This 5-1/2" x 3/4" A36 Hot Rolled Steel Flat Bar is a structural grade carbon steel ideal for fabrication and construction. Conforming to ASTM A36, it offers a minimum yield strength of 36,000 PSI, excellent weldability, and good formability for heavy-duty applications. In stock Los Angeles.
- A36 Hot Rolled Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability and Formability
A36 hot rolled steel is produced by forming the metal at high temperatures, resulting in a product with a distinctive scaly, blue-grey finish and slightly rounded edges. This process makes it cost-effective and easy to work. Conforming to ASTM A36, this low-carbon steel provides reliable structural performance with excellent weldability using common methods like MIG and stick welding.
Classified as a large-width bar, this 5-1/2" wide section is ideal for applications requiring significant load-bearing capacity and a broad surface area. Common uses include structural base plates for columns and machinery, heavy equipment mounting brackets, frame components, and die components in tooling.

Finish Options
This product comes standard with a hot rolled (HR) mill finish, characterized by a scaly, blue-grey surface. This scale must be removed by grinding or sandblasting before painting or coating. For specific project requirements, other finishes may be available via special order. Contact our Los Angeles sales team for custom finish inquiries.
How to Measure
Flat bar is measured by its Width (A) and Thickness (B). Use a tape measure or calipers for an accurate reading of the two flat sides.
Example: To order this flat bar, specify "A36 Flat Bar, 5-1/2 inch wide by 3/4 inch thick".
