- A36 Carbon Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability
A36 Hot Rolled Steel is a low-carbon structural steel produced by forming the metal at elevated temperatures. This process results in a material with slightly rounded edges and a characteristic scaly, blue-grey mill finish. It meets ASTM A36 standards, ensuring reliable mechanical properties, including good strength and excellent suitability for welding, drilling, and forming, making it a foundational material in construction and fabrication.
As a large-format flat bar, this 11-inch wide piece is engineered for applications requiring a broad, stable surface and significant structural integrity. It is commonly specified for machinery base plates, heavy-duty structural gussets, trailer frame cross-members, and large industrial brackets where load distribution and strength are critical design factors.

Finish Options
This product comes standard with a hot rolled mill finish, characterized by a blue-grey color and a surface scale from the manufacturing process. This scale must be removed by grinding or sandblasting before painting, powder coating, or galvanizing. 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 of the rectangular cross-section). Both measurements are critical for proper fit.
Example: To order this flat bar, specify "Hot Rolled Flat Bar, 11 inch by 3/8 inch".
