Overview|Specifications|Applications|Finish Options|How to Measure|Order Checklist

A36 Hot Rolled Steel is a low-carbon structural steel formed at elevated temperatures, resulting in a scaly, blue-grey mill finish and slightly rounded edges. This process makes it cost-effective and easy to work with. Conforming to ASTM A36, it provides reliable strength (36,000 PSI yield) and is one of the easiest steels to weld, drill, and form for general purpose fabrication.

As a large-format flat bar, this 10" width provides substantial surface area and strength. It is exceptionally well-suited for creating machinery base plates, heavy-duty structural braces, support brackets for industrial equipment, and components for trailer frames where rigidity and load-bearing capacity are critical.

Specifications

  • Material: A36 Hot Rolled Steel
  • Standards: ASTM A36
  • Strength/Tensile: 58,000-80,000 PSI
  • Dimensions: 10" Width x 3/8" Thickness x 240" Length
  • Finish: Hot Rolled Mill Finish
  • Certifications: MTR Available

Applications

  • Heavy Equipment: Base plates - provides a wide, stable foundation with good compressive strength.
  • Structural Fabrication: Gussets and braces - excellent weldability and high strength for reinforcing frames.
  • Transportation: Trailer frames and cross-members - durable and resistant to deformation under load.
  • General Construction: Shims and support plates - cost-effective material for leveling heavy structures.

Target Users

Fabricators, welders, and industrial maintenance crews 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 blue-grey, scaly surface. This scale must be removed before painting or coating. For specific project requirements, other services like galvanizing or sandblasting may be available. Contact our Los Angeles sales team for custom finish inquiries.

How to Measure

Flat bar is measured by its Width (the larger flat dimension) and its Thickness (the smaller dimension). Use calipers or a tape measure for accuracy.

Example: To order this flat bar, specify "A36 Hot Rolled Flat Bar, 10 inch width by 3/8 inch thickness".
