Flat Bars

ASTM A36 – Hot Rolled Carbon Steel Flat Bars

ASTM A36 is the standard specification for hot rolled carbon steel used in a wide range of structural and fabrication applications. Flat bars produced under this specification offer a versatile, cost-effective solution with excellent strength, weldability, and machinability.

Hot rolled flat bars are rectangular sections with a flat surface and uniform thickness, making them ideal for applications where stability, strength, and ease of fabrication are critical.

Common uses include:

  • Structural bracing and framing
  • Support plates and base plates
  • Fabricated parts and custom components
  • Brackets, straps, and general repair work

Key benefits:

  • Excellent weldability and machinability
  • Uniform surface and consistent thickness
  • High strength-to-weight ratio
  • Easily cut, drilled, punched, bent, and welded

ASTM A36 flat bars are available in a variety of widths and thicknesses, typically stocked in 20' lengths and can be custom-cut to meet specific project requirements.
