Hot Rolled Steel Flat Bar - 2-1/2 Inch X 1/8 Inch

This 2-1/2" x 1/8" hot rolled flat bar is an A36 structural steel ideal for general fabrication. Conforming to ASTM A36, it provides 36,000 PSI minimum yield strength and excellent weldability. Its combination of strength and workability makes it a primary choice for supports. In stock Los Angeles.

  • A36 Carbon Steel Construction
  • ASTM A36 Certified
  • 58,000-80,000 PSI Tensile Strength
  • Excellent Weldability
Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

Hot rolled A36 flat bar is a low-carbon steel produced by forming at elevated temperatures, resulting in a scaly, blue-grey finish and slightly rounded edges. This process makes it cost-effective and easy to work with. Conforming to ASTM A36, it offers a minimum yield strength of 36,000 PSI and excellent weldability, making it a foundational material for structural applications where precise tolerances are secondary.

As a medium-width bar, the 2-1/2" dimension is perfectly suited for structural bracing in frames, wear strips on industrial equipment, machine ways, and base plates for medium-duty machinery. Its width provides a solid foundation without the excess weight of larger bars.

Specifications

  • Material: A36 Hot Rolled Steel
  • Standards: ASTM A36
  • Strength/Tensile: 58,000-80,000 PSI
  • Dimensions: 2-1/2" Width x 1/8" Thickness x 240" Length
  • Finish: Hot Rolled (Mill Finish)
  • Certifications: MTR Available

Applications

  • General Construction: Base plates for columns and machinery - Good compressive strength and easy to drill on-site.

Target Users

Fabricators, welders, and maintenance technicians rely on A36 flat bar for its strength and versatility in structural applications throughout the Los Angeles area.

Finish Options

This product comes standard with a hot rolled mill finish, characterized by a scaly, blue-grey surface. This mill scale should be removed by grinding or blasting before painting or coating.
