 58,000 – 80,000 psi.

CSA G40.21 – 44W (300w)

44W is an intermediate tensile strength carbon steel bar for use in riveted, bolted, or welded construction for general structural use.  It should not be used in low temperature applications. It has a minimum yield point of 44,000 psi and the tensile strength is 65,000 – 90,000 psi.

ASTM A-572 Grade 50

HSLA (high strength low alloy) columbium-vanadium steel with a higher yield and tensile strength as compared to ASTM A-36. It is used in bridges, buildings, construction equipment, freight cars, machinery, truck parts, and other applications. These stronger steels permit the reduction of section thickness and weight, providing added payload capacity in transportation applications as well as material cost savings. ASTM A-572, Grade 50 is weldable, formable, and machinable when using appropriate techniques. For Grade 50, the minimum yield point is 50,000 psi and the minimum tensile strength is 65,000 psi. ASTM A-572 is also available in grades 42, 60, and 65.
