Hot Rolled Steel Flat Bar - 3-1/2 Inch X 1/4 Inch
This 3-1/2" x 1/4" A36 Hot Rolled Steel Flat Bar provides excellent strength and weldability for structural applications. Conforming to ASTM A36, it has a minimum yield of 36,000 PSI, making it ideal for base plates and heavy supports. In stock Los Angeles.
- A36 Carbon Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability and Formability
A36 hot rolled (HR) flat bar is formed at elevated temperatures, resulting in a product with a distinctive scaly, blue-grey finish and slightly rounded edges. This process makes it more malleable and cost-effective than cold rolled steel. Primarily produced to ASTM A36 specifications, this steel offers a minimum yield strength of 36,000 PSI, ensuring reliable performance in structural roles.
As a large profile bar, the 3-1/2" width provides a stable foundation for heavy-duty applications. It is commonly used for base plates for columns and machinery, heavy structural framing components, trailer frames, and wear strips in industrial equipment where a robust section is required.
