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

A36 Hot Rolled Steel is a low-carbon steel produced by forming the metal at elevated temperatures. This process results in a material with good formability, high strength, and outstanding weldability that meets ASTM A36 specifications. It is easily fabricated using common methods like cutting, drilling, and welding without the need for pre-heating, making it a go-to material for countless structural and industrial projects.

As a medium-width flat bar, this 1-1/4" size is perfectly suited for applications requiring more substance than smaller straps. Common uses include structural bracing for frames, machine ways for guiding components, wear strips on equipment, and base plates where reliable load distribution is necessary.

Specifications

  • Material: A36 Carbon Structural Steel
  • Standards: ASTM A36
  • Strength/Tensile: 58,000-80,000 PSI
  • Dimensions: 1-1/4" Width x 1/8" Thickness x 240" Length
  • Finish: Hot Rolled (Mill Finish)
  • Certifications: Mill Test Report (MTR) available upon request

Applications

  • Construction: Structural bracing and gusset plates - excellent strength and weldability for frames.
  • Machinery Manufacturing: Machine ways and guides - provides a durable, straight edge for linear motion.
  • Industrial Maintenance: Wear strips and repair patches - cost-effective and easy to weld for equipment repair.
  • General Fabrication: Support brackets and mounting plates - versatile size for a wide range of custom parts.

Target Users

Fabricators, welders, maintenance technicians, and structural engineers rely on A36 Hot Rolled Flat Bar for its strength, weldability, and value in projects throughout the Los Angeles area.

Finish Options

This product comes standard with a hot rolled (mill) finish, characterized by a dark, scaly surface. This scale can be removed by grinding, sandblasting, or pickling prior to painting or coating. Left unfinished, it will rust. Oiling can provide temporary corrosion resistance for storage. Contact our Los Angeles sales team for custom finish inquiries.

How to Measure

Example: To order this flat bar, specify "A36 Hot Rolled Flat Bar, 1-1/4 inch by 1/8 inch".

Order Checklist

  • Product name and required dimensions (1-1/4" x 1/8")
